**35 MINUTES, 44 QUESTIONS**

**Turn to Section 2 of your answer sheet to answer the questions in this section.**

**DIRECTIONS**

Each passage below is accompanied by a number of questions. For some questions, you will consider how the passage might be revised to improve the expression of ideas. For other questions, you will consider how the passage might be edited to correct errors in sentence structure, usage, or punctuation. A passage or a question may be accompanied by one or more graphics (such as a table or graph) that you will consider as you make revising and editing decisions.

Some questions will direct you to an underlined portion of a passage. Other questions will direct you to a location in a passage or ask you to think about the passage as a whole.

After reading each passage, choose the answer to each question that most effectively improves the quality of writing in the passage or that makes the passage conform to the conventions of Standard Written English. Many questions include a “NO CHANGE” option. Choose that option if you think the best choice is to leave the relevant portion of the passage as it is.

**Questions 1–11 are based on the following passage and supplementary material.**

**Physician Assistants**

As the American population grows, ages, and gains better access to affordable health insurance, the demand for primary medical services **1** __are__ expected to skyrocket. As a result, the United States Department of Health and Human Services projects a shortage of about 20,000 primary care physicians by 2020. Therefore, an important challenge facing the healthcare industry is how to address this shortfall without sacrificing quality of care. One possible solution is to **2** __elevate__ more medical school graduates to choose primary care as their field instead of **3** __their choosing the more lucrative specialties__ like surgery and dermatology.

**1**

- A) NO CHANGE
- B) is
- C) has been
- D) would be

**2**

- A) NO CHANGE
- B) interest
- C) incentivize
- D) expect

**3**

- A) NO CHANGE
- B) to choose the more lucrative specialties
- C) the more lucrative specialties
- D) the more lucrative specialties they might choose

[1] Another option is to incorporate more medical professionals like physician assistants (PAs) and nurse practitioners (NPs) into primary care teams. [2] They can talk with patients about treatment options, prescribe medications, and even **4** __perform technical procedures__ like bone marrow aspirations. [3] Many healthcare providers are moving toward this “team-based” model, **5** __where__ physicians can better focus on their specialties while relying on trained professionals to provide other necessary services. [4] Team-based medicine allows medical practitioners to best utilize their particular skills, **6** __still__ sharing the successes and struggles of the team. [5] If organized around the principles of professionalism, trust, communication, and accountability, these teams may be able to provide better care to patients at less cost. **7**

For all the promise of team-based primary medicine, it cannot work without an adequate supply of well-trained health professionals. Although the total number of PAs in the United States more than doubled between 2000 and 2010, **8** __the number of PAs going into primary care has decreased by 20%__ over that same time period. In the years ahead, we must encourage more of these new PAs to choose careers in primary care.

**4**

- A) NO CHANGE
- B) performing technical procedures
- C) technical procedures
- D) to perform technical procedures

**5**

- A) NO CHANGE
- B) whereby
- C) by this
- D) when

**6**

- A) NO CHANGE
- B) while at the same time
- C) while
- D) although

**7**

The author is considering inserting the following sentence into this paragraph.

Although they receive less training than physicians do, these professionals have advanced degrees and can provide direct treatment to patients.

Where should it be placed?

- A) After sentence 1
- B) After sentence 3
- C) After sentence 4
- D) After sentence 5

**8**

Which choice is best supported by the data in the graph?

- A) NO CHANGE
- B) the number of PAs going into primary care has increased by only 50%
- C) more PAs have gone into dermatology than into primary care
- D) the fraction of those PAs going into primary care has declined from over one-half to under one-third

Undergraduate students considering a career in medicine have many more options **9** __than they did__ just a generation ago. Graduate PA and NP programs, which take about three years, are becoming increasingly attractive, especially **10** __being that MD programs,__ __including residency, lasting__ seven to ten years and often leave students saddled with tens of thousands of dollars in debt.

Anyone thinking about pursuing a PA or NP degree should keep in mind that these programs aren”t cheap, either, and that most states impose strict limits on the kinds of treatment **11** __they__ can provide.

**9**

- A) NO CHANGE
- B) than
- C) than it was
- D) to choose from than

**10**

- A) NO CHANGE
- B) when MD programs, including residence, are lasting
- C) being that MD programs last, including residency,
- D) because MD programs, including residency, can last

**11**

- B) he or she
- C) these professions
- D) these professionals

**Questions 12–22 are based on the following passage.**

**Maria Montessori**

What is education? Is it a program of institutionally approved performances, or a collection of self-directed experiences? Such questions absorbed Maria Montessori throughout her life. Born in 1870 in **12** __Chiaravalle Italy, Montessori showed__ __a strong independent will even__ as a child. As a teenager, she told her parents that she wanted to study engineering, **13** __a position that was widely thought unladylike.__ By the age of 20, she had changed her mind and decided to pursue an even less traditional path: medicine. Despite suffering ridicule and isolation, **14** __Montessori”s medical__ __studies at the University of Rome were completed and__ __she became__ one of the first female physicians in Italy.

Although Montessori”s practice focused on psychiatry, her interests gravitated toward education. In 1900, she was appointed co-director of the *Scuola Magistrale Ortofrenica* , a training institute for special education teachers. Montessori believed that, in order for so-called “deficient” children to thrive, they needed respect and stimulation rather than **15** __the regimentation__ __they were receiving in institutions__ .

In 1907 Maria opened the Casa dei Bambini, or “Children”s House,” a daycare center for impoverished children in which she could test her theory that **16** __children”s minds each learn according to they”re own schedule.__ She personalized a curriculum for each child rather than providing a standardized course of study. While learning important academic and life skills, many formerly aggressive and unmanageable children became more emotionally balanced and self-directed. Word of her success with the Casa dei Bambini soon began to **17** __distribute__ internationally, and her methods for child-centered education became widely adopted across Europe.

**18** In the 25 years after their founding, Montessori schools were regarded as a remedy to the educational problems associated with rapid urban population growth throughout Europe.

**16**

- A) NO CHANGE
- B) each child”s mind learns according to its own schedule

**18**

Which choice provides the most effective introduction to this paragraph?

- A) Montessori dedicated herself to travelling the world and preaching the benefits of child-centered education.
- B) Montessori”s first school enrolled 50 students from poor working families.
- C) Montessori did not have a particularly nurturing relationship with her own son, Mario, who was raised by another family.
- D) As the Montessori method was gaining a foothold, Europe was undergoing dramatic social and political change.

**19** __So as__ fascism began to proliferate in the 1930s throughout Spain, Italy, and Germany, child-centered education came to be seen as a threat to the power of the state. In 1933, the totalitarian regimes in Italy and Germany closed all Montessori schools and declared **20** __them subversive and that they were undermining their power__ .

Even outside of Europe, **21** __the response to Montessori”s ideas were__ divided. Many eminent scholars, inventors, and politicians—among them Alexander Graham Bell, Helen Keller, Thomas Edison, Mahatma Gandhi, and Woodrow Wilson—greeted her ideas with enthusiasm. But her theories were challenged by William H. Kirkpatrick, a leading educational reformer and professor at Teachers College, Columbia University. His 1914 book, *The Montessori System Examined* , declared Montessori”s psychological theories wildly out-of-date. **22**

It was not until 1958 that a new generation of Montessorians revived and updated her methods in the United States. In 1958, the first American Montessori school, the Whitby School, was founded in Greenwich, Connecticut, where it thrives today.

- B) why totalitarian governments regarded Montessori”s methods as a threat
- C) those American educators whose influence was comparable to Montessori”s
- D) how other reform movements of the era contrasted with Montessori”s

**Questions 23–33 are based on the following passage.**

**Platonic Forms**

When we look at the moon, we see a spherical object, but do “spheres” really exist? This may seem to be a silly question, because it”s not hard to understand the definition of a sphere: “the set of all points in space that are a fixed distance (called the radius) from a fixed point (called the center).” We see examples of “spherical” objects all the time, don”t we?

**23** __First,__ nothing that we can observe in our physical world **24** __complies__ perfectly to this mathematical definition of a sphere. The moon, a beach ball, and even water droplets are all “bumpy,” at least at the atomic level. So can we say that the concept of “sphere” is real **25** __if there is no such thing__ as a real sphere?

Pondering this question as so many ancient Greek philosophers did, **26** __the argument Plato made was__ that the sphere is an “ideal form,” inaccessible to our physical senses yet **27** __the mind can apprehend it__ through pure reason.

- B) overlaps
- C) corresponds
- D) concurs

**25**

- A) NO CHANGE
- B) where no such thing exists
- C) as if nothing is
- D) if there were nothing

**26**

- A) NO CHANGE
- B) it was Plato who argued

- B) it can be apprehended by the mind
- C) apprehensible to the mind
- D) it is apprehensible to the mind

He also reasoned that, since our senses can be fooled, logic provides a much more reliable path to the truth. Therefore, a Platonic idealist believes that these abstract forms are **28** __as effective, if not more so, than__ sensory experience at revealing the nature of reality. **29**

Modern scientists and philosophers are unlikely to be Platonic idealists. Today, we can understand the origin of abstract concepts **30** __and not having to believe__ that they come from a higher, physically inaccessible reality. We simply need to understand **31** __the process by which our brains__ make inferences.

Take an abstract idea like “orangeness.” Most of us would say that orangeness “exists” because we see examples of it every day, such as carrots, traffic cones, and pumpkins. But what if, by some magic, we could remove all orange-colored objects from the universe? In other words, what if, as with “sphereness,” no real examples of “orangeness” **32** __would exist__ ? Would “orangeness” still exist?

**28**

- A) NO CHANGE
- B) as effective as, if not more effective than,
- C) as effective, if not more effective, than
- D) equally as effective, if not more effective than,

**29**

At this point, the author is considering adding the following true statement:

The sphere is just one of many ideal forms, like lines and tetrahedrons, that are studied in geometry.

Should the author make this addition here?

- A) Yes, because it indicates a particular application of ideal forms.
- B) Yes, because explains a claim made in the previous sentence.
- C) No, because it detracts from this paragraph”s discussion of philosophy.
- D) No, because it undermines the Platonists” point of view.

**30**

- A) NO CHANGE
- B) in not having to believe
- C) and not be believing
- D) without having to believe

**31**

- A) NO CHANGE
- B) our brain”s process by which they
- C) the process by which our brain”s
- D) the process by which our brain

**32**

- A) NO CHANGE
- B) would have existed
- C) existed
- D) had an existence

In an important sense, the answer is yes. We can demonstrate the existence of “orangeness” without appealing to any higher reality. We could measure the wavelength of red light (about 650 nm), and yellow light (about 570 nm) and make the reasonable inference, because wavelengths fall on a continuum, that a color exists with an intermediate wavelength, of 610 nm, even if we have never directly measured such light.

Our brains do not contain sophisticated instruments for measuring wavelengths of light, but they do make similar inferences constantly. **33** __For instance, when you drive, you unconsciously make inferences about quantities like the speeds of surrounding cars and qualities like dangerous driving conditions.__ Our brains are continually making inferences based on the limited information from our senses, and these inferences are the substance of abstract thought.

**33**

Which of the following changes would best improve this sentence”s cohesiveness with the rest of the paragraph?

- A) Change “For instance” to “Nevertheless.”
- B) Change both instances of “you” to “we.”
- C) Change “you unconsciously make changes” to “changes are unconsciously made”
- D) Delete the phrase “like dangerous driving conditions.”

**Questions 34–44 are based on the following passage and supplementary material.**

**The Eureka Effect**

You”ve probably had the experience. After racking your brain for hours to solve a problem, you finally put it aside and move on to other things. Then, much later, seemingly out of **34** __nowhere, perhaps__ while showering or driving—the answer suddenly strikes you. Psychologists call this the “Eureka effect,” from the ancient Greek word meaning “I have found it,” **35** __which Archimides is said to have shouted__ as he ran naked from his bathtub through the streets of Syracuse upon suddenly solving a vexing physics problem.

Does this feeling arise from our emotional centers or our cognitive centers? In other words, is it simply an emotional response to finding a solution, or does it **36** __foretell__ a fundamentally different way of thinking? Psychologists have tried to answer this question by looking inside subjects” brains as they solve problems, using electroencephalograms (EEGs) and other tools.

**34**

- A) NO CHANGE
- B) nowhere—perhaps
- C) nowhere: perhaps
- D) nowhere; perhaps

**35**

- A) NO CHANGE
- B) what Archmides is said to shout
- C) that Archimedes shouted, it is said
- D) which Archimedes it is said had shouted

**36**

- A) NO CHANGE
- B) indicate
- C) provide
- D) generate

In one **37** __experiment, subjects__ performed a word association task, scientists measured the activity in the region of the brain called the right hemisphere anterior superior temporal gyrus (RH aSTG). This region is known to be active in tasks, such as finding a theme in a story, **38** __that requires integrating and bringing together__ information from many distant parts of the brain, but is not particularly active in emotional responses.

The subjects were asked to perform a challenging verbal association task, press a button as soon as **39** __solving it__ , and report whether or not they felt the “Aha!” feeling. If they did, the response was classified as an “insight” solution. If they did not, it was classified as a “non-insight” solution.

**40** __What was interesting,__ experimenters found that the insight solutions were accompanied by an elevated level of “gamma band” activity in the RH aSTG, supporting the theory that the feeling **41** __had__ __corresponded__ to a cognitive process rather than purely an emotional one. **42**

**37**

- A) NO CHANGE
- B) experiment by which subjects
- C) experiment where subjects
- D) experiment, in which subjects

**38**

- A) NO CHANGE
- B) that require integrating and bringing together
- C) that require integrating
- D) that requires integrating

**39**

- A) NO CHANGE
- B) it was being solved
- C) they solved it
- D) it”s solution

**40**

- A) NO CHANGE
- B) The interesting thing was that
- C) It was interesting that
- D) Interestingly,

**41**

- A) NO CHANGE
- B) corresponds
- C) is corresponding
- D) will correspond

Interpreting **43** __this data is__ not a very simple matter, however. Many questions remain to be answered. For instance, does the increased gamma-band activity represent a transition of cognitive processing from an unconscious state to a conscious one? **44** __If that is true, a question would be what are the unconscious processes that are working? Also, in what way do those processes become conscious all of a sudden?__

**42**

At this point in the passage, the author wants to mention specific evidence indicated by the graph. Which statement is most justified by the data in this graph?

- A) The gamma power in the RH aSTG for the insight solution is more than double that for the non-insight solution.
- B) This increase in activity seems to begin about 0.3 seconds prior to the button-press response, and to lasts about 1 second.
- C) The gamma activity for the insight solution appears to be roughly equivalent to that for the non-insight solution until the instant the button is pushed.
- D) This increase in activity seems to begin about 0.3 seconds after the button-press response, and to last about 0.5 second.

**43**

- A) NO CHANGE
- B) this data are
- C) these data are
- D) these data is

**44**

Which of the following best combines the last two sentences into one?

- A) If so, what are the unconscious processes that are working, suddenly becoming conscious?
- B) If so, what unconscious processes are at work, and how do they suddenly become conscious?
- C) If so, what would be the unconscious processes working, and how would they suddenly become conscious?
- D) If so, what are both the unconscious process at work, and how do they suddenly become conscious?

**50 MINUTES, 1 QUESTION**

**DIRECTIONS**

As you read the passage below, consider how Steven Pinker uses

- evidence, such as facts or examples, to support his claims
- reasoning to develop ideas and connect claims and evidence
- stylistic or persuasive elements, such as word choice or appeals to emotion, to add power to the ideas expressed

**Adapted from Steven Pinker, “Mind Over Mass Media.” ©2010 by The New York Times. Originally published June 10, 2010.**

*1* New forms of media have always caused moral panics: the printing press, newspapers, paperbacks and television were all once denounced as threats to their consumers” brainpower and moral fiber.

*2* So too with electronic technologies. PowerPoint, we”re told, is reducing discourse to bullet points. Search engines lower our intelligence, encouraging us to skim on the surface of knowledge rather than dive to its depths. Twitter is shrinking our attention spans.

*3* But such panics often fail reality checks. When comic books were accused of turning juveniles into delinquents in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline. The decades of television, transistor radios and rock videos were also decades in which I.Q. scores rose continuously.

*4* For a reality check today, take the state of science, which demands high levels of brainwork and is measured by clear benchmarks of discovery. Today, scientists are never far from their e-mail and cannot lecture without PowerPoint. If electronic media were hazardous to intelligence, the quality of science would be plummeting. Yet discoveries are multiplying like fruit flies, and progress is dizzying. Other activities in the life of the mind, like philosophy, history and cultural criticism, are likewise flourishing.

*5* Critics of new media sometimes use science itself to press their case, citing research that shows how “experience can change the brain.” But cognitive neuroscientists roll their eyes at such talk. Yes, every time we learn a fact or skill the wiring of the brain changes; it”s not as if the information is stored in the pancreas. But the existence of neural plasticity does not mean the brain is a blob of clay pounded into shape by experience.

*6* Experience does not revamp the basic information-processing capacities of the brain. Speed-reading programs have long claimed to do just that, but the verdict was rendered by Woody Allen after he read *War and Peace* in one sitting: “It was about Russia.” Genuine multitasking, too, has been exposed as a myth, not just by laboratory studies but by the familiar sight of an SUV undulating between lanes as the driver cuts deals on his cellphone.

*7* Moreover, the evidence indicates that the effects of experience are highly specific to the experiences themselves. If you train people to do one thing, they get better at doing that thing, but almost nothing else. Music doesn”t make you better at math; conjugating Latin doesn”t make you more logical; brain-training games don”t make you smarter. Accomplished people don”t bulk up their brains with intellectual calisthenics; they immerse themselves in their fields. Novelists read lots of novels; scientists read lots of science.

*8* The effects of consuming electronic media are also likely to be far more limited than the panic implies. Media critics write as if the brain takes on the qualities of whatever it consumes, the informational equivalent of “you are what you eat.” As with primitive peoples who believe that eating fierce animals will make them fierce, they assume that watching quick cuts in rock videos turns your mental life into quick cuts or that reading bullet points and Twitter postings turns your thoughts into bullet points and Twitter postings.

*9* Yes, the constant arrival of information packets can be distracting or addictive, especially to people with attention deficit disorder. But distraction is not a new phenomenon. The solution is not to bemoan technology but to develop strategies of self-control, as we do with every other temptation in life. Turn off e-mail or Twitter when you work, put away your BlackBerry at dinner time, ask your spouse to call you to bed at a designated hour.

*10* And to encourage intellectual depth, don”t rail at PowerPoint or Google. It”s not as if habits of deep reflection, thorough research and rigorous reasoning ever came naturally to people. They must be acquired in special institutions, which we call universities, and maintained with constant upkeep, which we call analysis, criticism and debate. They are not granted by propping a heavy encyclopedia on your lap, nor are they taken away by efficient access to information on the Internet.

*11* The new media have caught on for a reason. Knowledge is increasing exponentially; human brainpower and waking hours are not. Fortunately, the Internet and information technologies are helping us manage, search, and retrieve our collective intellectual output at different scales, from Twitter and previews to e-books and online encyclopedias. Far from making us stupid, these technologies are the only things that will keep us smart.

Write an essay in which you explain how Steven Pinker builds an argument to persuade his audience that new media are not destroying our moral and intellectual abilities. In your essay, analyze how Pinker uses one or more of the features listed in the box above (or features of your own choice) to strengthen the logic and persuasiveness of his argument. Be sure that your analysis focuses on the most relevant features of the passage.

Your essay should NOT explain whether you agree with Pinker”s claims, but rather explain how Pinker builds an argument to persuade his audience.

**DIAGNOSTIC SAT DETAILED ANSWER KEY**

**Section 1: Reading**

__1__ . **C**

**Specific Purpose**

Let”s translate this question into a “stand-alone” question: “How is Smith”s work presented in the first paragraph?” The passage states (line 3) that *Karl Smith has a good rule of thumb for* *categorizing* *epidemics* , then goes on to describe various types of epidemics in an effort to help visualize the types of spread. In other words, he is proposing a model for *conceptualizing phenomena* . (Note that the word *phenomena* refers simply to common occurrences. It has a neutral tone, not a positive one.)

__2__ . **A**

**Inference**

The passage states in lines 67–72 that *Nevin”s paper was almost completely ignored* because *Nevin was an economist, not a criminologist, and his paper was published in* Environmental Research, *not a journal with a big readership in the criminology community* . In other words, Nevin”s paper was ignored because it *was not presented by authorities with the proper credentials* .

__3__ . **C**

**Textual Evidence**

As the explanation to question 2 indicates, the evidence for this answer is lines 67–72, which includes the statement in (C).

__4__ . **B**

**Inference from Data**

According to the graph, in 1963 there were 150 violent crimes per 100,000 capita, and in 1993 there were 750 violent crimes per 100,000 capita. This is an increase of 600 crimes per 100,000, and 600 is 400% of 150.

__5__ . **D**

**Inference from Data**

Nevin”s hypothesis is phrased in the form of a question in lines 27–28: *Maybe reducing lead exposure had an effect on violent crime too?* Therefore, the portion of the graph that would *least* support his hypothesis is the portion that shows the *least* correlation between lead exposure and crime. The biggest gap in the two graphs (and hence the portion that provides the least support for his thesis) corresponds to the set of violent crime statistics from 2003 to 2013.

__6__ . **C**

**Specific Purpose**

The *sales of vinyl LPs* are mentioned to describe a statistic that also happens to correlate with preschool blood lead levels, thereby making the point that *a single correlation between two curves isn”t all that impressive, econometrically speaking* … *No matter how good the fit, if you only have a single correlation it might just be coincidence* . Hence, it is a statistic that may be more coincidental than explanatory.

__7__ . **D**

**Interpretation**

The sentence in lines 21–24 indicates that *lead exposure in small children [had been linked] with a whole raft of complications later in life, including lower IQ, hyperactivity, behavioral problems, and learning disabilities* . These *complications* are *psychological problems* for those exposed to lead at a young age.

__8__ . **A**

**Interpretation**

When the passage states that the *drivers* were *unwittingly creating a crime wave two decades later* (lines 63–64), it indicates that they were *inadvertent abettors* .

__9__ . **B**

**Word in Context**

The phrase *even better* (line 49) refers to the finding mentioned in the previous sentence that *the similarity of the curves was as good as it seemed* , suggesting that the data showed an even stronger correlation than Nevin had hoped.

__10__ . **D**

**Specific Purpose**

The final paragraph discusses the fact that the *gasoline lead hypothesis* explains many additional phenomena, such as the difference between the murder rates in large cities (where there are lots of cars) and small cities (where there are fewer cars and therefore less lead exhaust exposure). These implications further support the hypothesis.

__11__ . **B**

**Cross-Textual Inference**

The author of Passage 1 indicates that Hemingway was a legendary figure whose work *seemed … to have been carved from the living stone of life* (lines 25–26) and therefore had a great impact on the author and his friends. Passage 2, however, suggests that Hemingway”s works don”t have the impact they once did, saying that they *now seem unable to evoke the same sense of a tottering world that in the 1920s established Ernest Hemingway”s reputation* (lines 48–50) and *no longer seem to penetrate deeply the surface of existence* (lines 57–58). Therefore, the two passages disagree most strongly on the *incisiveness* (deep analytical quality) of Hemingway”s work.

__12__ . **C**

**Textual Evidence**

As the answer to the previous question indicates, the best evidence for this answer is found in lines 24–26 and lines 56–58.

__13__ . **C**

**Cross-Textual Interpretation**

The author of Passage 1 regards Hemingway as a *legend* (line 16) whose *impact upon us was tremendous* (lines 18–19), but the author of Passage 2 calls Hemingway a *dupe of his culture rather than its moral-aesthetic conscience*(lines 66–67).

__14__ . **D**

**Cross-Textual Inference**

The author of Passage 1 indicates that, although Hemingway”s work had a strong formative impact on him, it ultimately could not capture the true horrors of war that he and his friends were later to encounter:

*The Hemingway time was a good time to be young. We had much then that the war later forced out of us, something far greater than Hemingway”s strong formative influence* (lines 33–36).

Likewise, the author of Passage 2 indicates that Hemingway”s work did not fully capture the horrors of war: *We have had more war than Hemingway ever dreamed of* (lines 53–54) … *yet Hemingway”s great novels no longer seem to penetrate deeply the surface of existence* (lines 56–58).

__15__ . **A**

**Word in Context, Purpose**

In saying that *the words he put down seemed to us to have been carved from the living stone of life* (lines 24–26), the author of Passage 1 means that Hemingway”s words represent living truths that have the weight and permanence of stone carvings. In other words, his words represent the *salient* (prominent and important) *experience* of life.

__16__ . **D**

**Interpretation**

In saying that *we began unconsciously to translate our own sensations into their terms and to impose on everything we did and felt the particular emotions they aroused in us* (lines 28–32) the author is saying that he and his friends *identified* with Hemingway”s language.

__17__ . **B**

**Inference**

According to Passage 1, the *lessons that [Hemingway] had to teach* (line 43) included the example he set as a war correspondent *writing a play in the Hotel Florida in Madrid while thirty fascist shells crashed through the roof* (lines 10–12) and as a soldier *defending his post singlehandedly against fierce German attacks* (lines 13–15), both of which exemplify *confidence in the face of danger* .

__18__ . **D**

**Specific Purpose**

The phrase *a tottering world* (line 49) is used to describe the Europe of the 1920s that Ernest Hemingway depicts in his novels. The author compares this world to one whose *social structure is … shaken* (lines 51–52) and which had *more war than Hemingway ever dreamed of* (line 54). In other words, a world filled with *societal upheaval* .

__19__ . **C**

**Cross-Textual Inference**

The author of Passage 1 clearly views Hemingway as a personal and literary hero. Hence, a withering accusation such as the one in Passage 2 that *Hemingway, in effect, became a dupe of his culture rather than its moral-aesthetic conscience* (lines 66–67) would almost certainly be met with *vehement disagreement* .

*Tip:* Questions about how the author of one passage might *most likely* respond to some statement in another passage require us to focus on the *thesis and tone* of that author. Before attempting to answer such questions, remind yourself of the central theses of the passages.

__20__ . **B**

**Textual Evidence**

The best evidence for this answer comes from lines 28–32, where the author of Passage 1 says that *we began to unconsciously translate our own sensations into their terms and to impose on everything we did and felt the particular emotions they aroused in us* . In other words, Hemingway was in fact a kind of *moral-aesthetic conscience* for the author of Passage 1 and his friends.

__21__ . **B**

**Interpretation**

Passage 2 states that Hemingway”s novels *yielded to the functionalist, technological aesthetic of the culture instead of resisting in the manner of Frank Lloyd Wright* (lines 63–66). In other words, Frank Lloyd Wright was more *iconoclastic* (culturally rebellious) than Hemingway.

__22__ . **C**

**Specific Purpose**

The first paragraph establishes the idea that *atoms, the building blocks of everything we know and love … don”t appear to be models of stability* , a fact that represents a *scientific conundrum* (riddle), because instability is not a quality that we expect of *building blocks* .

__23__ . **D**

**Word in Context**

By asking *[w]hy are some atoms, like sodium, so hyperactive while others, like helium, are so aloof?* the author is drawing a direct contrast between chemical reactivity and relative *nonreactivity* .

__24__ . **D**

**Inference**

This question, about why protons stick together in atomic nuclei, is the guiding question for the passage as a whole. The next paragraph analyzes this question in more detail, explaining why this well-known fact is actually so puzzling. The remainder of the passages discusses attempts to resolve this puzzle, which remains at the heart of quantum physics.

__25__ . **A**

**Textual Evidence**

The evidence that this question represents a *central conundrum* is found in lines 1–5, where the author makes the uncontroversial claim that *a sound structure requires stable materials* , but then makes the paradoxical claim that *atoms, the building blocks of everything we know and love … don”t appear to be models of stability* .

__26__ . **A**

**Specific Purpose**

The two sentences in lines 13–19 (*We are told* … *electrons. We are also told … closer* ) indicate that we, the educated public, have been taught two seemingly contradictory facts about atoms. In other words, these are *predominant conceptions* .

__27__ . **C**

**Inference from Data**

In the graph, the equilibrium point is indicated by a dashed vertical line labeled *Equilibrium* . If we notice where this line intersects the two curves, we can see that the corresponding electrostatic force is precisely opposite to the corresponding strong nuclear force. That is, the equilibrium point is where the two forces “cancel out” and have a sum of 0.

__28__ . **C**

**Inference from Data**

*Tip:* When a question asks about a graph or table, it helps to circle the words or phrases in the question that correspond to the words or phrases in the graph or table. In this case, circle the key phrases *electrostatic repulsion* and *separated by 1.5 femtometers* in both the question and the graph.

Now, if we go to the graph and find the vertical line that corresponds to a *separation of 1.5 femtometers* , we can see that it intersects the curve for *electrostatic force* at the horizontal line representing 10^{2} , or 100, Newtons.

__29__ . **C**

**Interpretation**

In the fourth paragraph, we are told that Hideki Yukawa *proposed that the nuclear force was conveyed by a then-undiscovered heavy subatomic particle he called the pi meson (or “pion”), which (unlike the photon) decays very quickly and therefore conveys a powerful force only over a very short distance* (lines 44–49). However, his theory *was dealt a mortal blow by a series of experiments … that demonstrated that pions carry force only over distances greater than the distance between bound protons* (lines 50–55). In other words, pions are *ineffective in the range required by atomic theory* , so they cannot be the carriers of the strong nuclear force.

__30__ . **B**

**General Structure**

The first paragraph of this passage introduces the *scientific conundrum* of how protons adhere in atomic nuclei. The second paragraph analyzes this strange situation. The third paragraph describes a force, the strong nuclear force, that could solve the conundrum. The fourth paragraph describes a particular theory, now refuted, about what might convey this strong nuclear force. The fifth and sixth paragraphs indicate that the problem has yet to be satisfactorily resolved. Thus, the passage as a whole is *a description of a technical puzzle and the attempts to solve it* .

__31__ . **A**

**Literary Devices**

A **rhetorical question** is a question intended to convey a point of view, rather than suggest a point of inquiry. Although the first and second paragraphs include five questions, they are all inquisitive, not rhetorical.

The passage includes **illustrative metaphors** in lines 15–16 (*a cloud of speedy electrons* ) and lines 55–56 (*a plumber”s wrench trying to do a tweezer”s job* ), **technical specifications** in lines 29–40 (*First, it can”t have … each other* ), and **appeals to common intuition** in lines 1–2 (*a sound structure … materials* ) and lines 13–16 (*We are . . . electrons* ).

__32__ . **B**

**Word in Context**

The hope that *QCD ties up atomic behavior with a tidy little bow* is the hope that the QCD theory *resolves* the problem in a tidy way.

__33__ . **C**

**General Purpose**

The passage as a whole develops the thesis that *the wise legislator does not begin by laying down laws good in themselves, but by investigating the fitness of the people, for which they are destined, to receive them* (lines 3–6). In other words, the passage is concerned with *examining the social conditions that foster effective legal systems* .

__34__ . **C**

**Word in Context**

In saying that *the architect sounds the site to see if it will bear the weight* , the author means that the architect *probes* the proposed location for a building to make sure that it is safe to build upon.

__35__ . **A**

**Specific Purpose**

The analogy of the architect in the first paragraph illustrates the thesis of the passage that *the wise legislator does not begin by laying down laws good in themselves, but by investigating the fitness of the people, for which they are destined, to receive them* (lines 3–6). That is, that a *nation”s civil code depends on the nature of its people* . Choice (B) is incorrect because the analogy is not about the *foundational principles* of laws, but rather the *fitness of the people* for whom they are intended.

__36__ . **A**

**Inference**

The author states that as a nation grows older, its citizens *become incorrigible* (unable to be improved). *Once customs have become established and prejudices inveterate* (deep-seated), *it is dangerous and useless to attempt their reformation* (lines 19–21). That is, the people become stubbornly resistant to political change.

__37__ . **B**

**Textual Evidence**

As the explanation to the previous question indicates, the relevant evidence is found in lines 20–21.

__38__ . **B**

**Interpretation**

When the author says that *[m]ost peoples, like most men, are docile only in youth* (lines 17–18), he is saying that societies (the *peoples* ) as well as individuals (*men* ) become less manageable as they age.

__39__ . **B**

**Specific Purpose**

The author refers to *Sparta at the time of Lycurgus* (line 35) as an example of *a state, set on fire by civil wars, [which] is born again* (lines 31–32). That is, a *society rejuvenated by conflict* . Choice (A) may seem tempting, because the beginning of the paragraph mentions the fact that *periods of violence* (lines 28–29) can make people *forget the past* , but the paragraph explains that this forgetting has the effect of renewal, not paralysis.

__40__ . **B**

**Interpretation**

Although the word *constitution* can be used to mean *the documented rules by which a nation defines its governmental institutions* (as in the *Constitution of the United States of America* ), the phrase *the constitution of the state* , as it is used in this passage, clearly refers to the *composition* of the state, that is, the people who constitute the nation.

__41__ . **A**

**Interpretation**

In saying that *[o]ne people is amenable to discipline from the beginning; another, not even after ten centuries* (lines 51–53), the author means that some nations are *ready to be governed by the rule of law* as soon as they are founded, but others require much more time.

__42__ . **D**

**Inference**

The passage states that *Peter the Great … lacked true genius [because he] did not see that [his nation] was not ripe for civilization: he wanted to civilize it when it needed only hardening* (lines 55–61). In other words, he did not give his nation the *hardening* it needed: his flaw was his *irresolution* (hesitancy due to a lack of conviction) *in exerting control* .

__43__ . **C**

**General Purpose**

The first sentence of the passage establishes its central purpose: *to understand the views of Aristotle* , and asserts that to do this *it is necessary to apprehend his imaginative background* (lines 1–3). In other words, the purpose of this passage is to *describe the conceptions that inform a particular mindset* .

__44__ . **B**

**Interpretation**

When the author states that *Animals have lost their importance in our imaginative pictures of the world* (lines 29–30), he is reinforcing his point that modern students *are accustomed to automobiles and airplanes; they do not, even in the dimmest recesses of their subconscious imagination, think that an automobile contains some sort of horse inside, or that an airplane flies because its wings are those of a bird possessing magical powers* (lines 23–29). In other words, *animistic beliefs no longer inform our physical theories* .

__45__ . **D**

**Interpretation**

When the author states that every *philosopher, in addition to the formal system that he offers to the world, has another much simpler system of which he may be quite unaware* (lines 3–6), the *simpler system* refers to the *imaginative background* (line 3) that informs a scientist”s formal theories. However, if a scientist is aware of this simpler system, *he probably recognizes that it won”t do* (line 7). Therefore, this system is a *relatively unrefined way of thinking* .

__46__ . **A**

**Inference**

In lines 61–65, the author states that *It was natural that a philosopher who could no longer regard the heavenly bodies themselves as divine should think of them as moved by the will of a Divine Being who had a Hellenic love of order and geometric simplicity* . In other words, the astronomical theories of some ancient Greek philosophers were closely associated with their religious ideas.

__47__ . **A**

**Textual Evidence**

As the explanation to the previous question indicates, the evidence for this answer is in lines 61–65.

__48__ . **D**

**Word in Context**

When the author states that, to the Greek*, it seemed more natural to assimilate apparently lifeless motions to those of animals* (lines 46–47), he means that the ancient Greeks found it easy to *liken* the motion of machines to the motion of animals.

__49__ . **D**

**Inference**

The passage states that *To the ancient Greek, attempting to give a scientific account of motion, the purely mechanical view hardly suggested itself, except in the case of a few men of genius such as Democritus and Archimedes* . In other words, most Greeks were not inclined toward the mechanical view, except for the men of genius, who had more accurate *metaphors for the laws of motion, and therefore were “willing to disregard conventional wisdom.”*

__50__ . **C**

**Inference**

As it is discussed in the passage, the *apparent gulf between animals and machines* (lines 44–45) is the ever-shrinking gap between the animistic and the mechanistic view of animal physiology. To the modern scientist, each piece of evidence that demonstrates how *the body of an animal is a very elaborate machine, with an enormously complex physical and chemical structure* (lines 41–43) serves to bridge this gulf. One example of such evidence might be *the mechanical laws that describe bumblebee flight* .

__51__ . **B**

**Inference**

The first paragraph discusses the fact that *the views of Aristotle* (line 1) are *due to his imaginative preconceptions, or to what Santayana calls “animal faith”* (lines 17–18), which the author goes on to explain include *animistic tendencies* , that is, tendencies toward seeing living spirits in all physical phenomena.

__52__ . **D**

**Textual Evidence**

Lines 45–47 also reinforce the author”s point that Aristotle, like other ancient Greeks, was inclined toward an animistic view of the world: *To the Greek, it seemed more natural to assimilate apparently lifeless motions to those of animals* .

__1__ . **B**

**Subject-Verb Agreement**

The subject of this verb is *demand* , which is singular. Therefore, *are* must be changed to *is* .

__2__ . **C**

**Diction**

This question asks you to choose the word that best fits the semantic context of the sentence, that is, the word that helps the sentence to convey a logical idea in the context of the paragraph.

This previous sentence states that *an important challenge facing the healthcare industry is how to address this shortfall without sacrificing quality of care* . Among our options, the only one that suggests a *possible solution* to this problem is *to incentivize more medical school graduates to choose primary care* .

Although it may seem that *interest* is a reasonable choice, notice that its use would violate idiom in this sentence: the correct idiom is not *interest someone to do something* , but rather *interest someone in doing something* .

__3__ . **C**

**Logical Comparisons**

This portion of the sentence is part of a parallel construction in the form *A instead of B* . In such constructions, the words or phrases in *A* and *B* must have the same grammatical form and describe logically comparable (or contrastable) things. Since in this case *A* is *primary care* (a noun phrase indicating a medical specialty), the most logical choice for *B* is *the more lucrative specialties* (a noun phrase indicating medical specialties). The original phrasing is incorrect because *their choosing* does not indicate a medical specialty, (B) is incorrect because *to choose* does not indicate a medical specialty, and choice (D) is incorrect because it is redundant.

__4__ . **A**

**Parallelism**

Words or phrases in a list should have the same grammatical form. In the original phrasing, the three items in the list are all present tense verbs: *talk … prescribe … perform* .

__5__ . **B**

**Diction**

Because a *“team-based” model* is not a location, the use of the pronoun *where* is incorrect. Likewise, choice (D) *when* is incorrect because a *“team-based” model* is not a time. Choice (C) is incorrect because it produces a comma splice. The correct answer is (B) *whereby* , which means *by which* .

__6__ . **C**

**Diction**

The adverb *still* means *even now* or *nevertheless* , neither of which fit the logical context of this sentence. Only choice (C) *while* , meaning *at the same time* , fits logically. Choice (B) *while at the same time* is redundant, and choice (D) *although* implies a contrast, which is illogical.

__7__ . **A**

**Coordination of Ideas, Cross-References**

The subject of the inserted sentence is *these professionals* . The pronoun *these* requires an antecedent, which is best provided if the sentence is placed after sentence 1, which specifies *medical professionals like physician assistants (PAs) and nurse practitioners (NPs)* .

__8__ . **D**

**Data Analysis**

The descending line in the graph shows clearly that the percentage of PAs in primary care has declined from 51% in 2000 (over one-half) to 31% in 2010 (under one-third).

__9__ . **A**

**Logical Comparisons, Pronoun-Antecedent Agreement**

This sentence is correct as written. The pronoun *they* agrees in number and kind with its antecedent *students* , and the comparison is logical. Choice (D) is redundant.

__10__ . **D**

**Idiom, Pronoun-Antecedent Agreement**

Using the phrase *being that* to mean *because* is colloquial and nonstandard for written American English, therefore choices (A) and (C) are incorrect. Choice (B) is incorrect because *when* should only be used to refer to a time.

__11__ . **D**

**Pronoun-Antecedent Agreement, Cross-References**

The definite pronoun *they* must refer to some plural noun, but the only possible plural antecedent in this sentence is *programs* , which would be illogical. Choice (D) clarifies the reference.

__12__ . **C**

**Punctuation**

The four choices differ only in their punctuation. Any reference to a city-and-country or city-and-state must separate the two with commas: e.g. *London, England* or *Providence, Rhode Island* . Therefore the original punctuation in (A) is incorrect. Choice (B) is incorrect because it produces a sentence fragment. Choice (D) is incorrect because it misuses the semicolon: the two phrases on either side of the semicolon should be independent clauses.

__13__ . **B**

**Logic, Dangling Participles**

Since *engineering* is a class of profession and not a *position* , the original phrasing is illogical. Choice (C) is incorrect because it is a dangling participial phrase: the past participle *considered* does not share a subject with the main clause. Choice (D) is incorrect because the phrase *in reputation* is not idiomatic.

__14__ . **D**

**Dangling Participles**

The sentence begins with the participial phrase *suffering ridicule and isolation* . Any participial phrase must have the same subject as the main clause. In the original phrasing, the subject of the main clause is *Montessori”s medical studies* , but this cannot be the subject of *suffering ridicule and isolation* . Therefore, choices (A) and (C) are both incorrect. Choices (B) and (D) both correct this problem by changing the subject of the main clause to *Montessori* , but (B) is incorrect because the phrase *by becoming* is illogical.

__15__ . **A**

**Parallelism**

This sentence contains the parallel construction *A rather than B* . The original phrasing provides parallel phrasing: *respect and stimulation* shares the same grammatical form and semantic category as *the regimentation* . Choice (D) provides a parallel phrasing but illogically implies that the students *were receiving* institutions.

__16__ . **B**

**Diction, Agreement**

The original phrasing is incorrect because *they”re* is a contraction of *they are* , which is illogical in this context. Choice (C) is incorrect because *childrens”* is not a word at all. *Children* is the plural form of *child* , and the possessive form of *children* is *children”s* . Choice (D) is incorrect because *their* disagrees in number with the antecedent *each* .

__17__ . **C**

**Diction**

This sentence discusses how word of Montessori”s success with her school began to *spread* of its own merit and accord. Choices (A) and (D) are incorrect because both *distribute* and *exhibit* imply intentional action. Choice (B) is illogical: *word* of someone”s success cannot *increase* .

__18__ . **D**

**Logical Cohesiveness**

To understand which sentence most effectively introduces this paragraph, we must first understand what the paragraph is about. As a whole, the paragraph discusses how *Montessori schools were regarded as a remedy to the educational programs associated with rapid urban population growth in Europe* … but then *came to be seen as a threat to the power of the state* . Choice (D) encapsulates this idea the best.

__19__ . **C**

**Logical Transitions**

Choice (C) provides the most logical transition between ideas in the paragraph: the shift from a positive view of Montessori”s work to a negative view requires a contrasting transition like *however* .

__20__ . **D**

**Redundancy**

The original phrasing is redundant: being *subversive* is the same as *undermining power* . The most concise correct phrasing is that in (D).

__21__ . **B**

**Subject-Verb Agreement**

In the original phrasing, the subject *response* (singular) disagrees with the verb *were* (plural) *divided* . Choice (B) provides the most effective correction.

__22__ . **A**

**Logical Cohesiveness**

The remarkable thing about this paragraph is its introduction of dissenting views on Montessori”s work from within the field of education, rather than merely from political opponents. Any additional discussion in this paragraph should elaborate on the nature of that dissent in the educational community. Only choice (A) extends the discussion in a relevant way.

__23__ . **D**

**Redundancy**

This sentence is asserting a claim that directly contrasts the point of view presented in the previous paragraph. Choice (D) *In fact* , introduces just such an assertion. Choice (A) *First* is incorrect because this claim is not part of an enumerated list. Choice (B) *So* is incorrect, because this sentence is not asserting a logical consequence of the previous claim. Choice (C) *While* is incorrect because it produces a sentence fragment.

__24__ . **C**

**Diction, Idiom**

The original phrasing is incorrect because the phrase *complies [to]* is not idiomatic. The same is true of (B) *overlaps [to]* and (D) *concurs [to]* . Choice (C) *corresponds [to]* , however, is idiomatic and logical.

__25__ . **A**

**Coordination of Ideas**

This phrase is correct as written. It is expressing a condition, and so the use of the conjunction *if* is correct.

__26__ . **D**

**Dangling Participles**

The participle *pondering* and the main clause must share the same subject, or else the participle “dangles.” Who was *pondering* ? Plato. Therefore *Plato* must be the subject of the main clause. Choice (C) is incorrect, however, because there is no need for the past participle form *had argued* .

__27__ . **C**

**Parallelism**

The sentence contains the parallel construction *A yet B* . The phrasing *inaccessible … yet apprehensible* provides a parallel form, since both *inaccessible* and *apprehensible* are adjectives.

__28__ . **B**

**Modifier Usage**

The phrase between the commas is an interrupting modifier. Any sentence should remain grammatically complete even when any interrupting modifier is removed. Notice that if we did this with the original sentence, it would read *as effective … than sensory experience* , which is clearly unidiomatic. (The correct comparative idiom is *as effective as* .) The only choice that corrects this problem is (B).

__29__ . **C**

**Logical Cohesiveness**

The information the author is proposing does not fit with the discussion about the philosophy of Platonic idealism.

__30__ . **D**

**Modifier Form**

In the original phrasing, the conjunction *and* is incorrect because it does not conjoin comparable words or phrases; therefore, choices (A) and (C) are incorrect. In choice (B) the prepositional phrase *in not having to believe* is illogical. Choice (D) is correct because the prepositional phrase *without having to believe* logically modifies the verb *understand* .

__31__ . **A**

**Possessives**

This sentence is correct as written. Choice (B) is incorrect because the pronoun *they* has no clear antecedent. Choice (C) misuses the possessive *brain”s* , and choice (D) yields the subject-verb disagreement *brain make* .

__32__ . **C**

**Verb Mood**

This clause is part of a counterfactual hypothesis. As we discuss in __Chapter 4__ , Lesson 30, a present counterfactual hypothesis takes the form of the present subjunctive mood, which is usually the same form as the simple past tense: *existed* .

__33__ . **B**

**Pronoun Consistency**

Since the previous sentence refers to *our brains* , pronoun consistency requires that this sentence continue to use the first-person plural pronoun *we* .

__34__ . **B**

**Coordination of Clauses**

The interrupting modifier (*perhaps while showering or driving* ) must be “bracketed” on either end by commas, em dashes, or parentheses. Since it clearly ends with an em dash, it must start with an em dash as well.

__35__ . **A**

**Pronoun Form**

This sentence is correct as written. Choice (B) uses the wrong pronoun form *what* and incorrectly implies that Archimedes is shouting in the present. Choice (C) uses the wrong pronoun form *that* and misplaces the modifying clause *it is said* . Choice (D) misuses the past perfect form *had shouted* .

__36__ . **B**

**Diction**

The sentence discusses the relationship between the *feeling* of the Eureka effect and *a fundamentally different way of thinking* . In the context of the discussion, the only choice that indicates a logical relationship is (B): this feeling *indicates* a different way of thinking.

__37__ . **D**

**Coordination of Clauses**

The original phrasing is incorrect because it includes a comma splice. Choice (B) is incorrect because the prepositional phrase *by which* is illogical. In choice (C), the use of the pronoun *where* is incorrect because an experiment is not a place.

__38__ . **C**

**Subject-Verb Agreement, Redundancy**

The verb *requires* (singular) disagrees with the subject *tasks* (plural), therefore choices (A) and (D) are incorrect. Choice (B) is redundant.

__39__ . **C**

**Subject-Verb Agreement**

The modifying phrase *as soon as solving it* is vague and awkward. Choice (C) clarifies the modifier by indicating that the *subjects* are solving the task.

__40__ . **D**

**Awkwardness, Logical Transitions**

The underlined phrase is a sentence modifier, that is, a phrase that modifies the statement in the main clause *experimenters found* . Choices (A), (B), and (C) are needlessly awkward and wordy, but choice (D) provides a concise and clear modifier.

__41__ . **B**

**Verb Tense**

This clause is describing a general fact (*the theory that* …), not an event. To express general facts, we use the simple present tense: *corresponds* .

__42__ . **B**

**Data Analysis**

According to the graph, the line indicating the Insight condition separates from the line representing the Non-insight condition approximately 0.3 seconds prior to the button being pushed, and remains elevated until about 0.7 seconds after the button is pushed, for a duration of approximately 1 second.

__43__ . **D**

**Pronoun-Antecedent Agreement, Subject-Verb Agreement**

The verb *is* agrees with the subject *interpreting* (both are singular), but the pronoun *this* disagrees with its antecedent *data* (*this* is singular, but *data* is plural).

__44__ . **B**

**Coordinating Clauses**

The correct choice should combine the two questions into a single sentence. Choice (A) misstates the second question. Choice (C) inappropriately uses the subjunctive mood. Choice (D) misuses the parallel construction *both A and B*.

On the drawing, we should first mark the areas of the three faces. The front and back faces both have an area of 3*a* . The left and right faces both have an area of 3*b* .

*C* (*n* ) = *an* + *b*

Since this expression is linear in *n* (the input variable, which represents the number of necklaces produced), the constant *a* represents the slope of this line, which in turn represents the “unit rate of increase,” in other words, the increase in total cost for each individual necklace produced.

The constant *b* represents the “*y* -intercept” of this line, which in this case means the costs when *n* = 0 (that is, the fixed costs before any necklaces are produced).

**Algebra (lines) MEDIUM**

To find the slope of line *l* , we can find two points on *l* and then use the slope formula.

*f* (*x* ) = 2*x* ^{2} − 4*x* +1

Plug in −1 for *x* :

*f* (−1) = 2(−1)^{2} − 4(−1) + 1

Simplify:

*f* (−1) = 2(1) + 4 + 1 = 2 + 4 + 1 = 7

Therefore line *l* intersects the function at (−1, 7).

Plug in 2 for *x* :

*f* (2) = 2(2)^{2} − 4(2) + 1

Simplify:

*f* (2) = 2(4) − (8) + 1 = 8 − 8 + 1 = 1

Therefore line *l* intersects the function at (2, 1). Now we find the slope of the line containing these two points.

The general equation of a parabola in the *xy* -plane is *y* = *a* (*x* − *h* )^{2} + *k* , in which (*h* , *k* ) is the vertex. Now let”s express each choice in precisely this form.

(A) *y* = (*x* − 3)^{2} + 2 *y* = 1(*x* − 3)^{2} + 2 *a* = 1, *h* = 3, *k* = 2

(B) *y* = 2(*x* − 3)^{2} *y* = 2(*x* − 3)^{2} + 0*a* = 2, *h* = 3, *k* = 0

(C) *y* = 2*x* ^{2} − 3 *y* = 2(*x* − 0)^{2} − 3*a* = 2, *h* = 0, *k* = −3

(D) *y* = 3*x* ^{2} + 2 *y* = 3(*x* − 0)^{2} + 2*a* = 3, *h* = 0, *k* = 2

**Algebra (linear relationships) MEDIUM**

We are told that the temperature varies linearly with altitude, so if *y* represents the temperature (in °C) and *x* represents altitude (in km), these variables are related by the equation *y* = *mx* + *b* , where *m* (the slope) and *b* (the *y* -intercept) are constants.

We are given two points on this line: (50 km, 10°) and (80 km, −80°). We can use these points to find the slope, *m* :

Recall that the slope of a linear relationship is the “unit rate of change.” In other words, the slope of −3 means that the temperature declines by 3° for every 1 km of additional altitude. Since we want the altitude at which the temperature is −50°, we want the value of *x* such that (*x* , −50°) is on this line. To find *x* , we can simply use the slope formula again, using either of the other two points: Slope formula using (50, 10) and (*x* , −50):

Multiply by 50 − *x* :

60 = −3(50 − *x* )

Any point that intersects the *y* -axis has an *x* -value of 0. So, to find point *A* , plug in 0 for *x* and solve for *y* :

*y* = 2*x* ^{2} − 16*x* + 14

Plug in 0 for *x* :

*y* = 2(0)^{2} − 16(0) + 14 = 14

Any point that intersects the *x* -axis has a *y* -value of 0. So, to find points *B* and *C* , plug in 0 for *y* and solve for *x* :

*y* = 2*x* ^{2} − 16*x* + 14

Substitute 0 for *y* :

0 = 2*x* ^{2} − 16*x* + 14

Divide by 2:

0 = *x* ^{2} − 8*x* + 7

Factor:

0 = (*x* − 7)(*x* − 1)

Use the Zero Product Property:

*x* = 7 and *x* = 1

If we connect these three points, we get a triangle with a height of 14 (from *y* = 0 to *y* = 14) and a base of 6 (from *x* = 1 to *x* = 7).

Use the triangle area formula *bh* :

Simplify:

*y* = (2)^{2} (-3)^{2} = (4)(9) = 36

Therefore the *y* -intercept is at (0, 36).

To find the *x* -intercepts, set *y* = 0:

0 = (*x* + 2)^{2} (*x* − 3)^{2}

The slope of this line is *k* − 1 and its *y* -intercept is − *k* . If *k* > 2, then *k* − 1 > 1, and − *k* < −2. In other words, the slope of the line is greater than 1 and the *y* -intercept is less than −2. The only graph with these features is the one in choice (B).

In order for this system of equations to have at least one solution, these two lines must have an intersection. How can two lines with the same slope intersect?

(B) *The total number of retail stores increased by 50% from 2005 to 2012* . True or false? According to the scatterplot, in 2005 there were 3 stores corresponding to the three dots above 2005. In 2012 there were 6 stores corresponding to the 6 dots above 2012. This is a percent increase of

FALSE

(C) *The total revenue for all stores in 2012 is more than three times the total revenue from all stores in 2004* . True or false? In 2004, there were 3 stores with an average revenue per store of approximately $250,000. Therefore the total revenue in 2004 was approximately 3 × $250,000 = $750,000. In 2012, there were 6 stores with an average revenue per store of approximately $650,000. Therefore the total revenue in 2012 was approximately 6 × $650,000 = $3,900,000. Since $3,900,000 is more than three time $750,000, this statement is TRUE.

If the Giants” win-loss is 2:3, then they won 2*n* games and lost 3*n* games, where *n* is some unknown integer. (For instance, perhaps they won 2 games and lost 3, in which case *n* = 1, or perhaps they won 20 games and lost 30, in which case *n* = 10, etc.) This means that the total number of games they played is 2*n* + 3*n* = 5*n* . Since they won 120 games,

5*n* = 120

Divide by 5:

*n* = 24

Therefore they won 2*n* = (2)(24) = 48 games and lost 3*n* = (3)(24) = 72 games, and so they lost 72 − 48 = 24 more games than they won.

We might begin by plugging in a number for *p* . Let”s say *p* = 120 cells to start. We are told that after one hour the population decreased by . Since of 120 is 40, the population decreased by 40 and the population was then 120 − 40 = 80 cells. In the second hour, the population *increased* by 40%. Increasing a number by 40% is equivalent to it by 1.40 (because it becomes 140% of what it was), so the population was then 80(1.40) = 112 cells. In the third hour, the population *increased* by 50%, so it became 112(1.50) = 168 cells.

Substituting *p* = 120 into each of the answer choices yields (A) 1.3*p* = 1.3(120) = 156, (B) 1.4*p* = 1.4(120) = 168, (C) 1.5*p* = 1.5(120) = 180, and (D) 1.6*p* = 1.6(120) = 192. Therefore the answer is (B).

Let *R* = the number of red marbles, *W* = the number of white marbles, and *B* = the number of blue marbles. If the jar contains twice as many red marbles as white marbles, then *R* = 2*W* . If the jar contains three times as many white marbles as blue marbles, then *W* = 3*B* . We can substitute numbers to these equations to solve the problem. Let”s say *B* = 10. This means there are 3(10) = 30 white marbles and 2(30) = 60 red marbles. The total number of marbles is therefore 10 + 30 + 60 = 100, and the number of non-red marbles is therefore 10 + 30 = 40 marbles, so the probability that the marble is *not* red is .

Since one-third of the soccer players also run track, we must put in the overlapping region between soccer and track, and therefore the number who play only soccer is . Likewise, since one-half of the athletes who run track also play soccer, we must put in the overlapping region, and therefore the number of athletes who only run track is .

Sincer there are 60 athletes in total:

2*s* + 3*t* = 180

The number of soccer players who run track must equal the number of track athletes who play soccer:

**Special Topics (trigonometry) HARD**

The statement indicates that *x* is an angle in quadrant II, where the cosine is negative. Let”s draw this situation on the unit circle so we can visualize it. (We don”t want to confuse the *angles* called *x* and *y* in the problem with the *x* -coordinates and *y* -coordinates in the *xy* -plane. For this reason, let”s label the terminal rays for the angles “angle *x* ” and “angle *y* .”) Recall that the cosine of any angle is the *x* -coordinate of the point on the unit circle that corresponds to that angle. If cos *x* = *a* , then *a* is the *x* -coordinate of the point on the unit circle that corresponds to “angle *x* ,” as shown in the diagram.

Now notice that, since *a* is a negative number, −*a* (that, is, the *opposite* of *a* ), is a *positive* number. More specifically, it is the reflection of the point labeled *a* over the *x* -axis, as shown in the diagram. Now, if cos *y* = −*a* , then “angle *y* ” corresponds to a point on the unit circle with an *x* -coordinate of −*a* . There are two possible locations for this point on the circle, and both are shown in the diagram above. Notice that one of these angles is the reflection of “angle *x* ” over the *y* -axis. This is the supplement of “angle *x* ,” that is, π − *x* . The other is the reflection of “angle *x* ” over the origin, that is *x* + π. Therefore, the correct answer is (B).

Alternately, we could use the calculator to solve this problem by process of elimination. We can choose a value of “angle *x* ” between π/2 and π. (In radian mode this is an angle between 1.57 and 3.14, and in degree mode it is an angle between 90° and 180°.) Let”s pick “angle *x* ” to be 2 radians (about 115°). According to the calculator, cos(2) = −.416. Therefore, cos *y* must equal .416. Now we can substitute *x* = 2 into all of the choices and see which angle has a cosine of .416.

(A) cos(2 + 2π *)* = −.416

(B) cos(2 + π) = .416

(C) cos(2 + π/2) = −.909

(D) cos(−2 + 2π) = −.416

Therefore the correct answer is (B).

What percentage of *those* are under 40? The answer is in the first row of the table (18 to 39): 917 of these Approve and 204 of these Disapprove. Therefore 917 + 204 = 1,121 of those showing an opinion are under 40 years of age.

Age 40 to 64:

1,040 out of 1,644 approve (64%)

Age 65 and older:

604 out of 1,139 approve (53%)

The approval rate increases and then decreases with age, so (A) is not correct.

Age 18 to 39:

Age 40 to 64:

502 out of 1,644 disapprove (31%)

CASE 1:

*m* ^{2} = 4 and *n* ^{2} = 36

80 phones sold for $98

40 phones sold for $110

20 phones sold for $120

62 phones sold for $140

38 phones sold for $162

We don”t have to actually write out the prices of all 240 phones to find the median price. We can divide any set of 240 numbers, in ascending order, into two sets of 120 numbers. The median is in the middle of these, so it is the average of the 120th and 121st numbers. Since the first two categories account for 40 + 80 = 120 of these numbers, the 120th number in the set is $110, and the 121st number in the set is in the next higher category, $120. The median price is therefore ($110 + $120)/2 = $115.

Since the logo has a height-to-length

ratio of 5:8:

Cross multiply:

5*x* = 32

Divide by 5:

*x* = 6.4

Since the banner is 20 feet long, there are 20 − 6.4 = 13.6 feet in total for the side margins. If the logo is centered, then each margin is half this length, 13.6 ÷ 2 = 6.8 feet.

__38__ . **25**

**Problem Solving (extended thinking) HARD**

The banner has dimensions of 20 feet by 4 feet, so its area is 20 × 4 = 80 square feet. If the company charges $1.20 per square foot for the banner material, this cost is 80 × $1.20= $96. Based on the logo dimensions we determined in the previous problem, the area of the logo is 4 × 6.4 = 25.6 square feet. If the company charges $2.50 per square foot for the logo, the cost per printed logo is 25.6 × $2.50 = $64.

If the company charges a fixed cost of $32 per banner, then the total cost of a banner with ONE logo would be $96 + $64 + $32 = $192. The total cost of a banner with TWO logos would be $96 + $64 + $64 + $32 = $256.

We can calculate the percent savings with the “percent change” formula, since we are considering a “change” from the more expensive banner to the less expensive banner.

Therefore the percent savings is 25(%).

In this essay, Steven Pinker examines the “moral panics” surrounding new forms of media and the supposed cognitive and moral decline they cause. His essay provides a measure of balance to our modern discussions of social media and instantaneous digital information. He supports his thesis, that “such panics often fail reality checks,” with examples dating back as far as the 1950s, logical analysis, vibrant illustrative images, and touches of humor. He provides historical and scientific context for his claims and effectively encapsulates the broad misconceptions that cultural critics have about the relationship between modern media and the human brain. Although his argument could have been bolstered with more specific scientific support, his essay as a whole effectively argues for a reprieve from the hysteria about intellectual and moral decline allegedly caused by Twitter and Facebook.

Pinker makes use of “reductio ad absurdum,” or indirect proof, to make his case. This technique proceeds by arguing that if the point to be refuted were true, it would lead necessarily to a contradiction, and therefore it cannot be true. For instance, Pinker hints at this logical technique in the second paragraph: “When comic books were accused of turning juveniles into delinquents in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline.” Here, Pinker is suggesting that sociological and psychological evidence refutes claims of social decline.

He uses reductio ad absurdum even more explicitly in the third paragraph: “If electronic media were hazardous to intelligence, the quality of science would be plummeting. Yet discoveries are multiplying like fruit flies, and progress is dizzying. Other activities in the life of the mind, like philosophy, history and cultural criticism, are likewise flourishing.” Unfortunately, Pinker does not provide substantial evidence to bolster these claims. He fails to address the common counterclaim that much of the “science” published on the Internet is flimsy, and the “cultural criticism” lazy.

Pinker then goes on to outline a basic lesson in human information processing, in an attempt to ground his argument in science. To Pinker, the claim that “information can change the brain” is facile (“it”s not as if the information is stored in the pancreas”) and misleading (“the existence of neural plasticity does not mean the brain is a blob of clay pounded into shape by experience”). Rather, Pinker suggests, “the effects of experience are highly specific to the experiences themselves. … Music doesn”t make you better at math; conjugating Latin doesn”t make you more logical; brain-training games don”t make you smarter.” Unfortunately, Pinker here seems to mistake assertion for argumentation. He is directly contradicting the claims of thousands of music and Latin teachers, as well as dozens of Lumosity commercials. But he is only gainsaying. Here again, we might expect some data to support his points.

Next, Pinker attempts to refute cultural critics by drawing analogies between their reasoning and the faulty reasoning of “primitive peoples” who believe that “eating fierce animals will make them fierce.” He likens this to the thinking of modern observers who believe that “reading bullet points and Twitter postings turns your thoughts into bullet points and Twitter postings.” But of course just because one line of reasoning parallels another does not mean that both are equally incorrect. Here again, Pinker”s argument would benefit from information about the actual cognitive effects of reading Twitter feeds.

Next, Pinker provides a qualification: “Yes, the constant arrival of information packets can be distracting or addictive, especially to people with attention deficit disorder.” But here again, even in conceding a point, Pinker doesn”t quite offer the information a reader might want: How significant is this distraction or addiction, and does it have any harmful long-term effects? We don”t get this information from Pinker, but we do get some practical advice: “Turn off e-mail or Twitter when you work …” We get even more substantial advice in the next paragraph: to cultivate “intellectual depth,” we must avail ourselves of “special institutions, which we call universities” and engage in “analysis, criticism, and debate.” But why, a reader might wonder, should we moderate our use of electronic media if it doesn”t have any real harmful effects?

Finally, Pinker ends with a broader perspective and a note of hope: “the Internet and information technologies are helping us manage, search, and retrieve our collective intellectual output. … Far from making us stupid, these technologies are the only things that will keep us smart.” Perhaps Pinker is right, but his argument would be stronger with more substantial quantitative evidence and more direct refutation of our real concerns about how the Internet might be changing our brains.

**Scoring**

**Reading—8 (both readers gave it a score of 4)**

This response demonstrates extremely thorough comprehension of Pinker”s essay through skillful use of summary, paraphrase, and direct quotations. The author summarizes Pinker”s central thesis and modes of persuasion (*His thesis, that “such panics often fail reality checks,” is supported with examples dating back as far as the 1950s, careful logical analysis, vibrant illustrative images, and touches of humor* ) and shows a clear understanding of Pinker”s supporting ideas and overall tone (*He provides historical and scientific context for his claims and effectively encapsulates the broad misconceptions that cultural critics have about the relationship between modern media and the human brain. … Pinker ends with a broader perspective and a note of hope* ). Each quotation is accompanied by insightful commentary that demonstrates that this author thoroughly understands Pinker”s central and secondary ideas, and even recognizes when Pinker seems occasionally to fall short of his own purpose.

**Analysis—8 (both readers gave it a score of 4)**

This response provides a thoughtful and critical analysis of Pinker”s essay and demonstrates a sophisticated understanding of the analytical task. The author has identified Butler”s primary modes of expression (*logical analysis, vibrant illustrative images, and touches of humor* ) and has even provided a detailed examination of Pinker”s preferred logical method, reductio ad absurdum, with a discussion of several examples. Perhaps even more impressively, the author indicates where Pinker”s evidence falls short, providing critical analysis and suggesting alternatives (*Unfortunately, Pinker does not provide substantial evidence to bolster these claims. He doesn”t address the common counterclaim that much of the “science” published on the Internet is flimsy, and the “cultural criticism” lazy. … Pinker here seems to mistake assertion for argumentation. … Here again, Pinker”s argument would benefit from information about the actual cognitive effects of reading Twitter feeds* ). Overall, the author”s analysis of Pinker”s essays demonstrates a thorough understanding not only of the rhetorical task that Pinker has set for himself, but also the means by which it is best accomplished.

**Writing—8 (both readers gave it a score of 4)**

This response shows a masterful use of language, sentence structure to establish a clear and insightful central claim (*Although his argument could have been bolstered with more specific scientific support, his essay as a whole effectively argues for a reprieve from the hysteria about intellectual and moral decline allegedly caused by Twitter and Facebook* ). The response maintains a consistent focus on this central claim and supports it with a well-developed and cohesive analysis of Pinker”s essay. The author demonstrates effective verb choice (*effectively encapsulates the broad misconceptions. … He likens this to the thinking of modern observers* ), strong grasp of relevant analytical terms, like *reduction ad absurdum, facile, sociological and psychological evidence, counterclaim, assertion, argumentation* , and *gainsaying* . The response is well-developed, progressing from general claim to specific analysis to considered evaluation. Largely free from grammatical error, this response demonstrates strong command of language and proficiency in writing.
