Questions 1-11 are based on the following passage.

Whey to Go
Greek yogurt—a strained form of cultured yogurt—has grown enormously in popularity in the United States since it was first introduced in the country in the late 1980s.
From 2011 to 2012 alone, sales of Greek yogurt in the US increased by 50 percent. The resulting increase in Greek yogurt production has forced those involved in the business to address the detrimental effects that the yogurt-making process may be having on the environment. Fortunately, farmers and others in the Greek yogurt business have found many methods of controlling and eliminating most environmental threats. Given these solutions as well as the many health benefits of the food, the advantages of Greek yogurt 1 outdo the potential drawbacks of its production.

[1] The main environmental problem caused by the production of Greek yogurt is the creation of acid whey as a by-product. [2] Because it requires up to four times more milk to make than conventional yogurt does, Greek yogurt produces larger amounts of acid whey, which is difficult to dispose of. [3] To address the problem of disposal, farmers have found a number of uses for acid whey. [4] They can add it to livestock feed as a protein 2 supplement, and people can make their own Greek-style yogurt at home by straining regular yogurt. [5] If it is improperly introduced into the environment, acid-whey runoff  3 can pollute waterways, depleting the oxygen content of streams and rivers as it decomposes. [6] Yogurt manufacturers, food 4 scientists; and government officials are also working together to develop additional solutions for reusing whey. 5

6 Though these conservation methods can be costly and time-consuming, they are well worth the effort. Nutritionists consider Greek yogurt to be a healthy food: it is an excellent source of calcium and protein, serves 7 to be a digestive aid, and 8 it contains few calories in its unsweetened low- and non-fat forms.  Greek yogurt is slightly lower in sugar and carbohydrates than conventional yogurt is. 9 Also, because it is more concentrated, Greek yogurt contains slightly more protein per serving, thereby helping people stay...

10 satiated for longer periods of time. These health benefits have prompted Greek yogurt’s recent surge in popularity. In fact, Greek yogurt can be found in an increasing number of products such as snack food and frozen desserts. Because consumers reap the nutritional benefits of Greek yogurt and support those who make and sell 11 it, therefore farmers and businesses should continue finding safe and effective methods of producing the food.

Questions 12-22 are based on the following passage and supplementary material.

Dark Snow
Most of Greenland’s interior is covered by a thick layer of ice and compressed snow known as the Greenland Ice Sheet. The size of the ice sheet fluctuates seasonally: in summer, average daily high temperatures in Greenland can rise to slightly above 50 degrees Fahrenheit, partially melting the ice; in the winter, the sheet thickens as additional snow falls, and average daily low temperatures can drop 20 to as low as 20 degrees.

---

12
Which choice most accurately and effectively represents the information in the graph?

Typically, the ice sheet begins to show evidence of thawing in late 13 summer. This follows several weeks of higher  temperatures. 14 For example, in the summer of 2012, virtually the entire Greenland Ice Sheet underwent thawing at or near its surface by mid-July, the earliest date on record. Most scientists looking for the causes of the Great Melt of 2012 have focused exclusively on rising temperatures. The summer of 2012 was the warmest in 170 years, records show. But Jason 15 Box, an associate professor of geology at Ohio State believes that another factor added to the early 16 thaw; the “dark snow” problem.

13
Which choice most effectively combines the two sentences at the underlined portion?

14

16

According to Box, a leading Greenland expert, tundra fires in 2012 from as far away as North America produced great amounts of soot, some 17 of it drifted over Greenland in giant plumes of smoke and then 18 fell as particles onto the ice sheet. Scientists have long known that soot particles facilitate melting by darkening snow and ice, limiting 19 it’s ability to reflect the Sun’s rays. As Box explains, “Soot is an extremely powerful light absorber. It settles over the ice and captures the Sun’s heat.” The result is a self-reinforcing cycle. As the ice melts, the land and water under the ice become exposed, and since land and water are darker than snow, the surface absorbs even more heat, which 20 is related to the rising temperatures.

19

20
Which choice best completes the description of a self-reinforcing cycle?

[1] Box’s research is important because the fires of 2012 may not be a one-time phenomenon. [2] According to scientists, rising Arctic temperatures are making northern latitudes greener and thus more fire prone. [3] The pattern Box observed in 2012 may repeat 21 itself again, with harmful effects on the Arctic ecosystem. [4] Box is currently organizing an expedition to gather this crucial information. [5] The next step for Box and his team is to travel to Greenland to perform direct sampling of the ice in order to determine just how much the soot is contributing to the melting of the ice sheet. [6] Members of the public will be able to track his team’s progress—and even help fund the expedition—through a website Box has created. 22

To make this paragraph most logical, sentence 4 should be placed

Questions 23-33 are based on the following passage.

Coworking: A Creative Solution
When I left my office job as a website developer at a small company for a position that allowed me to work full-time from home, I thought I had it made: I gleefully traded in my suits and dress shoes for sweatpants and slippers, my frantic early-morning bagged lunch packing for a leisurely midday trip to my refrigerator. The novelty of this comfortable work-from-home life, however, 23 soon got worn off quickly. Within a month, I found myself feeling isolated despite having frequent email and  instant messaging contact with my colleagues. Having become frustrated trying to solve difficult problems, 24 no colleagues were nearby to share ideas. It was during this time that I read an article 25 into coworking spaces.

The article, published by Forbes magazine, explained that coworking spaces are designated locations that, for a fee, individuals can use to conduct their work. The spaces are usually stocked with standard office 26 equipment, such as photocopiers, printers, and fax machines. 27 In these locations, however, the spaces often include small meeting areas and larger rooms for hosting presentations. 28 The cost of  launching a new coworking business in the United States is estimated to be approximately $58,000.

The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?

What most caught my interest, though, was a quotation from someone who described coworking spaces as “melting pots of creativity.” The article refers to a 2012 survey in which 29 64 percent of respondents noted that coworking spaces prevented them from completing tasks in a given time. The article goes on to suggest that the most valuable resources provided by coworking spaces are actually the people 30 whom use them.

At this point, the writer wants to add specific information that supports the main topic of the paragraph.

Which choice most effectively completes the sentence with relevant and accurate information based on the graph above?

30

[1] Thus, even though I already had all the equipment I needed in my home office, I decided to try using a coworking space in my city. [2] Because I was specifically interested in coworking’s reported benefits related to creativity, I chose a facility that offered a bright, open work area where I wouldn’t be isolated. [3] Throughout the morning, more people appeared. [4] Periods of quiet, during which everyone worked independently, were broken up occasionally with lively conversation. 31

I liked the experience so much that I now go to the coworking space a few times a week. Over time, I’ve gotten to know several of my coworking 32 colleagues: another website developer, a graphic designer, a freelance writer, and several mobile app coders. Even those of us who work in disparate fields are able to 33 share advice and help each other brainstorm. In fact, it’s the diversity of their talents and experiences that makes my coworking colleagues so valuable.

The writer wants to add the following sentence to the paragraph.

After filling out a simple registration form and taking a quick tour of the facility, I took a seat at a table and got right to work on my laptop.

Questions 34-44 are based on the following passage.

The Consolations of Philosophy
Long viewed by many as the stereotypical useless major, philosophy is now being seen by many students and prospective employers as in fact a very useful and practical major, offering students a host of transferable skills with relevance to the modern workplace. 34 In broad terms, philosophy is the study of meaning and the values underlying thought and behavior. But 35 more pragmatically, the discipline encourages students to analyze complex material, question conventional beliefs, and express thoughts in a concise manner.

Because philosophy 36 teaching students not what to think but how to think, the age-old discipline offers consistently useful tools for academic and professional achievement. 37 A 1994 survey concluded that only 18 percent of American colleges required at least one philosophy course. 38 Therefore, between 1992 and 1996, more than 400 independent philosophy departments were eliminated from institutions.

37
Which choice most effectively sets up the information that follows?

38

More recently, colleges have recognized the practicality and increasing popularity of studying philosophy and have markedly increased the number of philosophy programs offered. By 2008 there were 817 programs, up from 765 a decade before. In addition, the number of four-year graduates in philosophy has grown 46 percent in a decade. Also, studies have found that those students who major in philosophy often do better than students from other majors in both verbal reasoning and analytical 39 writing. These results can be measured by standardized test scores. On the Graduate Record Examination (GRE), for example, students intending to study philosophy in graduate school 40 has scored higher than students in all but four other majors.

These days, many 41 student’s majoring in philosophy have no intention of becoming philosophers; instead they plan to apply those skills to other disciplines. Law and business specifically benefit from the complicated theoretical issues raised in the study of philosophy, but philosophy can be just as useful in engineering or any field requiring complex analytic skills. 42 That these skills are transferable across professions....

At this point, the writer is considering adding the following sentence.

The ancient Greek philosopher Plato, for example,wrote many of his works in the form of dialogues.

Should the writer make this addition here?

.... 43 which makes them especially beneficial to twenty-first-century students. Because today’s students can expect to hold multiple jobs—some of which may not even exist yet—during 44 our lifetime, studying philosophy allows them to be flexible and adaptable. High demand, advanced exam scores, and varied professional skills all argue for maintaining and enhancing philosophy courses and majors within academic institutions.
