READING DIRECTIONS: Each passage or pair of passages below is followed by a number of questions. After reading each passage or pair, choose the best answer to each question based on what is stated or implied in the passage or passages and in any accompanying graphics (such as a table or graph).

Questions 1-11 are based on the following passage. This passage is adapted from Emily Anthes, Frankenstein’s Cat. ©2013 by Emily Anthes.

When scientists first learned how to edit the genomes of animals, they began to imagine all the ways they could use this new power. Creating brightly colored novelty pets was not a high priority. Instead, most researchers envisioned far more consequential applications, hoping to create genetically engineered animals that saved human lives. One enterprise is now delivering on this dream. Welcome to the world of “pharming,” in which (10) simple genetic tweaks turn animals into living pharmaceutical factories. Many of the proteins that our cells crank out naturally make for good medicine. Our bodies’ own enzymes, hormones, clotting factors, and antibodies are commonly used to treat cancer, diabetes, autoimmune diseases, and more. The trouble is that it’s difficult and expensive to make these compounds on an industrial scale, and as a result, patients can face shortages of the medicines they need.

Dairy (20) animals, on the other hand, are expert protein producers, their udders swollen with milk. So the creation of the first transgenic animals—first mice, then other species—in the 1980s gave scientists an idea: What if they put the gene for a human antibody or enzyme into a cow, goat, or sheep? If they put the gene in just the right place, under the control of the right molecular switch, maybe they could engineer animals that produced healing human proteins in their milk. Then doctors could collect medicine by the bucketful. (30) Throughout the 1980s and ’90s, studies provided proof of principle, as scientists created transgenic mice, sheep, goats, pigs, cattle, and rabbits that did in fact make therapeutic compounds in their milk. At first, this work was merely gee-whiz, scientific geekery, lab-bound thought experiments come true. That all changed with ATryn, a drug produced by the Massachusetts firm GTC Biotherapeutics.

ATryn is antithrombin, an anticoagulant that can be used to (40) prevent life-threatening blood clots. The compound, made by our liver cells, plays a key role in keeping our bodies clot-free. It acts as a molecular bouncer, sidling up to clot-forming compounds and escorting them out of the bloodstream. But as many as 1 in 2,000 Americans are born with a genetic mutation that prevents them from making antithrombin. These patients are prone to clots, especially in their legs and lungs, and they are at elevated risk of suffering from fatal complications during surgery and (50) childbirth. Supplemental antithrombin can reduce this risk, and GTC decided to try to manufacture the compound using genetically engineered goats. To create its special herd of goats, GTC used microinjection, the same technique that produced GloFish and AquAdvantage salmon. The company’s scientists took the gene for human antithrombin and injected it directly into fertilized goat eggs. Then they implanted the eggs in the wombs of female goats.

(60) When the kids were born, some of them proved to be transgenic, the human gene nestled safely in their cells. The researchers paired the antithrombin gene with a promoter (which is a sequence of DNA that controls gene activity) that is normally active in the goat’s mammary glands during milk production. When the transgenic females lactated, the promoter turned the transgene on and the goats’ udders filled with milk containing antithrombin. All that was left to do was to collect the milk, and extract and purify (70) the protein. Et voilà—human medicine! And, for GTC, liquid gold. ATryn hit the market in 2006, becoming the world’s first transgenic animal drug. Over the course of a year, the “milking parlors” on GTC’s 300-acre farm in Massachusetts can collect more than a kilogram of medicine from a single animal.


The primary purpose of the passage is to

  1. present the background of a medical breakthrough.
  2. evaluate the research that led to a scientific discovery.
  3. summarize the findings of a long-term research project.
  4. explain the development of a branch of scientific study.


The author’s attitude toward pharming is best described as one of

  1. apprehension.
  2. ambivalence.
  3. appreciation.
  4. astonishment.


As used in line 20, “expert” most nearly means

  1. knowledgeable.
  2. professional.
  3. capable.
  4. trained.


What does the author suggest about the transgenic studies done in the 1980s and 1990s?

  1. They were limited by the expensive nature of animal research.
  2. They were not expected to yield products ready for human use.
  3. They were completed when an anticoagulant compound was identified.
  4. They focused only on the molecular properties of cows, goats, and sheep


Which choice provides the best evidence for the answer to the previous question?

  1. Lines 16-19 (“The trouble… need”)
  2. Lines 25-29 (“If they… milk”)
  3. Lines 35-36 (“At first… true”)
  4. Lines 37-40 (“That all… clots”)


According to the passage, which of the following is true of antithrombin?

  1. It reduces compounds that lead to blood clots.
  2. It stems from a genetic mutation that is rare in humans.
  3. It is a sequence of DNA known as a promoter.
  4. It occurs naturally in goats’ mammary glands.


Which choice provides the best evidence for the answer to the previous question?

  1. Lines 12-16 (“Many… more”)
  2. Lines 42-44 (“It acts… bloodstream”)
  3. Lines 44-46 (“But as… antithrombin”)
  4. Lines 62-65 (“The researchers… production”)


Which of the following does the author suggest about the “female goats” mentioned in line 59?

  1. They secreted antithrombin in their milk after giving birth.
  2. Some of their kids were not born with the antithrombin gene.
  3. They were the first animals to receive microinjections.
  4. Their cells already contained genes usually found in humans.


The most likely purpose of the parenthetical information in lines 63-64 is to

  1. illustrate an abstract concept.
  2. describe a new hypothesis.
  3. clarify a claim.
  4. define a term.


The phrase “liquid gold” (line 71) most directly suggests that

  1. GTC has invested a great deal of money in the microinjection technique.
  2. GTC’s milking parlors have significantly increased milk production.
  3. transgenic goats will soon be a valuable asset for dairy farmers.
  4. ATryn has proved to be a financially beneficial product for GTC.

WRITING & LANGUAGE 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.

Research on regional variations in English-language use has not only yielded answers to such (1) life-altering questions as how people in different parts of the United States refer to carbonated beverages (“soda”? “pop”? “coke”?) (2) it also illustrates how technology can change the very nature of research. While traditional, human-intensive data collection (3) has all but disappeared in language studies, the explosion of social media has opened new avenues for investigation. Perhaps the epitome of traditional methodology is the Dictionary of American Regional English, colloquially known as DARE. Its fifth and final alphabetical volume—ending with “zydeco”—released in 2012, the dictionary represents decades of arduous work. Over a six-year period from 1965 to 1970, university graduate students conducted interviews in more than a thousand communities across the nation. Their goal was to determine what names people used for such everyday objects and concepts as a submarine sandwich…

…(a “hero” in New York City but a “dagwood” in many parts of Minnesota, Iowa, and Colorado) and a heavy rainstorm (variously a “gully washer,” “pour-down,” or “stump mover”). [5] The work that dictionary founder Frederic G. Cassidy had expected to be finished by 1976 was not, in fact, completed in his lifetime. [6] The wait did not dampen enthusiasm among (4) scholars. Scholars consider the work a signal achievement in linguistics. (5) Not all research into regional English varieties (6) requires such time, effort, and resources, however. Today’s researchers have found that the veritable army of trained volunteers traveling the country conducting face-to-face interviews can sometimes be (7) replaced by another army the vast array of individuals volunteering details about their lives—and, inadvertently, their language—through social media. Brice Russ of Ohio State University, for example, has employed software to sort through postings on one social media (8) cite in search of particular words and phrases of interest as well as the location from which users are posting. From these data,…
