For those of us who wish to preserve the planet’s diversity of species, high-tech, chemically assisted agriculture is an environmentalist’s best friend. That’s right. Soaring growth in human population threatens to destroy most of the world’s remaining rainforests, wetlands, and mountain ecosystems, drastically reducing species diversity. Despite advances in chemical-free farming techniques, overreliance on these practices will result in the plowing down of forests to feed a global population that is estimated to reach 9.6 billion people by 2050. Environmentalists must face the fact that unless high-yield crop varieties, pesticides, and fertilizers are widely used in developing nations, the world’s food supply will be outstripped by spiraling demand. This will mean more forests falling under the plow. I couldn’t agree more that it’s crucial to step up agricultural productivity to feed a spiraling global population. My quarrel is with how to intensify agriculture, not whether it should be intensified. The paramount concern must be to increase crop yields in environmentally sensitive ways that protect human health and the soil and water that are agriculture’s very foundation. Heavy use of agrochemicals can bring high yields in the short run, but the cumulative damages may be considerable. Those of us whose research demonstrates that resource-conserving farming practices can be just as productive as the chemical-intensive kind contend that the goal should be efficient use of chemicals, not wide use.
The author of Passage 1 uses the phrase 'That's right' in order to:
- A. acknowledge that a claim may be surprising
- B. confirm that a prediction was accurate
- C. concede that a criticism has merit
- D. emphasize that a debate has been settled
Correct Answer & Rationale
Correct Answer: A
The phrase "That's right" is used to acknowledge a statement or claim, often indicating that it may be unexpected or surprising to the audience. This aligns with option A, as it highlights an awareness of the potential shock value of the claim. Option B is incorrect because confirming a prediction implies certainty and agreement with a prior statement, which is not the intent of the phrase. Option C misinterprets the phrase's meaning; conceding a criticism suggests acceptance of fault, which does not fit the context. Option D also misses the mark, as emphasizing a settled debate would imply finality, whereas "That's right" suggests an ongoing dialogue rather than closure.

When the author writes that Chilesaurus diegosuarezi “should have been a meat-eater,†she most likely means that the species:
- A. would have been healthier if it had eaten meat
- B. would have grown even larger if it had eaten meat
- C. had the head, neck, and teeth of a meat-eater
- D. had body features similar to those of its meat-eating relative
Correct Answer & Rationale
Correct Answer: D
The statement implies that Chilesaurus diegosuarezi possesses physical characteristics akin to those of carnivorous dinosaurs. Option D accurately reflects this by highlighting that its body features resemble those of its meat-eating relatives, suggesting an evolutionary expectation based on morphology. Option A incorrectly assumes a health benefit from a meat-based diet, which is not the focus of the author's observation. Option B speculates on size without evidence, as diet does not directly correlate with growth potential in this context. Option C, while partially true about its head and teeth, overlooks the broader comparison to body features, making D the most comprehensive choice.

Which of the following, if true, would most challenge the 'implication' mentioned in the fourth sentence? 'Some experts reject the implication that Çatalhöyük’s farmers cultivated distant fields, since large quantities of grain would have had to be transported.'
- A. Çatalhöyük's farmers obtained through trade the wheat and barley that Rosen analyzed.
- B. Çatalhöyük's farmers understood the impact of soil conditions on crop productivity.
- C. Çatalhöyük's farmers shared wheat and barley fields with neighboring villages.
- D. Çatalhöyük's farmers used wood that deteriorated in the damp environment.
Correct Answer & Rationale
Correct Answer: A
Option A directly challenges the implication that farmers at Çatalhöyük cultivated distant fields by suggesting they obtained the grains through trade instead. This undermines the need for transporting large quantities of grain from faraway locations, thus supporting the idea that local cultivation was not necessary. Option B focuses on soil conditions but does not address the transportation issue, leaving the original implication intact. Option C implies shared resources with neighbors but does not clarify whether these fields were local or distant, failing to challenge the transportation concern. Option D discusses environmental factors unrelated to the cultivation and transport of grain, making it irrelevant to the implication.

In sentence 13, the narrator most likely uses the image of 'a tightly woven fruit basket' to suggest that the rain is:
- A. a physical challenge that must be endured
- B. falling so heavily that she can barely see through it
- C. a reminder of the weather in harvest season
- D. important because it allows crops to survive
Correct Answer & Rationale
Correct Answer: A
The image of "a tightly woven fruit basket" conveys the idea of resilience and endurance, suggesting that the rain is a challenge that must be faced. This metaphor implies that just like a tightly woven basket holds its contents together despite external pressures, the narrator must endure the rain's intensity. Option B misinterprets the imagery; while heavy rain can obscure vision, the metaphor focuses more on endurance than visibility. Option C incorrectly links the rain to harvest season, which is not implied in the context. Option D, while true about rain's importance for crops, does not capture the struggle suggested by the basket imagery.

Which choice best describes the overall structure of the passage?
- A. The passage examines the effect of decreased environmental awareness on some animals' predation risk and then describes the strategies those animals use to increase their environmental awareness while sleeping.
- B. The passage distinguishes between bihemispheric slow-wave sleep (BSWS) and unihemispheric slow-wave sleep (USWS) and then explains why USWS is less beneficial than BSWS for animals such as mallards and penguins.
- C. The passage discusses the advantages for some animals of sleeping at the center of a group and then questions whether those advantages extend to colonial birds.
- D. The passage provides an extended description of how mallards typically sleep and then compares sleeping behaviors in mallards to those in penguins.
Correct Answer & Rationale
Correct Answer: C
Choice C accurately captures the passage's structure, which begins by exploring the benefits of group sleeping for certain animals and then raises a critical inquiry regarding the applicability of these benefits to colonial birds. This dual focus on advantages and questioning reflects a balanced examination of the topic. Option A misrepresents the content by suggesting a focus on predation risk and strategies for environmental awareness, which is not the main theme. Option B incorrectly centers on a comparison of sleep types, neglecting the broader discussion of group sleeping benefits. Option D inaccurately emphasizes a detailed comparison of mallards and penguins, rather than the initial exploration of group sleeping advantages.
