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 2 would most likely respond to the statement in the fifth sentence of Passage 1 ('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') by arguing that:
- A. industrialized nations pose a greater threat to the environment than do developing nations
- B. many fertilizers are organic substances that produce no ill effects in humans
- C. agricultural chemicals can be used on a small scale and still significantly improve crop yields
- D. the use of pesticides is unnecessary if high-yield crop varieties are adopted
Correct Answer & Rationale
Correct Answer: C
Option C aligns with the idea that improving crop yields can be achieved through targeted use of agricultural chemicals, suggesting a balanced approach rather than widespread reliance. This reflects the author's likely advocacy for sustainable practices that enhance productivity without overwhelming environmental concerns. Option A diverts the focus to industrialized nations, which may not directly address the statement's emphasis on developing nations' agricultural needs. Option B incorrectly implies that all fertilizers are harmless, overlooking potential environmental impacts. Option D dismisses the potential benefits of pesticides entirely, which may not align with the author's nuanced view on agricultural practices.

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.

The author implies that the social sciences:
- A. are valued for their techniques
- B. can make no contribution to progress
- C. cannot deal with long-term issues
- D. may someday add to the world's knowledge
Correct Answer & Rationale
Correct Answer: D
The social sciences are portrayed as fields that hold potential for future contributions to global knowledge, indicating optimism about their evolving role. Option A suggests that their value lies solely in techniques, which limits their broader impact. Option B dismisses their potential entirely, contradicting the author's implication of future contributions. Option C incorrectly asserts that social sciences cannot address long-term issues, overlooking their capability to analyze historical trends and societal changes. Thus, the emphasis on future contributions aligns best with the text's implications.

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.

The author's description focuses mainly on Coleman's:
- A. humility
- B. audacity
- C. creativity
- D. generosity
Correct Answer & Rationale
Correct Answer: B
The author's description emphasizes Coleman's audacity, showcasing his boldness and willingness to take risks in pursuit of his goals. This trait is pivotal in illustrating his character and driving force. Option A, humility, is not a central theme; instead, Coleman's confidence is highlighted. Option C, creativity, while relevant, is secondary to his audacious nature, which propels his innovative ideas. Option D, generosity, does not align with the primary focus, as the text centers on his daring actions rather than acts of giving. Thus, audacity stands out as the defining characteristic.
