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.
Which of the following results is LEAST compatible with the goal expressed in the third sentence of Passage 2 ('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')?
- A. An international ban on the use of agrochemicals drives several multinational corporations out of business
- B. A species of bird becomes extinct after forests in which these birds nested are cleared to create farmland
- C. A rural community shows an increased rate of disease after local farmers adopt chemical-intensive techniques
- D. Government subsidies to farmers encourage overproduction of certain crops to the detriment of others
Correct Answer & Rationale
Correct Answer: C
Option C is least compatible with the goal of increasing crop yields while protecting human health and the environment. An increase in disease rates due to chemical-intensive farming directly contradicts the aim of safeguarding human health. Option A, while it may harm businesses, reflects a move towards environmentally sensitive practices by banning harmful chemicals. Option B highlights the negative ecological impact of deforestation for agriculture, which undermines environmental health. Option D addresses overproduction and its ecological consequences, aligning with the need for sustainable practices. Thus, C is the option that most clearly opposes the stated goal.

What assumption does the author of the passage make?
- A. Gases produced by algae will be cheaper to produce than other gases.
- B. The Department of Energy is already using hydrogen-producing algae as a source of energy.
- C. Mutant versions of algae will not be capable of the process of photosynthesis.
- D. Readers do not associate the Department of Energy with algae research.
Correct Answer & Rationale
Correct Answer: D
The assumption that readers do not associate the Department of Energy with algae research is supported by the passage's context, which aims to highlight the potential of algae in energy production. This suggests a need to clarify the Department's involvement. Option A is incorrect as the passage does not provide a comparison of costs related to gas production. Option B is misleading; the passage does not confirm the Department's current use of hydrogen-producing algae. Option C is not supported; the passage does not address the capabilities of mutant algae in photosynthesis. Thus, option D aligns with the author's intent to bridge a knowledge gap.

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.

The narrator primarily portrays the woman she is observing as someone who is:
- A. modest and self-effacing
- B. imposing and dignified
- C. youthful and energetic
- D. angry and impatient
Correct Answer & Rationale
Correct Answer: B
The portrayal of the woman emphasizes her imposing and dignified presence, suggesting strength and confidence. This is evident through her posture and the way she commands attention in her environment. Option A, modest and self-effacing, contradicts the strong impression she leaves, as she does not appear to shy away from the spotlight. Option C, youthful and energetic, overlooks the woman's gravitas and maturity, focusing instead on a fleeting quality. Option D, angry and impatient, misrepresents her demeanor, which is more composed and authoritative than reactive. Thus, the emphasis on dignity and presence aligns best with the narrator's observations.

Which word best completes the sentence?
- A. malleable
- B. obscure
- C. ominous
- D. vigorous
Correct Answer & Rationale
Correct Answer: A
In this context, "malleable" refers to something that can be easily shaped or influenced, making it the most fitting choice for a sentence discussing adaptability or flexibility. Option B, "obscure," implies something that is not well-known or hard to understand, which does not align with the intended meaning. Option C, "ominous," suggests a sense of foreboding or threat, which is unrelated to the idea of adaptability. Option D, "vigorous," conveys strength or energy but lacks the nuance of flexibility that "malleable" provides. Thus, "malleable" is the most appropriate word to complete the sentence.
