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.

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.

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.

In the second sentence of the passage ('a giant Saturn moon rocket dismantled into pieces for tourists to inspect, like lengths of fossilized bone from a mythic biotech dragon'), the simile primarily emphasizes the rocket's:
- A. dominance
- B. obsolescence
- C. superior engineering
- D. appeal to newcomers
Correct Answer & Rationale
Correct Answer: B
The simile compares the dismantled rocket to "fossilized bone from a mythic biotech dragon," highlighting its obsolescence. This imagery suggests that the rocket, once a marvel of technology, now resembles relics of a bygone era, evoking a sense of nostalgia rather than functionality. Option A, dominance, does not apply here, as the imagery does not convey power or superiority. Option C, superior engineering, is contradicted by the notion of the rocket being dismantled and inspected, which implies it is no longer operational. Option D, appeal to newcomers, is less relevant; the focus is more on the rocket's past significance than its current allure.

Both authors indicate that meeting the world's food needs should not come at the expense of:
- A. innovative farming practices
- B. environmental integrity
- C. humane treatment of animals
- D. economic development
Correct Answer & Rationale
Correct Answer: B
Meeting the world’s food needs should prioritize environmental integrity, as it ensures sustainable practices that protect ecosystems for future generations. If environmental health is compromised, long-term agricultural productivity is at risk. Option A, innovative farming practices, while important, can still be pursued without sacrificing environmental integrity. Option C, humane treatment of animals, is critical but may not directly relate to the broader environmental concerns outlined by the authors. Option D, economic development, is essential for food security, but it should not overshadow the imperative of maintaining ecological balance.
