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.

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.

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.

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.

In context, 'Telemundo' and 'Ms. magazine' serve as examples of media that:
- A. devised similar marketing techniques
- B. were created by the same media visionary
- C. underwent profound changes as a result of Johnson's work
- D. were designed to appeal to particular groups of consumers
Correct Answer & Rationale
Correct Answer: D
Both 'Telemundo' and 'Ms. magazine' were designed to cater to specific audiences, focusing on the needs and interests of their respective consumer groups. Telemundo targets the Hispanic community, providing culturally relevant content, while Ms. magazine addresses feminist issues and women’s rights. Option A is incorrect as there is no evidence that both utilized similar marketing techniques. Option B is misleading; they were not created by the same visionary. Option C is inaccurate; while Johnson's work influenced media, it did not specifically lead to profound changes in either outlet.
