During the process of photosynthesis, algae produce a small amount of hydrogen gas. Recently, microbiologists funded by the Department of Energy figured out how to create mutant versions of algae that generate much more hydrogen. You are probably wondering why the Department of Energy is funding this research. The answer is that the hydrogen produced by algae could one day be used to provide energy to entire cities
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 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 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 statements does the passage most directly counter?
- A. Having a non-arts job stifles and detracts from an artist's creative work
- B. For people working in non-arts professions, art is more than just an entertaining distraction
- C. The poetry of William Carlos Williams exemplifies autobiographical poetry
- D. Work and art cannot meaningfully complement each other
Correct Answer & Rationale
Correct Answer: D
Option D is effectively countered by the passage, which likely illustrates how work and art can coexist and enhance each other, suggesting that they can provide mutual inspiration and growth. Option A misrepresents the relationship between non-arts jobs and creativity, as the passage may argue that such jobs can actually foster artistic development rather than hinder it. Option B acknowledges the significance of art in non-arts professions, which aligns with the idea that art can coexist with other careers, rather than opposing them. Option C focuses on a specific aspect of poetry that is unrelated to the broader theme of work and art's relationship, making it less relevant to the passage's main argument.

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.
