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.

It can most reasonably be inferred from the passage that the music products industry would have a higher share of the e-commerce market if:
- A. entry-level school music instruments were sold to schools' music directors rather than directly to students
- B. the consumer market were to place less value on convenience and variety and more on competitive pricing
- C. a few types of music products sold predominantly in brick-and-mortar stores were excluded from the calculation
- D. brick-and-mortar store managers improved customer service and provided better training for their installation experts
Correct Answer & Rationale
Correct Answer: C
The inference about the music products industry’s higher e-commerce market share hinges on the exclusion of certain products sold mainly in physical stores. If these items are not considered, the e-commerce segment could appear more dominant. Option A suggests a shift in sales strategy, but it doesn’t directly impact the overall market share dynamics. Option B misplaces the focus on consumer preferences, which does not inherently increase e-commerce share. Option D addresses customer service improvements in physical stores, which would not enhance online sales. Thus, excluding certain products from the calculation is the most logical inference for a higher e-commerce share.

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.

The final paragraph suggests that seeing the woman has caused the narrator to:
- A. face the negative feelings she has about her new home
- B. realize that she misses her mother more than she admits
- C. think about her own feelings about her family and background
- D. remember the reason she moved away from her home country
Correct Answer & Rationale
Correct Answer: C
The final paragraph emphasizes the narrator's introspection triggered by seeing the woman, leading her to reflect on her own feelings about family and background. This deep connection to identity is central to her experience. Option A misinterprets the focus; while negative feelings may exist, the emphasis is on personal reflection rather than facing negativity. Option B suggests a specific emotion related to her mother, which is not explicitly indicated in the text. Option D implies a recollection of her reasons for moving, but the paragraph centers more on her current emotional state rather than past motivations.

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.
