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 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.

Why does the author place quotation marks around the word 'patriotic' (sentence 2)?
- A. To attribute to postwar Americans the perception of Wrigley’s gum as patriotic
- B. To praise the patriotism the Wrigley Company demonstrated during wartime
- C. To show that American soldiers used the word 'patriotic' to describe Wrigley’s gum
- D. To reveal that the Wrigley Company changed the name of its gum to include the word 'patriotic'
Correct Answer & Rationale
Correct Answer: A
The use of quotation marks around 'patriotic' indicates that the term reflects the perception held by postwar Americans rather than the author's own endorsement. This suggests a distance from the term, highlighting it as a viewpoint rather than an absolute truth. Option B misinterprets the author's intent; the quotation marks do not imply praise for the Wrigley Company's actions. Option C inaccurately suggests that soldiers specifically coined the term in reference to the gum, which is not supported by the context. Option D incorrectly assumes that the company changed the product name, which is not indicated in the text.

Which choice best describes the overall structure of the passage?
- A. The passage examines the effect of decreased environmental awareness on some animals' predation risk and then describes the strategies those animals use to increase their environmental awareness while sleeping.
- B. The passage distinguishes between bihemispheric slow-wave sleep (BSWS) and unihemispheric slow-wave sleep (USWS) and then explains why USWS is less beneficial than BSWS for animals such as mallards and penguins.
- C. The passage discusses the advantages for some animals of sleeping at the center of a group and then questions whether those advantages extend to colonial birds.
- D. The passage provides an extended description of how mallards typically sleep and then compares sleeping behaviors in mallards to those in penguins.
Correct Answer & Rationale
Correct Answer: C
Choice C accurately captures the passage's structure, which begins by exploring the benefits of group sleeping for certain animals and then raises a critical inquiry regarding the applicability of these benefits to colonial birds. This dual focus on advantages and questioning reflects a balanced examination of the topic. Option A misrepresents the content by suggesting a focus on predation risk and strategies for environmental awareness, which is not the main theme. Option B incorrectly centers on a comparison of sleep types, neglecting the broader discussion of group sleeping benefits. Option D inaccurately emphasizes a detailed comparison of mallards and penguins, rather than the initial exploration of group sleeping advantages.

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.
