Passage
Have you ever wondered why everything you eat or drink right after brushing your teeth tastes bad? The cause is sodium laureth sulfate, an ingredient commonly added to toothpaste to make the paste foamy. Unfortunately, sodium laureth sulfate inhibits the taste buds that perceive sweetness, while removing molecules that keep bitter tastes from overwhelming our tongues. As a result, sweet flavors are reduced while bitter flavors are enhanced.
The word "perceive" in sentence 3 of the passage most nearly means
- A. feel
- B. generate
- C. predict
- D. sense
Correct Answer & Rationale
Correct Answer: D
The word "perceive" in this context closely aligns with "sense," as it refers to the ability to become aware of something through one’s senses or intuition. Option A, "feel," suggests a more emotional or physical response, which does not fully capture the broader cognitive aspect of perception. Option B, "generate," implies creating something, which deviates from the idea of recognizing or understanding. Option C, "predict," relates to forecasting future events, rather than simply recognizing or interpreting current stimuli. Thus, "sense" best encapsulates the meaning of "perceive" in this instance.

- A. The achievement of Richard Pearse
- B. The problems of early airplanes
- C. The first flight in the United States
- D. The history of long-distance flight
Correct Answer & Rationale
Correct Answer: A
The passage primarily discusses the achievement of Richard Pearse, highlighting his significant contributions to aviation. His pioneering efforts are central to the narrative, showcasing his innovations and milestones. Option B focuses on the problems of early airplanes, which, while relevant, does not capture the primary focus on Pearse's accomplishments. Option C mentions the first flight in the United States, a separate historical event that is not the main topic of the passage. Option D addresses the broader history of long-distance flight, which encompasses many figures and events, but does not specifically center on Pearse's individual achievements.

The following sentence would best fit immediately after which sentence in the second paragraph (sentences 3-6)? Meanwhile, the robots' eye and body movements mimic those of the human visitors they represent.
- A. Sentence 3
- B. Sentence 4
- C. Sentence 5
- D. Sentence 6
Correct Answer & Rationale
Correct Answer: C
The sentence about the robots’ eye and body movements aligns best with Sentence 5, which likely discusses how these movements enhance the interaction between robots and human visitors. This connection emphasizes the purpose of mimicking human behavior. Sentence 3 may introduce the robots but does not specifically relate to their movements. Sentence 4 might focus on a different aspect of the robots, such as their design or functionality, which doesn’t directly connect to the mimicry. Sentence 6 may conclude the paragraph, making it less suitable for introducing a detailed observation about movements. Thus, Sentence 5 provides the most relevant context for the new information.

The passage indicates that John Neville was
- A. the creator of the whiskey tax
- B. working for the government
- C. pardoned by the government
- D. a friend of George Washington's
Correct Answer & Rationale
Correct Answer: B
John Neville was indeed working for the government, specifically as a tax collector during the Whiskey Rebellion, which highlights his role in enforcing federal tax laws. Option A is incorrect; he did not create the whiskey tax but was involved in its implementation. Option C is misleading, as there is no indication in the passage that he was pardoned by the government. Option D is also wrong; while Neville may have had connections, the passage does not confirm him as a friend of George Washington. Thus, his official capacity as a government worker is the most accurate representation of his role.

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 suggests a gap in public awareness that the author aims to address. This perspective is crucial for framing the significance of the research discussed. Option A is incorrect as it makes a specific economic claim not supported by the passage. Option B incorrectly assumes the Department of Energy is currently using hydrogen-producing algae, which is not established in the text. Option C presumes that mutant algae cannot photosynthesize, but the passage does not provide evidence or context to support this claim. Thus, D accurately reflects the author's underlying assumption about public perception.
