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.

What does the passage suggest about the light bulbs used in the first train signaling systems?
- A. They were very fragile.
- B. They were all the same color.
- C. They were only illuminated at night.
- D. They were also used to signal automobile drivers.
Correct Answer & Rationale
Correct Answer: B
The passage indicates that the light bulbs in the first train signaling systems were designed to emit a specific color to convey signals, suggesting uniformity in color for clarity and safety. Option A is incorrect as the passage does not mention the fragility of the bulbs. Option C is misleading; while the bulbs may have been primarily used at night, the passage does not explicitly state that they were only illuminated then. Option D is also incorrect; the passage focuses on train signaling without reference to their use for automobile drivers. Thus, the emphasis on color highlights the importance of consistent signaling in train operations.

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.

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.

The passage is mainly discussing the Mississippi River's
- A. depth
- B. length
- C. width
- D. location
Correct Answer & Rationale
Correct Answer: C
The passage primarily focuses on the Mississippi River's width, detailing its varying measurements at different points along its course. This emphasis on width is crucial for understanding the river's impact on surrounding ecosystems and human activities. Option A, depth, is mentioned but not the main focus, making it less relevant. Option B, length, while significant, does not capture the central theme of the passage. Option D, location, is addressed but serves more as context rather than the primary discussion point. Therefore, width is the key aspect highlighted throughout the text.
