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.

Why does the author mention that only men signed the Mayflower Compact?
- A. To show the similarities between the Compact and the Constitution
- B. To suggest that the Compact was not a perfect model of government
- C. To indicate that men were better lawmakers than women
- D. To imply that only men were on board the Mayflower
Correct Answer & Rationale
Correct Answer: B
The mention of only men signing the Mayflower Compact highlights the limitations of this early governance document, suggesting it was not a perfect model of government. It reflects the societal norms of the time, where women's voices were excluded from formal political processes, indicating a lack of representation. Option A incorrectly suggests a direct comparison with the Constitution, which is not the focus. Option C perpetuates a gender bias that is not supported by the text. Option D misinterprets the context; while only men signed, it does not imply that only men were aboard the Mayflower, as historical records show women were present as well.

According to scientists, the seven separate continents of the world, in the far distant past, one vast land mass.
- A. the world, in the far distant past
- B. the world, being in the far distant past
- C. the world were, in the far distant past
- D. the world was, in the far distant past
Correct Answer & Rationale
Correct Answer: D
Option D accurately uses the verb "was," which agrees with the singular subject "the world." This structure clearly conveys that, historically, the continents formed one vast land mass. Option A lacks a verb, making it an incomplete thought. Option B incorrectly uses "being," which is not suitable in this context and disrupts the sentence's clarity. Option C uses "were," which does not agree with the singular subject and creates confusion about the subject-verb relationship. Thus, D is the only option that maintains grammatical correctness and clarity.

We can infer that the reason the glass tubes were bent was that
- A. the Paris Exposition display was considered unsatisfactory
- B. straight tubes are not as bright as bent ones
- C. it is difficult to form letters with straight tubes
- D. neon gas burns out quickly in straight tubes
Correct Answer & Rationale
Correct Answer: C
The bending of glass tubes is primarily linked to the ability to form letters and shapes, making option C the most logical choice. Bent tubes allow for the creation of recognizable letters, essential for signage. Option A suggests the display's quality influenced the design, but it lacks direct relevance to the functionality of the tubes. Option B implies that brightness is affected by the shape of the tubes, which is misleading; brightness is more about gas type and tube diameter than shape. Option D inaccurately claims that neon gas burns out quickly in straight tubes; gas longevity is not dependent on tube shape but rather on electrical conditions and gas quality.

Which is the best version of the underlined portion of sentence 3 (reproduced below)? High-tech teams around the world are working on projects designed to enhance people's telepresence "their sense of physically being in a location even when they are actually thousands of miles away.
- A. (as it is now)
- B. telepresence', their
- C. telepresence.' Their
- D. telepresence' their
Correct Answer & Rationale
Correct Answer: A
Option A maintains the original structure and punctuation, effectively conveying the intended meaning without introducing errors. The phrase "telepresence" is correctly followed by a quotation mark, and the sentence flows logically. Option B incorrectly uses a comma instead of a period after "telepresence," which disrupts the sentence's clarity and structure. Option C improperly replaces the comma with a period, creating a fragment because "Their sense..." would then be a standalone sentence without proper connection to the previous thought. Option D lacks the necessary punctuation to separate the two ideas, resulting in a confusing and grammatically incorrect construction.
