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.

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.

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.

Although she had not grown up playing soccer, Jeanette was such an outstanding athlete, she scored more goals than any other member of the soccer team.
- A. athlete, she
- B. athlete, she had
- C. athlete that
- D. athlete that she
Correct Answer & Rationale
Correct Answer: D
Option D, "athlete that she," effectively introduces a defining clause that clarifies Jeanette's exceptional abilities. The word "that" connects her status as an athlete to her achievement, emphasizing the cause-and-effect relationship. Option A, "athlete, she," lacks a connector, making the sentence feel abrupt and incomplete. Option B, "athlete, she had," introduces unnecessary past tense that does not align with the context of her current achievements. Option C, "athlete that," is missing a crucial pronoun, making it grammatically incorrect. Thus, D provides the most coherent and grammatically sound structure.

Despite the difficulties he had encountered, the mountain climber had no fear when it ________ to high mountains.
- A. comes
- B. came
- C. has come
- D. had come
Correct Answer & Rationale
Correct Answer: B
Option B, "came," is appropriate here as it uses the simple past tense, which aligns with the context of the sentence about the climber's past experiences with high mountains. This tense indicates a completed action in the past, fitting well with "despite the difficulties he had encountered." Option A, "comes," is incorrect because it uses the simple present tense, which does not match the past context of the sentence. Option C, "has come," is also unsuitable since it implies a connection to the present, which does not align with the past experiences being discussed. Option D, "had come," suggests a past perfect tense that is unnecessary in this context, as the simple past suffices to convey the intended meaning.
