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.

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.

Our math teacher claimed that calculus, despite its complexities, were as easy as any other subject.
- A. were as
- B. was as
- C. is to be
- D. to be
Correct Answer & Rationale
Correct Answer: B
In this context, the subject "calculus" is singular, so it requires a singular verb form. "Was as" correctly matches the singular subject, indicating that calculus is being compared to other subjects in the past. Option A, "were as," incorrectly uses the plural verb "were," which does not agree with the singular noun "calculus." Option C, "is to be," implies a future action or state, which does not fit the intended meaning of comparing past experiences. Option D, "to be," lacks a verb and does not form a complete thought, making it grammatically incorrect.

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.

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 highlights its significance in navigation and ecology. Option A, depth, is not the main topic; while depth may be mentioned, it does not receive the same level of attention. Option B, length, is also a lesser focus, as the passage does not delve into the river's overall distance. Option D, location, is addressed but serves more as context rather than the central theme. Thus, width emerges as the key aspect discussed in the passage.
