Correct Answer: A

Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.

Correct Answer: A

Rationale: The correct answer is A: 'Makes a suggestion about.' The phrase 'suggests that' indicates that the study is proposing or indicating the possibility that vaping may have certain effects on cigarette smoking. It is not stating a fact or providing evidence, but rather making a suggestion or recommendation about the relationship between vaping and cigarette smoking. Choices B, C, and D are incorrect because the phrase 'suggests that' does not provide evidence, hint at an idea, or promote a plan, but rather presents a suggestion or possibility.

Correct Answer: A

Rationale: A compendium is a collection of concise but comprehensive information on a particular subject. Therefore, another word for compendium is "collection." The term "aptitude" refers to a natural ability to do something, not synonymous with compendium. "Conclusion" is a decision or judgment reached after considering the facts, not related to a compendium. "Humor" refers to the quality of being amusing or comic, not a synonym for compendium.

Correct Answer: D

Rationale: In this sentence, the word 'trepidation' is used to describe the feeling the students had when approaching the cadaver. Trepidation means a feeling of fear or anxiety about something that may happen, so it aligns most closely with the meaning of 'apprehension.' The students were hesitant or worried about facing the cadaver. Choice A ('Wonder') is incorrect as trepidation does not signify a feeling of wonder. Choice B ('Confusion') is incorrect as trepidation is not about being confused. Choice C ('Eagerness') is incorrect as trepidation is the opposite of eagerness; it indicates hesitation or anxiety, not excitement or enthusiasm.

Correct Answer: B

Rationale: In this context, the word 'winnowed' means to separate or eliminate less desirable individuals from a larger group, indicating that the applicants were being sifted out or singled out in this process. Therefore, the most appropriate meaning among the choices provided is 'separated.' 'Escorted' (Choice A) implies being accompanied or guided, which is not the intended meaning. 'Elevated' (Choice C) means raised or lifted, which does not fit the context. 'Summoned' (Choice D) suggests being called or requested to attend, which is also not the correct meaning in this context.
