HESI A2 Vocabulary Practice Test

Correct Answer: B

Rationale: The correct answer is B. "became" is the correct verb form to use in this sentence because it is in the past tense and matches the timing of the action described. "Become" (choice A) is in the present tense and does not fit the past context of the sentence. "Been" (choice C) is a past participle form and does not work as the main verb in this sentence. "Had become" (choice D) is in the past perfect tense and is not necessary in this sentence as the simple past tense "became" is sufficient to convey the meaning.

Correct Answer: D

Rationale: The correct answer is D because in this sentence, 'fast' is modifying the verb 'runs,' making it an adverb. Adverbs modify verbs, adjectives, or other adverbs, indicating how an action is performed. In choices A and B, 'fast' is used as an adjective to describe the car, not modifying a verb. In choice C, 'fast' is an adjective describing the runner, not modifying a verb.

Correct Answer: B

Rationale: Step-by-step rationale: 1. "Precipitous" is often used to describe something happening quickly or suddenly. 2. The word "swift" means happening with speed and quickness. 3. Therefore, "swift" best aligns with the definition of "precipitous." Summary: - Choice A (Slow): Incorrect, as "slow" is the opposite of what "precipitous" typically means. - Choice C (Gradual): Incorrect, as "gradual" means happening slowly over time, opposite of "precipitous." - Choice D (Delayed): Incorrect, as "delayed" refers to something happening later than expected, not the suddenness of "precipitous."

Correct Answer: B

Rationale: The correct answer is B: Made worse. Exacerbated means to make a symptom or situation more severe or intense. Therefore, if a symptom is exacerbated, it is made worse. Choice A: Improving, is the opposite meaning. Choice C: Stayed the same, contradicts the definition of exacerbated. Choice D: Ameliorated means to improve or make better, which is the opposite of exacerbated.

Correct Answer: B

Rationale: The correct answer is B: Able to be heard. Audible refers to something that can be heard. This is because the term "audible" is derived from the Latin word "audire," which means "to hear." Therefore, when something is audible, it means it can be perceived by the sense of hearing. Incorrect choices: A: Impossible to hear - This is incorrect as audible means the opposite, something that can be heard. C: Visible - This is incorrect as audible pertains to sound, not sight. D: Silent - This is incorrect as audible refers to something that can be heard, not something that is silent.
