HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A because "the thief" indicates a singular person, so the pronoun "he" should be used. The subject-verb agreement is crucial in this sentence. Choice B uses "he" correctly but includes a different verb. Choices C and D use the incorrect pronoun "they," which does not agree with "the thief." Additionally, "hid" in choice C is not the appropriate action after robbing a bank, and "fled" in choice D is plural and doesn't match with "the thief." Therefore, option A is the correct choice based on subject-verb agreement and logical consistency.

Correct Answer: A

Rationale: The correct answer is A: Prefix. A prefix is a word part placed before a word to change its meaning. It modifies the root word's meaning. For example, adding "un-" before "happy" changes the meaning to "unhappy." Affix (B) is a broader term that includes both prefixes and suffixes. Suffix (C) is a word part placed after a word, and Vocab (D) stands for vocabulary, which is not directly related to changing the meaning of a word.

Correct Answer: B

Rationale: The correct answer is B: Confinement away from the general population. Quarantine refers to the isolation of individuals who may have been exposed to a contagious disease to prevent the spread to others. This choice is correct because quarantine involves separating potentially infected individuals from the rest of the population. Choice A (Isolation) is similar but not specific to disease control measures. Choice C (Treatment) does not capture the concept of separation. Choice D (Exposure) is incorrect as quarantine is about preventing exposure, not promoting it.

Correct Answer: A

Rationale: The correct answer is A: hung up. In this context, "hung up" means to end a phone call abruptly. The phrase "hung up on him" indicates that she ended the call without listening or responding to him. Choices B, C, and D do not fit the context. "Picked" and "held" do not convey the action of ending a call, while "held on" means to stay connected on the call, which contradicts the situation where she was mad at him. Therefore, A is the most appropriate choice.

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.
