HESI A2 Vocabulary Quizlet

Correct Answer: A

Rationale: The correct answer is A: "Is." In the sentence, "Economics" is a singular subject, so it should be followed by the singular verb "is." "Been" (B) is past tense and doesn't match the present tense in the sentence. "Am" (C) is first-person singular, not third-person singular like the subject "Economics." "Are" (D) is plural, which doesn't agree with the singular subject. Therefore, "is" is the correct verb choice to maintain subject-verb agreement.

Correct Answer: D

Rationale: The correct answer is D: forbid. 'Proscribe' means to officially forbid something. The root word 'pro' means 'before' or 'in front of,' and 'scribe' means 'write.' Therefore, 'proscribe' literally means 'to write before,' as in writing a law or rule to prohibit something. Choice A, anticipate, is incorrect as it means to expect or foresee. Choice B, prevent, is incorrect as it means to stop something from happening. Choice C, defeat, is incorrect as it means to overcome or win against someone or something.

Correct Answer: A

Rationale: The correct answer is A: Be observed. In the sentence, "be observed" is not correctly used because the verb "observe" should be in the passive form "observed" to match the tense of the sentence. The correct form should be "Confidentiality should be observed at all times." The other choices (B, C, D) are all used appropriately in the sentence and do not have any grammatical errors.

Correct Answer: C

Rationale: The correct answer is C: Hers. In the sentence, "hers" is used as a possessive pronoun, indicating ownership. However, in this context, it should be "her" instead of "hers" since "her" is the possessive form of the pronoun. Therefore, "hers" is grammatically incorrect in this sentence. The other choices, A, B, and D, are all correct in the sentence and do not contain any grammatical errors.

Correct Answer: D

Rationale: The correct answer is "D: Having." In this sentence, the verb form needs to be in the present participle form to show an ongoing action. "Having" is the present participle of the verb "have," which is used to indicate an action in progress. The other choices, A: Going, B: Go, and C: Have, do not fit the context of the sentence as they do not convey the continuous nature of the action required in this sentence. "Going" is a gerund, "Go" is the base form, and "Have" is the infinitive form, none of which are suitable for expressing ongoing action in this context.
