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: B

Rationale: The correct contraction for "They are" is B: They're. The contraction "They're" combines the pronoun "They" and the verb "are" into one word. "Their" (A) is a possessive pronoun, not a contraction. "The're" (C) is not a valid contraction in English. Option D, "No contraction used," is incorrect as there is a contraction for "They are," which is "They're."

Correct Answer: A

Rationale: The correct answer is A: stealthy. 'Insidious' means proceeding in a gradual, subtle way but with harmful effects. This aligns with the definition of stealthy. The word 'deadly' (B) is close but doesn't capture the gradual aspect. 'Collapsed' (C) and 'new' (D) are completely unrelated and do not fit the definition of 'insidious.'

Correct Answer: A

Rationale: The correct answer is A: Were. In this sentence, the verb should be in the subjunctive mood to express a hypothetical situation. "Were" is the correct subjunctive form for the verb "to be" in the past tense when used in this context. It indicates an unreal or hypothetical situation. The other choices, B: Is, C: Be, and D: Was, are incorrect because they do not correctly represent the subjunctive mood required for hypothetical or unreal situations. "Is" is present tense, "Be" is an infinitive form, and "Was" is past tense but not the correct subjunctive form in this context.

Correct Answer: B

Rationale: The correct answer is B: patent. The word 'patent' means open or accessible to all. It is the most appropriate synonym for 'open' among the choices. 'Inverted' (A) means turned upside down, not open. 'Convent' (C) refers to a religious community, not open. 'Converted' (D) means changed or transformed, not open. Therefore, 'patent' is the correct choice based on the definition and context provided.
