HESI A2 Grammar Practice Exam

Correct Answer: A

Rationale: The correct answer is A: volunteered. In the sentence, "the first time she volunteered at the hospital," the verb should be in the past tense to match "the first time." "Volunteered" is the correct past tense form of the verb "volunteer" in this context. Choice B: volunteering is in the present participle form and does not fit the past tense requirement. Choice C: was volunteered is in the passive voice and does not make sense in the context of Cathy actively asking questions. Choice D: volunteer is in the base form and does not match the past tense needed in the sentence.

Correct Answer: B

Rationale: The correct answer is B: Comma. In the sentence "The days seem long, but the nights seem even longer," a comma is needed before the coordinating conjunction "but" to separate the two independent clauses. This comma helps clarify the relationship between the two contrasting ideas. Choices A, C, and D are incorrect because a period would create two short, choppy sentences, a colon is not needed for this context, and an apostrophe is used for possession or contractions, which are not relevant in this sentence.

Correct Answer: A

Rationale: The correct answer is A: principle. In the sentence, the word should be "principal" to refer to the main or leading role. "Principle" refers to a fundamental truth or belief. The other choices, B: role, C: provision, and D: convenient are all spelled correctly and fit appropriately in the sentence context.

Correct Answer: C

Rationale: The correct answer is C: them. In the sentence, "The children and them performed a skit for the elderly patients," the pronoun "them" is used to refer to a group of people (children and others). The pronoun "them" is the objective form of the pronoun "they" and is used to represent the object of the sentence. In this case, the children and other individuals are the ones performing the skit, making "them" the appropriate choice. Choice A: "he" is incorrect as it would refer to a singular male individual, not a group. Choice B: "me" is incorrect as it is the objective form of the pronoun "I" and does not fit the subject of the sentence. Choice D: "her" is incorrect as it is the objective form of the pronoun "she" and does not match the subject of the sentence.

Correct Answer: C

Rationale: Rationale: The correct answer is C because "promised to conduct" is the correct phrasing to convey the intended meaning of the sentence. The verb "promised" should be followed by the infinitive form "to conduct" to indicate the action the students committed to doing. Summary of other choices: A: "conduct" is incorrect as it does not follow the structure of the sentence. B: "conducting" is incorrect as it is a present participle and does not fit the context of the sentence. D: "to be conducted" is incorrect as it changes the meaning of the sentence, suggesting that the students would be the ones being conducted.
