HESI A2 Grammar Practice Exam

Correct Answer: C

Rationale: The correct answer is C: boys'. In this sentence, the possessive form of "boys" should be "boys's" to indicate that the pranks belonged to the four boys. The incorrect use of the apostrophe after "boys" in choice C makes it the misspelled word. "Everyone" (choice A), "fraternity" (choice B), and "sophomoric" (choice D) are spelled correctly in the context of the sentence.

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: 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: C

Rationale: The correct answer is C: "had rarely". This is incorrect as it should be "rarely had" to follow correct word order for adverbs of frequency. "Had rarely" is an incorrect placement of the adverb in the sentence structure. "Before their" (A) is correct as it introduces a time frame. "Children had" (B) is also correct as it identifies the subject and tense. "Rarely eat" (D) is incorrect as it changes the tense and does not match the past perfect tense used in the sentence.

Correct Answer: D

Rationale: The correct answer is D, "inputting." In the sentence, "inputting" is the gerund form of the verb "input," which correctly conveys the ongoing action of Kalinda spending part of her day working with data from the lab. The verb form "inputting" is needed to maintain parallel structure in the sentence. Choice A, "inputs," is incorrect because it is the present tense form of the verb and does not match the sentence structure. Choice B, "input," is incorrect as it is a singular noun and does not convey the continuous action. Choice C, "having input," is incorrect because it introduces unnecessary complexity with the auxiliary verb "having."
