HESI A2 Grammar Practice Exam

Correct Answer: B

Rationale: The correct answer is B: subscribes. In the sentence, "One out of four doctors" is the subject, which is singular. Therefore, the verb should also be singular to match, making "subscribes" the correct form. Choice A, subscribe, is incorrect because it is the plural form. Choice C, subscribing, is incorrect as it is a present participle and does not match the subject. Choice D, are subscribed, is incorrect as it is in the plural form and passive voice, which does not fit the sentence structure.

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.

Correct Answer: B

Rationale: The correct answer is B: lead. In the sentence, the correct past tense form of "lead" should be "led" as it is referring to a past action. "Lead" is the present tense form, while "led" is the past tense form. A: attending, C: entourage, and D: interns are all spelled correctly and are appropriate in the context of the sentence.

Correct Answer: D

Rationale: The correct answer is D, "in the auditorium." This phrase is misplaced because it should come immediately after "presentation" for clarity. The sentence should read, "At a presentation in the auditorium, he informed us about the dangers of drugs and alcohol." The other choices are not misplaced as they are all positioned correctly in the sentence and contribute to the overall meaning.

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."
