HESI A2 Grammar Practice Exam

Correct Answer: D

Rationale: The correct answer is D: his. In this sentence, "Mr. Menotti's wife" indicates possession, meaning the belongings belong to Mr. Menotti. Therefore, the possessive pronoun "his" is the most appropriate choice to replace the underlined words. Choosing A (her) would imply the belongings belong to the wife, not Mr. Menotti. Using B (him) would suggest that the wife collected Mr. Menotti himself, not his belongings. Option C (he) is a subject pronoun and does not indicate possession, so it is not suitable in this context.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma. A comma is used to separate two independent clauses when they are joined by a coordinating conjunction (such as "and" in this case). In the given sentence, "In addition to the hospital's regularly scheduled festivities" and "the custodians celebrate with a party of their own" are two independent clauses joined by "In addition to." Therefore, a comma is needed before the coordinating conjunction "In addition to" to make the sentence grammatically correct. Choice A (Period) is incorrect because a period would create two separate sentences, which is not the intended structure. Choice C (Apostrophe) is incorrect as there is no possessive form being used in the sentence. Choice D (Semicolon) is incorrect as a semicolon is not necessary to join these two independent clauses when a coordinating conjunction is present.

Correct Answer: B

Rationale: The correct answer is B: has. In this sentence, "One of the students" is a singular subject, so the correct verb form should be singular as well. "Has" is the correct singular form of the verb to agree with the singular subject. Choice A (have) is incorrect as it is a plural form. Choice C (are) is incorrect as it is also a plural form. Choice D (is) is incorrect as it is not the correct verb form to match the subject "students."

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."

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.
