HESI A2 Grammar Practice Exam

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: 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 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: C

Rationale: The correct answer is C: our. In the sentence, "The doctor and I went over the doctor's and my notes," the possessive pronoun "our" is the best substitute for "the doctor's and my." This is because "our" indicates joint ownership, which is appropriate in the context of both individuals sharing notes. The possessive pronouns "his" (A), "their" (B), and "mine" (D) do not accurately reflect the shared ownership implied in the sentence. "His" and "their" suggest singular and plural ownership, respectively, while "mine" implies sole possession by one person.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma (Choice B). The comma is used to separate the dependent clause "Because of a major accident on the freeway" from the independent clause "the emergency room was overcrowded." This creates a clear and correct sentence structure. A period (Choice A) would create two separate sentences, which is not necessary in this case. An exclamation point (Choice C) is inappropriate as the sentence is not expressing excitement or strong emotion. A semicolon (Choice D) is not suitable as the clauses are not closely related or part of a list.
