HESI A2 Grammar Practice Test 2024

Correct Answer: D

Rationale: The correct answer is D, "laying." The verb "laying" is incorrect because it should be "laying bricks" instead of "laying a brick." The correct form should be "laying bricks to build a foundation." The other choices (A, B, C) are not incorrect in the sentence and do not affect the sentence's overall meaning or grammar.

Correct Answer: A

Rationale: The correct answer is A: who. In the sentence, "Children who obey their parents tend to do better in school," the word "who" is a relative pronoun that introduces a clause describing the children who obey their parents. The relative pronoun "who" is used to refer to people. It connects the main clause to the subordinate clause in a grammatically correct way. Explanation for why other choices are incorrect: B: which - "Which" is used for things or animals, not people. C: should - "Should" is a modal verb indicating obligation or possibility, but it does not fit grammatically in this context. D: to - "To" is a preposition and does not serve the same function as a relative pronoun in connecting the clauses.

Correct Answer: D

Rationale: The subject of a sentence is the noun or pronoun that performs the action in the sentence. In this case, "The nurses" is the subject because they are the ones performing the action of going to the conference room. "D: nurses" is the correct answer. A: conference - This is the object of the preposition "to" and not the subject. B: went to - This is the action verb phrase and not the subject. C: room - This is the object of the preposition "to" and not the subject.

Correct Answer: A

Rationale: The correct answer is A because it correctly uses the participial phrase "Walking home from class" to modify the subject "the students." This structure indicates that the students were walking home while watching the snow begin to fall. The other choices incorrectly use different verb forms or do not effectively connect the action of walking home with the snow falling. Choice B incorrectly suggests that the snow is actively falling on the students while they are walking home. Choice C lacks a clear connection between the students walking home and the snow falling. Choice D does not effectively link the action of the students watching the snow fall with them walking home.

Correct Answer: D

Rationale: The correct answer is D: have to. In the sentence, the verb "try" should be followed by a base form of the verb, which is "have to" in this case. "Have to" indicates the necessity or obligation to try hard. A: "has to" is incorrect because it is present tense and does not match the tense of the sentence. B: "haven't" is incorrect because it does not fit the structure of the sentence. C: "had to" is incorrect as it indicates a past obligation, which is not suitable in this context. Therefore, D is the correct choice as it maintains the correct tense and meaning of the sentence.
