HESI A2 Grammar Practice Test 2024

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: A

Rationale: The correct answer is A: amount. In this sentence, the intern was surprised by the degree or intensity of pain he was in after his first day of work. "Amount" is the most appropriate word to convey the level of pain experienced. B: frequency does not fit the context as it refers to how often something occurs, not the intensity. C: number is not suitable as it typically refers to quantities of things, not the intensity of pain. D: amplitude is more commonly used in the context of sound or waves, not in describing pain intensity.

Correct Answer: D

Rationale: The correct answer is D: Our. In the sentence, "Our screaming took the shopkeeper by surprise," the possessive pronoun "Our" correctly indicates that the screaming belongs to the group of people being referred to. "We," "They," and "Them" are subject pronouns, not possessive pronouns, and do not indicate ownership in the sentence. Therefore, they do not make the sentence grammatically correct. "Our" is the only choice that fits the context and makes the sentence grammatically correct.

Correct Answer: D

Rationale: The correct answer is D: Our. In the sentence, 'Screaming our took the shopkeeper by surprise,' the word 'our' functions as a possessive determiner, indicating that the screaming belonged to 'us.' The word 'our' correctly connects the subject 'us' to the action of screaming. Rationale: A: We - Incorrect. 'We' is a subject pronoun and cannot function as a possessive determiner in this context. B: They - Incorrect. 'They' is a subject pronoun and does not show possession. C: Them - Incorrect. 'Them' is an object pronoun and cannot indicate possession.
