Grammar for HESI A2

Correct Answer: B

Rationale: The correct answer is B: their. In this sentence, "patients" is a plural noun, so the possessive pronoun "their" is the most appropriate to indicate that the coats belong to more than one patient. Choice A (his) is singular and would not match the plural noun "patients." Choice C (them) is an object pronoun, not a possessive pronoun. Choice D (theirs) is a possessive pronoun but is used as a subject pronoun, which does not fit the sentence structure. Therefore, choice B is the best substitution in this context.

Correct Answer: A

Rationale: The correct answer is A: its. In this sentence, "flock" is a singular noun, so the pronoun that refers back to it should also be singular. "Its" is the possessive form for singular nouns, while "their" (B) is plural. "It's" (C) is a contraction for "it is" and doesn't show possession. "They're" (D) is a contraction for "they are" and is also incorrect as it refers to a plural subject. Therefore, A is the only choice that correctly matches the singular subject "flock."

Correct Answer: B

Rationale: The correct answer is B: itself. In the sentence, "it" refers to the centrifuge, which is a singular neuter noun. Therefore, the pronoun to be used should also be singular and neuter, which is "itself." A: oneself is incorrect because "oneself" is used for reflexive pronouns referring to a person, not an inanimate object like a centrifuge. C: herself is incorrect because "herself" is used for feminine singular pronouns, which does not match the neuter "it" in the sentence. D: themselves is incorrect because "themselves" is a plural pronoun and does not agree with the singular noun "centrifuge."

Correct Answer: C

Rationale: The correct answer is C: deserve. In the sentence, "deserve" is used incorrectly as it implies that only a few students are worthy of their degrees, which is subjective and judgmental. The word should be replaced with "earn" to convey the intended meaning that only a few students have met the requirements to receive their degrees. A: pass - Used correctly to indicate movement through the doors. B: through - Used correctly as a preposition indicating the path of movement. D: degree - Used correctly to refer to the qualification obtained by the students.

Correct Answer: B

Rationale: The correct answer is B: to learn. In this case, the sentence requires the infinitive form "to learn" to show the purpose or intent of the surprise, indicating that the speaker was surprised in anticipation of learning about her dismissal. The other choices are incorrect because: A: learning - This is a gerund form, which does not align with the structure needed in this sentence. C: of learning - This construction is awkward and does not fit the context of the sentence. D: have learned - This implies past action, which is not the intended meaning in this sentence.
