Grammar for HESI A2

Correct Answer: A

Rationale: The correct answer is A: "of workers." This phrase is misplaced because it should directly follow "noticed" to maintain proper sentence structure. The phrase "a number of workers" should be placed immediately after "noticed" to clearly indicate what was noticed. The other choices (B, C, D) are not misplaced as they are correctly positioned within the sentence and do not disrupt the flow or meaning.

Correct Answer: B

Rationale: The correct answer is B: envelope. In the sentence, the word "envelope" is used incorrectly as it does not fit the context of the sentence. The sentence is asking for a folder to be given to the person who replies to the page, not an envelope. The other choices (A, C, D) are used correctly in the sentence and are essential to convey the intended meaning. "Give" is the verb indicating the action, "whoever" is the pronoun referring to an unspecified person, and "replies" is the verb indicating the action that the person needs to do to receive the folder.

Correct Answer: C

Rationale: The correct answer is C: "will be delighted." The sentence is in future tense, so the verb "to be" should also be in the future tense to maintain grammatical consistency. "Will be delighted" indicates a future event (graduating early) that will lead to the parents being delighted. The other choices are incorrect because they do not align with the future tense context of the sentence. A: "are delighted" is present tense, B: "were delighted" is past tense, and D: "will have been delighted" is unnecessarily complex and does not fit the sentence structure.

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: A

Rationale: The correct answer is A: lose. In the sentence, "Try not to lose patience or suffer a drop in morale," the word "lose" is used incorrectly because you don't "lose" patience; you "run out of" or "lack" patience. The word "lose" implies misplacing something physical, not an abstract concept like patience. The other choices (B: patience, C: suffer, D: morale) are used correctly in the sentence as they convey the intended meaning without any grammatical errors.
