HESI A2 Grammar Practice Test

Correct Answer: B

Rationale: The correct answer is B: stationary. In this context, stationary should be spelled as stationery, which refers to paper, envelopes, and other writing materials. The word stationary means not moving, which does not fit the context of chairs and interns being agitated. Their, seated, and agitated are spelled correctly and are appropriate in the context of the sentence.

Correct Answer: B

Rationale: The correct answer is B because it clearly states the age at which the event occurred ("When I was seven"). This provides a clear timeline and clarity of the subject and action. A: Ambiguous due to placement of "at the age of seven" C: Incorrect subject-verb relationship and illogical action D: Incorrect placement of the age reference and confusing subject-verb relationship.

Correct Answer: C

Rationale: The correct answer is C: study. In the sentence, "study" should be "studies" to match the singular subject Sidney. The verb should agree with the subject in number, so it should be "Sidney studies for the exam." A: "practices" is correct as it agrees with the subject Jack. B: "while" is used correctly as a conjunction to show simultaneous actions. D: "exam" is used correctly as the object of the preposition "for."

Correct Answer: A

Rationale: The correct answer is A: Period. A period is needed at the end of the sentence to indicate a complete thought and signal the end of the sentence. In this case, the sentence is a simple statement, so a period is the appropriate punctuation mark. The other choices are incorrect because a comma (B) would create a comma splice, a colon (C) would be unnecessary as the sentence is not introducing a list or explanation, and a semicolon (D) would be too strong of a punctuation mark for this context.

Correct Answer: C

Rationale: The correct answer is C: her. In this sentence, "Roseanne" is a singular noun, so the possessive pronoun "her" should be used to show ownership. "She" (choice A) is a subject pronoun, "their" (choice B) is a plural pronoun, and "hers" (choice D) is a possessive pronoun used without a noun. Therefore, "her" is the most suitable choice to maintain clarity and grammatical correctness.
