HESI A2 Grammar Practice Exam

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma (Choice B). The comma is used to separate the dependent clause "Because of a major accident on the freeway" from the independent clause "the emergency room was overcrowded." This creates a clear and correct sentence structure. A period (Choice A) would create two separate sentences, which is not necessary in this case. An exclamation point (Choice C) is inappropriate as the sentence is not expressing excitement or strong emotion. A semicolon (Choice D) is not suitable as the clauses are not closely related or part of a list.

Correct Answer: C

Rationale: The correct answer is C: herself. In the sentence, "Mary Ann gave herself credit for studying so hard and passing the test," the reflexive pronoun "herself" refers back to the subject "Mary Ann." This usage indicates that Mary Ann is giving credit to herself, making the sentence grammatically correct. Choice A (oneself) is incorrect because it is a generic reflexive pronoun that does not agree with the feminine subject "Mary Ann." Choice B (itself) is incorrect because it refers to inanimate objects, not a person like Mary Ann. Choice D (themselves) is incorrect because it is plural and does not agree with the singular subject "Mary Ann."

Correct Answer: B

Rationale: The correct answer is B: between. The preposition "between" is used to show the relationship of two distinct objects or areas. In this case, the sentence is referring to the fountain being located in the space separating the driveway and the main entrance. The prepositions "among," "by way of," and "in conjunction with" do not convey the same meaning as "between" in this context. "Among" is used for three or more objects, "by way of" implies a pathway or route, and "in conjunction with" indicates a cooperative or combined action. Therefore, "between" is the most appropriate choice for the sentence provided.

Correct Answer: C

Rationale: The correct answer is C: understand. In the sentence, the verb "understand" should be followed by a direct object, such as "the essay." However, in this sentence, "the essay" is being used as the object of the preposition "to," making it incorrect. This error affects the sentence structure and clarity. A: pretends - Correctly used as the verb in the sentence. B: truly - Correctly used as an adverb modifying "understand." D: essay - Correctly used as the object of the preposition "to." Summary: "Understand" is the incorrect word as it does not have a direct object in the sentence, affecting the sentence structure and clarity. Other choices are used correctly in the sentence.

Correct Answer: B

Rationale: The correct answer is B: "whose." In the sentence, "whose" is used incorrectly because it is a possessive pronoun indicating ownership, but in this context, it should be "where." The doctor's diploma is not owned by the doctor, but it is located on the partition. The word "where" should be used to show the location of the diploma. A: "That" is used correctly as a demonstrative pronoun referring to the doctor. C: "Hung" is used correctly as the past tense of "hang" to describe the action of placing the diploma on the partition. D: "Partition" is used correctly to refer to the divider where the diploma is hung.
