HESI A2 Grammar Practice Exam

Correct Answer: D

Rationale: The correct answer is D, "inputting." In the sentence, "inputting" is the gerund form of the verb "input," which correctly conveys the ongoing action of Kalinda spending part of her day working with data from the lab. The verb form "inputting" is needed to maintain parallel structure in the sentence. Choice A, "inputs," is incorrect because it is the present tense form of the verb and does not match the sentence structure. Choice B, "input," is incorrect as it is a singular noun and does not convey the continuous action. Choice C, "having input," is incorrect because it introduces unnecessary complexity with the auxiliary verb "having."

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.

Correct Answer: B

Rationale: The correct answer is B: Comma. In the sentence "The days seem long, but the nights seem even longer," a comma is needed before the coordinating conjunction "but" to separate the two independent clauses. This comma helps clarify the relationship between the two contrasting ideas. Choices A, C, and D are incorrect because a period would create two short, choppy sentences, a colon is not needed for this context, and an apostrophe is used for possession or contractions, which are not relevant in this sentence.

Correct Answer: B

Rationale: The correct answer is B: once. In the sentence, "once" is used incorrectly as it implies the professor was only an intern for a brief period in the past, which may not be true. The sentence suggests the professor was an intern at the hospital in the 1980s, not just for a single instance. The other choices (A, C, D) are used correctly in the context of the sentence, as they refer to the profession, role, and location respectively without any ambiguity or error.

Correct Answer: C

Rationale: The correct answer is C: "and new tires." This phrase is misplaced because it disrupts the parallel structure of the sentence. The sentence is about the car's characteristics (white roof) and ownership (belongs to our friends). The phrase "and new tires" should follow the white roof to maintain parallelism. Choices A, B, and D are all correctly placed within the sentence and contribute to its clarity and coherence.
