HESI A2 Grammar Practice Exam

Correct Answer: A

Rationale: The correct answer is A: principle. In the sentence, the word should be "principal" to refer to the main or leading role. "Principle" refers to a fundamental truth or belief. The other choices, B: role, C: provision, and D: convenient are all spelled correctly and fit appropriately in the sentence context.

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 punctuation needed in the sentence is a comma. A comma is used to separate two independent clauses when they are joined by a coordinating conjunction (such as "and" in this case). In the given sentence, "In addition to the hospital's regularly scheduled festivities" and "the custodians celebrate with a party of their own" are two independent clauses joined by "In addition to." Therefore, a comma is needed before the coordinating conjunction "In addition to" to make the sentence grammatically correct. Choice A (Period) is incorrect because a period would create two separate sentences, which is not the intended structure. Choice C (Apostrophe) is incorrect as there is no possessive form being used in the sentence. Choice D (Semicolon) is incorrect as a semicolon is not necessary to join these two independent clauses when a coordinating conjunction is present.

Correct Answer: C

Rationale: The correct answer is C: them. In the sentence, "The children and them performed a skit for the elderly patients," the pronoun "them" is used to refer to a group of people (children and others). The pronoun "them" is the objective form of the pronoun "they" and is used to represent the object of the sentence. In this case, the children and other individuals are the ones performing the skit, making "them" the appropriate choice. Choice A: "he" is incorrect as it would refer to a singular male individual, not a group. Choice B: "me" is incorrect as it is the objective form of the pronoun "I" and does not fit the subject of the sentence. Choice D: "her" is incorrect as it is the objective form of the pronoun "she" and does not match the subject of the sentence.

Correct Answer: B

Rationale: The correct answer is B: infer. In the sentence, "infer" is used incorrectly. The word "infer" means to deduce or conclude information based on evidence or reasoning, while in the sentence, it should be "imply" as it is the speaker who is suggesting something through the grimace. The other choices (A, C, D) are used correctly in the context of the sentence. A grimace is a facial expression of disgust or pain, "loathed" means strongly disliked, and "performance" refers to a presentation or show.
