Grammar HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: Period. In the sentence "Take this fast-acting cough medicine after your next meal," a period is needed at the end to indicate the end of a complete thought or sentence. A period is used to separate sentences and is essential for clarity and proper grammar. Explanation for other choices: B: Comma - A comma is not appropriate at the end of a sentence unless it is part of a list or used for a specific grammatical structure. C: Colon - A colon is used to introduce a list or an explanation, neither of which is needed in this sentence. D: Hyphen - A hyphen is used to join words together or to separate syllables, neither of which is necessary in this context.

Correct Answer: B

Rationale: The correct answer is B: taking. In this sentence, the word "Before" indicates that the action of consuming a modest meal should happen prior to another action. The gerund form "taking" correctly conveys this sequence of events. Choice A, "having taken," implies a past action that is already completed, which does not fit the context. Choice C, "took," is in the past tense and does not align with the timing indicated by "Before." Choice D, "will take," suggests a future action, which is not appropriate in this sentence.

Correct Answer: A

Rationale: The correct answer is A: his. In the sentence, "his" is used to indicate possession, showing that the relatives belong to Mr. Karnicki. Choice B (theirs) is incorrect because it implies the relatives own something, which is not the meaning intended. Choice C (them) is incorrect as it refers to the relatives themselves rather than their belonging to Mr. Karnicki. Choice D (their) is incorrect because it is a possessive pronoun but lacks the specific reference to Mr. Karnicki as the owner. Therefore, "his" is the best choice as it correctly shows possession by Mr. Karnicki.

Correct Answer: C

Rationale: The correct answer is C: Although. In the sentence, the word "although" is used to contrast two ideas - Octavia being the youngest but still taller than her classmates. This conjunction helps to show the unexpected relationship between her age and height. The word "despite" (A) would imply a sense of contradiction, but the sentence does not present two conflicting ideas. "Since" (B) implies a cause-and-effect relationship, which is not the intended meaning here. "Provided" (D) suggests a condition or stipulation, which does not align with the context of the sentence.

Correct Answer: C

Rationale: The correct answer is C: never seen. The phrase "never seen" is not grammatically correct in this sentence as it should be "had never seen." The past perfect tense "had never seen" is used to indicate an action that did not occur before a certain point in the past, which fits the context of Javier's trip to Puerto Rico. The other choices, A: Until his trip, B: had never, and D: his ancestral home, are all used correctly in the sentence.
