HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: Concave means curving inward, creating a hollow or "caved-in" shape. So, choice A "Rounded inward" is correct. Choice B "Rounded outward" is incorrect as it describes a convex shape. Choice C "Straight" is incorrect as concave implies a curved surface. Choice D "Flat" is incorrect as it does not describe a curved shape.

Correct Answer: A

Rationale: The correct answer is A because "the thief" indicates a singular person, so the pronoun "he" should be used. The subject-verb agreement is crucial in this sentence. Choice B uses "he" correctly but includes a different verb. Choices C and D use the incorrect pronoun "they," which does not agree with "the thief." Additionally, "hid" in choice C is not the appropriate action after robbing a bank, and "fled" in choice D is plural and doesn't match with "the thief." Therefore, option A is the correct choice based on subject-verb agreement and logical consistency.

Correct Answer: B

Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated. Innovation (A) means introducing something new, effective (C) means successful in producing a desired or intended result, and advanced (D) means at a higher level of progress or development. In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.

Correct Answer: B

Rationale: The correct answer is B: Wide open. "Gaping" typically refers to something being wide open or having a large opening. This can be inferred from the word itself, as "gaping" implies a significant space or opening. Choices A, C, and D are incorrect because they do not align with the typical meaning of "gaping." A (Partially closed) suggests the opposite of what "gaping" means, C (Narrow) implies a small opening rather than a wide one, and D (Sealed) indicates something being completely closed rather than open. By process of elimination and understanding the definition of "gaping," the correct answer is B.

Correct Answer: C

Rationale: The correct answer is C: Ephemeral. The word "ephemeral" means lasting for a very short time, which accurately describes a trip that the vacationer felt was too short. "Ponderous" means slow and dull, "salacious" means lustful or obscene, and "erudite" means scholarly or knowledgeable, none of which accurately describe a short trip. Therefore, C is the best choice.
