HESI A2 Reading Comprehension Practice Test

Correct Answer: A

Rationale: The correct answer is A because the passage specifically mentions the impact of deforestation on global warming in the context of the Amazon Rainforest. Deforestation leads to the release of stored carbon dioxide, a greenhouse gas, into the atmosphere, contributing to global warming. The other choices are incorrect because the passage does not state that global warming is unrelated to deforestation (B), exaggerated (C), or not a concern (D). Therefore, option A is the most directly supported by the information provided in the passage.

Correct Answer: D

Rationale: The correct answer is D because the passage explicitly states that sleep apnea causes breathing interruptions. This is a direct and clear statement supported by the text. The passage does not mention chronic illness, intellectual abilities, or early death in relation to sleep apnea, so choices A, B, and C are incorrect. It is important to focus on information directly stated in the passage to determine the correct answer.

Correct Answer: B

Rationale: The correct answer is B because it presents a verifiable statement about the cause of harsh voice qualities, linking them to tension in the throat. This can be objectively observed and measured. In contrast, choices A, C, and D involve subjective judgments or generalizations that cannot be definitively proven as facts. Choice A is subjective as "worst" is a value judgment. Choice C involves subjective terms like "unpleasant," which can vary based on personal preferences. Choice D is a generalization about voice qualities based on gender, which may not apply universally. Thus, B is the only choice that presents a factual statement supported by objective evidence.

Correct Answer: B

Rationale: The correct answer is B: Water vapor plays a key role in precipitation. In the water cycle, water vapor is essential as it evaporates from bodies of water, condenses into clouds, and eventually falls back to the Earth as precipitation. This process is crucial for replenishing water sources on Earth. Choice A is incorrect because water vapor is a fundamental component of the water cycle. Choice C is incorrect as water vapor is a natural part of the atmosphere. Choice D is incorrect because while water vapor can contribute to cooling through processes like evaporation, its primary role in the water cycle is related to precipitation.

Correct Answer: B

Rationale: The correct answer is B: To explain how the Electoral College works. The passage likely focuses on describing the process, function, and purpose of the Electoral College, rather than criticizing, advocating for abolishing, or promoting its benefits. By explaining how it works, the author provides readers with a clear understanding of this system. This choice aligns with the main objective of informing the audience about the Electoral College's mechanisms.
