Reading Comprehension HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B: To inform. The author's primary purpose in writing about microbes is to provide factual information and increase the reader's knowledge about the topic. The essay likely presents data, research findings, and explanations to educate the audience. Choice A (To persuade) would focus on convincing the reader to adopt a particular viewpoint, which is not evident in the question. Choice C (To entertain) would aim at amusing or engaging the reader, which is unlikely given the serious nature of the topic. Choice D (To analyze) would involve a detailed examination or interpretation of the topic, which may not be the main objective of the essay.

Correct Answer: B

Rationale: The correct answer is B: guard. In the context of the passage, a watchdog refers to a guardian or protector, reflecting the function of a watchdog in alerting and protecting. "Companion" (A) does not capture the protective role implied by "watchdog." "Manager" (C) and "punisher" (D) are unrelated to the concept of vigilant protection, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is B: Extent. In the context of the last paragraph, "duration" refers to the length or period of time that something lasts. Extent is synonymous with duration as it also indicates the amount of time something continues. Choice A, Basis, is not directly related to the concept of time. Choice C, Cure, and choice D, Solidity, do not align with the meaning of duration in this context. Therefore, B: Extent is the most appropriate choice based on the definition and usage of the word in the paragraph.

Correct Answer: D

Rationale: The correct answer is D because the study likely showed positive results supporting the effectiveness of acupuncture for treating cramps. Acupuncture has been shown to be a reasonable treatment choice for various conditions, including menstrual cramps. The other choices are incorrect because they make assumptions without specific evidence from the study. Choice A is too extreme and dismissive, while choice B is overly optimistic and generalizes the results. Choice C makes a blanket statement without considering individual differences and nuances in treatment effectiveness.

Correct Answer: A

Rationale: Supplementation means adding something extra to enhance or complete something. In the context of the second paragraph, it refers to providing additional support or resources. "Extra" best captures this meaning, making it the correct answer. "Organization" refers to arranging things systematically, not relevant here. "Attachment" means connecting or sticking to something, not the intended meaning. "Revision" implies making changes or corrections, which is not the context of the word in this paragraph.
