Reading Comprehension HESI A2 Practice Test

Correct Answer: B

Rationale: The correct answer is B because the passage only discusses information related to humans and their relationship with microbes. It doesn't mention any comparison or contrast between how mice and humans respond to microbes. The other choices are incorrect because they are details explicitly mentioned in the passage, such as babies being born coated with germs from the birth canal, variability in microbial composition among individuals, and the fact that human bodies have more microbes than cells.

Correct Answer: A

Rationale: The correct answer is A because the passage focuses on the critical role of microorganisms in maintaining the immune system. It discusses how recent discoveries have highlighted this importance. Choice B is incorrect as it only mentions the quantity of microorganisms, not their role. Choice C is incorrect as it specifically addresses bacteriotherapy for colon health, not the broader idea of microorganisms and the immune system. Choice D is incorrect as it mentions early research findings but does not align with the main idea of the passage regarding the immune system.

Correct Answer: D

Rationale: The correct answer is D: Native American. The rationale is that the author explicitly mentions cosmetics in Greek, Egyptian, and Roman cultures but does not mention Native American culture. Therefore, based on the information provided, it can be deduced that the author did not describe cosmetics in Native American culture. The other choices (A, B, and C) are incorrect because the author did discuss cosmetics in Greek, Egyptian, and Roman cultures, so they are not the exceptions in this case.

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.

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.
