Reading Comprehension HESI A2 Practice Test

Correct Answer: A

Rationale: The correct answer is A: Reasonable. In the context of the last paragraph, "viable" means capable of working successfully. The word is used to indicate that the solution proposed is practical and likely to be effective. The other choices are incorrect because: B: Unresolved - This suggests that the issue is still pending, which does not fit the context of the paragraph. C: Contemporary - This means modern or current, which is not relevant to the context of the paragraph. D: Consistent - This implies being in agreement or harmony, which is not the intended meaning in the paragraph.

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: Disapproving. The author expresses a negative attitude towards the use of cosmetics by highlighting potential negative effects or societal pressures associated with it. The author's tone may include criticism or disapproval, rather than sympathy, mockery, or tolerance. Sympathetic (A) implies understanding or support, which contradicts the critical tone. Mocking (B) suggests ridicule, which may not be present in the text. Tolerant (C) indicates acceptance, which is not consistent with a negative attitude towards cosmetics.

Correct Answer: B

Rationale: The correct answer is B: Invalidate. In the context of the passage, "overturn" means to overturn or invalidate a decision. This is clear from the surrounding text which discusses challenging a ruling. Justify (A) means to provide a reason for something, not to overturn it. Support (C) means to uphold or back something, which is the opposite of overturning. Review (D) means to assess or evaluate, not necessarily overturn.

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.
