Reading Comprehension HESI A2 Practice Test

1. What is the author’s primary purpose in writing this essay about microbes?

Correct answer: B

Rationale: The author's primary purpose is to inform readers about the crucial role of microorganisms in the immune system. The essay focuses on presenting factual information and recent discoveries regarding the impact of microbes on human health. The author aims to educate the readers on the significance of microbes in human health rather than persuade them of a particular viewpoint (Choice A), entertain them with light-hearted content (Choice C), or analyze in-depth data and findings (Choice D). The essay's emphasis on informing readers about the role of microorganisms in the immune system makes 'To inform' the correct choice.

2. What body of water does The Golden Gate Bridge cross?

Correct answer: A

Rationale: The Golden Gate Bridge crosses the entrance to San Francisco Bay, spanning the Golden Gate Strait. It does not cross the Pacific Ocean, Marin Strait, or Indian Ocean directly. The iconic bridge connects the city of San Francisco to Marin County in California. The Pacific Ocean is a vast body of water beyond the Golden Gate entrance, and Marin Strait is not a recognized geographical location. The Indian Ocean is located on a different continent and is not related to the Golden Gate Bridge's location.

3. As used in the last sentence of this paragraph, the term 'concomitant' means?

Correct answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.

4. The passage explicitly states?

Correct answer: A

Rationale: The correct answer is A: 'That the highest card within the 'trump' suit always wins the trick.' The passage explicitly mentions that in the game of Bridge, if a player plays a card from the trump suit, it always wins the trick. This detail is clearly stated in the text, making it the correct choice. Choice B is incorrect as there is no mention of a pile of leftover cards in the passage. Choice C is incorrect as the passage does not state that a player loses their turn if they cannot follow suit; instead, they play any card. Choice D is incorrect as the passage states that the ace is high, not low.

5. What does the term elasticity mean, as used in the passage about Hypertension?

Correct answer: C

Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.
