HESI A2 Reading Comprehension Practice Test

1. What role does water vapor play in the Water Cycle, as described in the passage?

A. Water vapor is unnecessary in the water cycle.
B. Water vapor plays a key role in precipitation.
C. Water vapor is harmful to the environment.
D. Water vapor cools the Earth's surface.

Correct answer: B

Rationale: The correct answer is B: 'Water vapor plays a key role in precipitation.' The passage clearly outlines the importance of water vapor in the water cycle. It explains that water vapor returns to the air from surface water and plants, and condenses back into droplets of liquid, forming clouds. These clouds eventually lead to precipitation like rain, snow, sleet, or hail. Choice A is incorrect as water vapor is crucial in the water cycle. Choice C is also incorrect as there is no mention of water vapor being harmful in the passage. Choice D is incorrect as the passage does not state that water vapor cools the Earth's surface; instead, it highlights its role in the formation of precipitation.

Correct answer: A

Rationale: The author's primary purpose for writing this essay is to inform the readers about the stages of the water cycle.

The detailed explanation of the water cycle provided in the extract supports the correct answer.

5. Which is the best title for the passage about Hypertension?

A. How to Manage Hypertension Successfully
B. Doctors Discover the Hidden Dangers of Hypertension
C. Doctors Work to Understand the Causes of Hypertension
D. Causes, Symptoms, Complications, and Management of Hypertension

Correct answer: D

Rationale: The best title for the passage about Hypertension is 'Causes, Symptoms, Complications, and Management of Hypertension.' This title accurately reflects the content of the passage, which provides information about the causes, symptoms, complications, and management of hypertension. It covers a broad spectrum of information presented in the passage, making it the most comprehensive and suitable title. Choice A, 'How to Manage Hypertension Successfully,' is too narrow as it focuses solely on management without encompassing the other crucial aspects like causes and symptoms. Choice B, 'Doctors Discover the Hidden Dangers of Hypertension,' is misleading as the passage does not focus on any recent discoveries but rather provides general information about hypertension. Choice C, 'Doctors Work to Understand the Causes of Hypertension,' is also inaccurate as the passage mainly discusses causes, symptoms, complications, and management, rather than doctors' ongoing research efforts.
