Reading Comprehension Practice Test HESI A2

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

A. To inform.
B. To persuade.
C. To entertain.
D. To analyze.

Correct answer: D

Rationale: The primary purpose of the essay is to inform the reader about concussions, their effects, and recovery. While analysis may be involved in the presentation, the overarching goal is to provide information, making A the most accurate answer.

2. What is the meaning of the word 'emitting' as it is used in the second paragraph?

A. Repelling
B. Releasing
C. Closing
D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.

3. Which statement from the passage on Voice is a fact rather than an opinion?

A. One of the worst voice qualities is harshness.
B. Harsh voice qualities come from tension in the throat.
C. Your voice will sound unpleasant if it is shrill or grating.
D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Correct answer: B

Rationale: The correct answer is B. The fact that harsh voice qualities come from tension in the throat is a verifiable statement based on a scientific explanation provided in the passage. This statement is not subject to personal interpretation or judgment. Choice A is an opinion as it categorizes harshness as one of the worst voice qualities, which is subjective. Choice C is also an opinion as it describes how a voice will sound based on subjective terms like 'unpleasant.' Choice D is an opinion as it makes a generalized statement linking higher-pitched voices with shriller voices in women, which can vary widely among individuals.

4. What is the meaning of the word overturn in the last paragraph of the passage?

A. Justify
B. Invalidate
C. Support
D. Review

Correct answer: B

Rationale: The word "overturn" means to invalidate or negate existing guidelines. In this context, the passage questions whether the findings of the study are substantial enough to change established medical recommendations regarding caffeine intake during pregnancy, making option B the appropriate choice.

5. Which statement is not a detail from the passage?

A. Condensation fails to happen when water vapor cools and changes back into droplets of liquid
B. Evaporation happens when water changes into gas
C. The water cycle does not involve precipitation
D. Water evaporates from oceans and rivers

Correct answer: C

Rationale: Choice C, 'The water cycle does not involve precipitation,' is not a detail from the passage. The passage clearly states that precipitation, such as rain, snow, sleet, or hail, is a crucial part of the water cycle. On the other hand, choices A, B, and D are all supported by the passage. Condensation occurs when water vapor cools, evaporation occurs when water changes into gas, and water evaporates from oceans and rivers are all mentioned in the text.
