Reading Comprehension HESI A2 Practice Test

1. Choose the best summary of the passage about microbes.

Correct answer: C

Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.

2. What is the passage primarily about?

Correct answer: A

Rationale: The correct answer is A: 'What we know about the Moon and its differences from Earth.' The passage discusses various aspects of the Moon, including its origin, gravitational influence on Earth, physical characteristics, lack of atmosphere, and surface features. It provides insights into what humans know about the Moon and highlights its differences from Earth. Choice B is incorrect because while the passage does compare certain aspects of the Moon and Earth, it primarily focuses on the Moon itself rather than a direct comparison. Choice C is incorrect as the passage briefly mentions the Moon's effect on Earth in relation to tides but does not primarily focus on this aspect. Choice D is incorrect as the origin of the Moon is mentioned in the passage, but it is not the primary focus of the text.

3. What is the meaning of the word 'elasticity' in the last paragraph?

Correct answer: A

Rationale: 'Elasticity' refers to the ability of the arterial walls to resist and be flexible, which affects blood pressure. In the provided extract, it is mentioned that an increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. This demonstrates that elasticity refers to the property of being able to resist and be flexible, supporting choice A as the correct answer. The other choices, B, C, and D, do not accurately reflect the concept of elasticity in the context of arterial walls and blood pressure.

4. What would be the best title for this passage?

Correct answer: D

Rationale: The best title for this passage is 'PE for School and Life' as it encapsulates the broader purpose of physical education described in the extract. The passage emphasizes teaching students lifelong fitness habits, instilling lessons about maintaining good health, staying fit, and introducing exercise that can be incorporated into their lives. The focus is on fitness as a lifelong skill rather than just a short-term activity for a good grade. Choice A, 'Being a Team in PE,' is incorrect as the passage highlights individual exercise and movement rather than team-based activities. Choice B, 'A New Kind of Grade,' is also incorrect as the passage mentions a shift in grading towards effort rather than specific performance tasks. Choice C, 'Learning Martial Arts,' is too narrow as the passage discusses a variety of activities beyond martial arts that are taught in modern PE classes.

5. What was the author’s primary purpose for writing this essay?

Correct answer: D

Rationale: The correct answer is D. The author's primary purpose for writing the essay is to inform the reader about the stages of the water cycle. The essay discusses the various stages of the water cycle, including precipitation, runoff, evaporation, and condensation. Choices A, B, and C are incorrect because the essay focuses on explaining the water cycle stages rather than persuading the reader to conserve water, discussing the effectiveness of runoff, or analyzing different types of runoff.
