HESI A2 Reading Comprehension Practice Test

1. What does the passage about the Water Cycle explain?

A. The water cycle consists of precipitation, evaporation, and condensation.
B. The water cycle is a continuous process of recycling water on Earth.
C. Rain is the most important part of the water cycle.
D. Evaporation is the final step in the water cycle.

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, starting with precipitation (rain, snow, sleet, or hail) falling to the ground, followed by runoff, evaporation transforming liquid water into water vapor, and finally condensation turning water vapor back into liquid. Choice B is incorrect because it is too broad and doesn't specifically address the stages of the water cycle. Choice C is incorrect as rain is just one part of the water cycle and not the most important. Choice D is incorrect as evaporation is not the final step but one of the stages of the water cycle.

2. What is the passage primarily about?

A. What we know about the Moon and its differences from Earth
B. A comparison of the Moon and Earth
C. The Moon’s effect on Earth
D. The origin of the Moon

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. Choose the best summary of the passage.

A. We often think of all fat as bad, but it is clear that certain fats, especially the more healthful unsaturated fats, are important for bodily function.
B. If you must consume some fat, be sure to choose unsaturated fats such as oils rather than saturated fats found in prepackaged snacks or animal products.
C. Doctors and researchers have discovered that without the calories found in fat, people would not have functioning metabolisms.
D. Some intake of saturated fat is necessary, but you should stay away from the kind of fat found in fried food, which can lead to heart disease.

Correct answer: A

Rationale: The best summary of the passage emphasizes the importance of certain fats, particularly unsaturated fats, for bodily function. It highlights that after years of negative publicity, experts now recognize the significance of consuming fats for overall health. The passage discusses how fat is essential for cell health, vitamin absorption, and various bodily functions. It also distinguishes between healthier unsaturated fats like olive oil and detrimental trans fats. Choice B is not the best summary as it focuses more on the choice between unsaturated and saturated fats rather than the overall importance of fats. Choice C is incorrect as the passage doesn't solely attribute functioning metabolisms to fat calories. Choice D is not the best summary as it only briefly mentions saturated fats and fried foods, missing the broader context provided in the passage.

4. What does the word 'suit' mean in the passage about Bridge?

A. A set of clothing to be worn together.
B. Any of the four sets into which a deck of cards is divided.
C. To request or appeal persistently.
D. To be convenient or right for.

Correct answer: B

Rationale: The correct answer is B: 'Any of the four sets into which a deck of cards is divided.' In the context of card games like Bridge, 'suit' refers to one of the four divisions of a deck of cards - spades, hearts, diamonds, or clubs. Each suit contains cards of different ranks, and during the game, players must follow suit if possible, meaning they must play a card of the same suit that was led. This is crucial for understanding card hierarchy and gameplay in Bridge. Choice A is incorrect because it defines 'suit' in terms of clothing, which is not relevant to the context of the passage. Choice C is incorrect as it defines 'suit' as a verb meaning to request persistently, which is unrelated to the card game. Choice D is also incorrect as it defines 'suit' as an adjective meaning to be convenient or right for, which is not the meaning intended in the passage about Bridge.

5. What is the meaning of the word 'pathogens' as it is used in the first paragraph?

A. diseases
B. vaccines
C. disease-causing substances
D. foods

Correct answer: C

Rationale: In the context provided, 'pathogens' refers to disease-causing substances such as bacteria and viruses. These microorganisms can contaminate food and lead to foodborne illnesses. Choice A ('diseases') is incorrect as pathogens themselves cause diseases but are not diseases. Choice B ('vaccines') is incorrect as vaccines are used to prevent diseases caused by pathogens. Choice D ('foods') is incorrect as pathogens are not foods, but rather contaminants that can be found in food.
