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.

2. What is the meaning of the word moderation as used in the second paragraph?

A. Adequate amounts
B. Intervals of time
C. Excess
D. Variation

Correct answer: A

Rationale: In this context, moderation means consuming adequate amounts of unsaturated fats. The passage highlights that unsaturated fats like olive oil and omega-3 fatty acids are beneficial when consumed in appropriate quantities. Choice B, intervals of time, is incorrect as it does not relate to the consumption of fats. Choice C, excess, is incorrect because moderation implies avoiding excess consumption. Choice D, variation, is unrelated to the context of consuming fats in appropriate amounts.

3. Which statement would not be inferred by the reader in the passage about Super Foods?

A. Instant oatmeal can be part of a healthful breakfast.
B. Blueberries are an especially healthful food.
C. Certain grains and dairy products are super foods.
D. Super foods are more expensive than processed foods.

Correct answer: D

Rationale: The passage does not imply or provide information regarding the cost of superfoods compared to processed foods. Therefore, D is the correct answer, as it identifies a statement that cannot be inferred from the passage.

4. What can be inferred from the passage about Daylight Savings Time?

A. It is primarily used to save energy during certain months.
B. It was universally accepted upon its introduction.
C. The US government opposed the idea initially.
D. It was implemented to prevent jetlag.

Correct answer: A

Rationale: The correct answer is A: "It is primarily used to save energy during certain months." The passage clearly states that Daylight Savings Time was first put into practice by the German government in 1916 to save energy during the First World War. The US followed suit in 1918. This measure was unpopular initially, but the energy crisis in the 1970s led to making it a law. Choices B, C, and D are incorrect. Choice B is incorrect as the passage mentions that the British government initially refused the idea, and it was unpopular when first implemented. Choice C is incorrect as it was not the US but the British government that opposed the idea initially. Choice D is incorrect as Daylight Savings Time was not implemented to prevent jetlag, but rather to save energy and make better use of daylight hours.
