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.

B. Saturated fats are more calorically dense than unsaturated fats.
C. Trans fats are more calorically dense than saturated fats.
D. Unsaturated fats are mostly found in animal products.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.
