HESI A2 Reading Comprehension Practice Test

1. What is the main idea of the passage on Daylight Savings Time?

A. Daylight Savings Time helps save energy.
B. Daylight Savings Time is unnecessary and outdated.
C. Daylight Savings Time is a law to conserve energy during wars.
D. Daylight Savings Time was first implemented in Germany.

Correct answer: A

Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.

2. The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

A. A carpenter uses wood glue to fix a broken cabinet.
B. A student buys a new notebook for upcoming classes.
C. A chef sharpens knives before starting to cook.
D. An athlete stretches before a game to avoid a potential injury.

Correct answer: D

Rationale: The correct analogy for the role of corrective lenses in helping aging eyes can be compared to an athlete stretching before a game. Just as stretching prepares an athlete's body to perform optimally and avoid injury during a game, corrective lenses help aging eyes adjust and focus properly due to the hardening and loss of elasticity in the eye lens. Choices A, B, and C do not align with the concept of preparing or adjusting to address a specific issue, unlike the use of corrective lenses for aging eyes.
