HESI A2 Reading Comprehension Practice Test

1. What statement about jetlag can be inferred from the passage on Daylight Savings Time?

A. Jetlag is caused by flying at high speeds.
B. Jetlag is caused by moving between time zones.
C. Jetlag is unrelated to time zone changes.
D. Jetlag is a myth.

Correct answer: B

Rationale: The correct answer is B: 'Jetlag is caused by moving between time zones.' The passage explains that jetlag occurs when moving suddenly from one time zone to another, such as when flying from Asia to North America. This disrupts the body's internal clock, leading to symptoms like tiredness and sleep disturbances. Choice A is incorrect as jetlag is not attributed to high-speed travel but to time zone changes. Choice C is incorrect as the passage clearly links jetlag to changes in time zones. Choice D is incorrect as jetlag is a real phenomenon experienced by individuals who travel across different time zones.

2. What is the meaning of the word 'ideal' as it is used in the first paragraph?

A. thoughtful
B. confined
C. hostile
D. perfect

Correct answer: D

Rationale: In this context, 'ideal' means perfect. The human body provides a perfect environment for many microbes, as stated in the extract. It is the immune system's role to keep these microbes out or destroy them. The other choices are incorrect: 'thoughtful' does not fit the context of the sentence, 'confined' and 'hostile' are not synonymous with 'ideal' in this context.

3. What is stated in the passage about Sleep Apnea?

A. Sleep apnea causes chronic illness.
B. Sleep apnea affects intellectual abilities.
C. Sleep apnea leads to early death.
D. Sleep apnea causes breathing interruptions.

Correct answer: D

Rationale: The correct answer is 'D: Sleep apnea causes breathing interruptions.' The passage explicitly mentions sleep apnea as a condition where an individual stops breathing during sleep, indicating breathing interruptions. Choice A is incorrect because the passage does not directly state that sleep apnea causes chronic illness. Choice B is incorrect because the passage discusses how lack of sleep affects intellectual abilities but does not specifically attribute this to sleep apnea. Choice C is incorrect as the passage does not mention sleep apnea leading to early death. Therefore, the most accurate statement about sleep apnea based on the passage is that it causes breathing interruptions.

4. What is the author's reason for writing the passage on the White Elephant?

A. To inform readers about Thailand's historical customs.
B. To entertain readers with the origins of the term 'white elephant.'
C. To explain the tradition of giving white elephants.
D. To criticize the tradition of giving white elephants as gifts.

Correct answer: C

Rationale: The correct answer is C: 'To explain the tradition of giving white elephants.' The passage provides historical context about the practice of giving white elephants as gifts in ancient Siam, now Thailand. It explains how white elephants were considered sacred, could not be put to work, and became a burden to the recipients. The author's purpose is to shed light on this tradition and its implications, not to inform readers about Thailand in general (choice A), entertain with fun facts (choice B), or criticize the tradition (choice D). Choices A and B are incorrect because the passage focuses specifically on the tradition of giving white elephants, not on broader aspects of Thailand or entertainment. Choice D is incorrect because the passage does not criticize the tradition but rather provides a factual account of its historical significance.

5. As used in the last sentence of this paragraph, the term 'concomitant' means?

A. Accompanying
B. Quiet
C. Frustrated
D. Prefer low-pitched tones

Correct answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.
