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 statement from the article is correct?

A. Chopsticks were developed in Europe.
B. China developed chopsticks for eating utensils.
C. Eating with forks is difficult.
D. Space travel eliminated the need for utensils.

Correct answer: B

Rationale: The correct answer is B. The passage clearly states that China developed chopsticks as an efficient tool for eating, making choice B the correct statement. Choice A is incorrect as chopsticks were not developed in Europe but in China. Choice C is not supported by the passage as it does not discuss the difficulty of eating with forks. Choice D is also incorrect as space travel introduced new challenges but did not eliminate the need for utensils.

3. What conclusion can be drawn from the passage on the Amazon Rainforest?

A. The Amazon Rainforest is shrinking at a rapid pace.
B. The Amazon Rainforest is not affected by human activity.
C. The Amazon Rainforest will survive indefinitely.
D. The Amazon Rainforest has no significant impact on global warming.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage on the Amazon Rainforest is that it is shrinking at a rapid pace. The passage explicitly mentions the rapid deforestation and shrinking of the Amazon Rainforest due to human activities like logging and burning. This conclusion is supported by the alarming statistics provided, such as 9,169 square miles of forest being cut down in Brazil in 2003, and an area of rainforest the size of a football field being burned down every minute. This rapid destruction poses a significant threat to the survival of the Amazon Rainforest and its biodiversity. Choice B is incorrect as the passage clearly states that human activities are causing harm to the rainforest. Choice C is incorrect because the passage highlights the current dangers and threats faced by the Amazon Rainforest, indicating that its survival is at risk. Choice D is also incorrect as the passage clearly explains the significant impact of deforestation in the Amazon Rainforest on global warming due to the release of carbon dioxide into the atmosphere.

4. Which of the following statements is an opinion?

A. The connection between sleep and weight should be explored.
B. Many young children average only eight hours of sleep a night.
C. People who sleep less are more likely to be obese.
D. Researchers in New Zealand studied almost 600 children.

Correct answer: A

Rationale: The statement that the connection between sleep and weight should be explored reflects a personal viewpoint rather than an objective fact. It indicates a belief that further research is warranted to understand this relationship better, making it an opinion and distinguishing it from the other factual statements presented in the passage.

5. What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches?

A. At the nanoscale, metals are rigid, and at larger scales, they are bendable.
B. Matter has different and special characteristics at the nanoscale.
C. At the nanoscale, matter has different properties than matter at the atomic level.
D. There is no difference.

Correct answer: B

Rationale: The correct answer is B. Matter at the nanoscale exhibits unique and special characteristics that distinguish it from matter at larger scales. This can include properties like increased surface area, different melting points, altered conductivity, and enhanced reactivity. Choice A is incorrect as metals at the nanoscale can be more rigid compared to their larger scale counterparts. Choice C is incorrect because matter at the nanoscale has properties that are distinct from both atomic and larger scales. Choice D is incorrect as there are significant differences in how matter behaves and interacts at the nanoscale compared to larger scales.
