HESI A2 Reading Comprehension Practice Test

1. What does the author suggest about the Earth's tilt in the passage on Daylight Savings Time?

A. The Earth's tilt has no effect on the seasons.
B. The Earth's tilt affects the amount of sunlight different areas receive.
C. The Earth's tilt is constant throughout the year.
D. The Earth's tilt changes dramatically during the seasons.

Correct answer: B

Rationale: The author suggests that the Earth's tilt affects the amount of sunlight different areas receive, influencing the seasons. The passage explains how the tilt of the Earth towards the sun results in different regions receiving varying amounts of sunlight, leading to the existence of seasons. This tilt causes regions near the equator to receive more sunlight consistently, while the Poles experience periods of constant darkness or sunlight, creating different seasons. Choices A, C, and D are incorrect because the passage clearly states that the Earth's tilt influences sunlight distribution and subsequently impacts the seasons.

2. What are the three steps of the 'wave of excitation'?

A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.

Correct answer: D

Rationale: The correct steps of the 'wave of excitation' are the excitation of the atrium, excitement of the ventricle, and relaxation of the ventricle. In the described process, the 'wave of excitation' starts with the discharge from the SA node, leading to the excitation of the atrium. Next, the peak ECG corresponds to the excitement of the ventricle, not its relaxation. Finally, the wave concludes with the relaxation of the ventricle, not its contraction. Therefore, choices A, B, and C are incorrect as they do not accurately describe the sequential steps of the 'wave of excitation' as presented in the extract.

3. What is the main idea of the passage about Super Foods?

A. Super foods are low in calories but provide essential nutrients that have enormous health benefits.
B. U.S. supermarkets should make a point of stocking up on powerful super foods.
C. Blueberries are a super food that contains a natural inflammatory as well as important vitamins and minerals.
D. Doctors now believe that daily inclusion of super foods in the diet can reverse the aging process.

Correct answer: A

Rationale: The main idea emphasizes that superfoods are low in calories yet rich in essential nutrients that provide significant health benefits. This statement captures the overall essence of the passage, while the other options focus too narrowly or introduce unsupported claims, making A the correct answer.

4. Which of the following describes the purpose of the passage?

A. To describe the causes of cystic fibrosis
B. To explain how cystic fibrosis is passed down through families
C. To provide an overview of CF and how it is inherited
D. To review why some Americans have CF, but others do not

Correct answer: C

Rationale: The correct answer is C. The passage aims to provide an overview of cystic fibrosis (CF) and how it is inherited. It explains that CF is passed down through families due to a defective gene, detailing how this gene affects the body and who is most commonly affected by the disease. Choices A, B, and D are incorrect because the passage does not solely focus on describing the causes of CF, explaining how it is passed down through families, or reviewing why some Americans have CF while others do not. Instead, it provides a broader perspective on CF and its inheritance.

5. Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

A. HFCS and sugar share a biological structure.
B. HFCS is cheaper to use than sugar.
C. HFCS is now used to sweeten a variety of products.
D. HFCS contains more calories than aspartame.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.
