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. Why did Macmillan add iron rims to the tires of his bicycle?

A. Increase the weight of the bicycle.
B. Enhance the durability of the tires.
C. Reduce the bumpiness of the ride.
D. Decrease the level of fatigue during the ride.

Correct answer: B

Rationale: Macmillan added iron rims to his bicycle tires to enhance their durability and make them last longer. This innovation aimed to prevent the tires from getting worn down quickly. Adding weight to the bicycle (Choice A) was not the purpose of adding iron rims. While adding iron rims could potentially reduce the bumpiness of the ride (Choice C) by providing more stability, the main objective was to improve tire longevity. Similarly, reducing the level of fatigue during the ride (Choice D) was not the primary reason for adding iron rims.

4. Which rainforest plant has more than one use?

A. The Buruti plant
B. The Banana tree
C. The Cinnamon tree
D. The Coconut tree

Correct answer: A

Rationale: The correct answer is the Buruti plant. The passage mentions that Amazonian Indians use the fruit and stem of the Buruti plant for various purposes, such as a drink, making bread, and building houses. The other choices, Banana tree, Cinnamon tree, and Coconut tree, are not specifically mentioned as having multiple uses in the passage. While the passage does mention that bananas and coconuts are available as food in the rainforest, it does not specify multiple uses for these plants as it does for the Buruti plant.

5. What is the meaning of the word 'established' as used in the first paragraph?

A. Created
B. Ascertained
C. Founded
D. Reputable

Correct answer: C

Rationale: In this context, 'established' means 'founded' or set up for a long time. The word is used to indicate that phototherapy has been a recognized and in place form of medicine for over a century. 'Created' (choice A) is incorrect as it implies the initial invention of phototherapy, which is not the intended meaning here. 'Ascertained' (choice B) means to find out for certain, which does not match the context of how phototherapy has been practiced. 'Reputable' (choice D) means having a good reputation, which is not the same as being long-standing or founded.
