HESI A2 Reading Comprehension V1 2024
1. Which sound waves have a higher pitch?
- A. Those waves that are closer together
- B. Those waves that are farther apart
- C. Those waves that travel a long distance
- D. Those waves that travel a short distance
Correct answer: A
Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.
2. What is the meaning of the word 'popular' as it is used in the third paragraph?
- A. complicated
- B. old-fashioned
- C. beloved
- D. for the general public
Correct answer: D
Rationale: In the context provided, 'popular' refers to magazines intended for the general public. The paragraph mentions that Infotrac indexes hundreds of popular magazines and newspapers, including medical journals such as the Journal of the American Medical Association and New England Journal of Medicine. These magazines target a wide audience, making choice D ('for the general public') the correct answer. Choices A, B, and C are incorrect as they do not align with the context of the paragraph.
3. 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.
4. What fact is stated about the Amazon Rainforest in the passage?
- A. The Amazon Rainforest is shrinking rapidly.
- B. The Amazon Rainforest is home to diverse species.
- C. The Amazon Rainforest is unaffected by human activity.
- D. The Amazon Rainforest contains few animals.
Correct answer: B
Rationale: The correct answer is B. The passage highlights the incredible biodiversity of the Amazon Rainforest, emphasizing its diverse species of plants and animals. The passage describes the rainforest as home to over 2,000 birds and mammals, with one in every five birds in the world living there. It also mentions the vast variety of insects, trees, and plants present in the rainforest, showcasing its rich ecosystem. Choice A is incorrect as the passage does not directly state that the Amazon Rainforest is shrinking rapidly, although it does mention the dangers it faces. Choice C is incorrect as the passage clearly indicates that human activity, such as deforestation, poses a significant threat to the rainforest. Choice D is incorrect as the passage provides evidence of a high number of animals inhabiting the Amazon Rainforest.
5. The passage mentions all of these uses for microscopy EXCEPT ___________.
- A. Ear surgery
- B. Amputations
- C. Vasectomies
- D. Reconstructions
Correct answer: C
Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.
