HESI A2

Reading Comprehension HESI A2

1. What body of water does The Golden Gate Bridge cross?

A. San Francisco Bay
B. Pacific Ocean
C. Marin Strait
D. Indian Ocean

Correct answer: A

Rationale: The Golden Gate Bridge crosses the entrance to San Francisco Bay, spanning the Golden Gate Strait. It does not cross the Pacific Ocean, Marin Strait, or Indian Ocean directly. The iconic bridge connects the city of San Francisco to Marin County in California. The Pacific Ocean is a vast body of water beyond the Golden Gate entrance, and Marin Strait is not a recognized geographical location. The Indian Ocean is located on a different continent and is not related to the Golden Gate Bridge's location.

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

A. Chance
B. Persistence
C. Foreboding
D. Expertise

Rationale: The word "serendipity" refers to a fortunate coincidence or chance, describing how Beto Pérez invented Zumba accidentally.

3. What statement about global warming is made in the passage on the Amazon Rainforest?

A. Global warming is caused by deforestation.
B. Global warming is unrelated to deforestation.
C. Global warming is exaggerated.
D. Global warming is not a concern.

Correct answer: A

Rationale: The correct statement about global warming in the passage on the Amazon Rainforest is that it is caused by deforestation. The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year. Choice B is incorrect as the passage clearly establishes a direct link between deforestation and global warming. Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation. Choice D is incorrect as the passage emphasizes the serious concern of global warming due to deforestation.

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. 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.
