HESI A2 Reading Comprehension Practice Test Questions
Question 1 of 5
What is implied about the rainforest's role in global climate?
Correct Answer: B
Rationale: The correct answer is B because the rainforest plays a crucial role in regulating the climate. It acts as a carbon sink by absorbing carbon dioxide from the atmosphere through photosynthesis, helping to mitigate climate change. Additionally, the rainforest influences global weather patterns and water cycles. Incorrect Choices: A: The rainforest actually has a significant impact on the climate due to its role in carbon sequestration. C: While biodiversity is an important aspect of rainforests, their role in climate regulation is equally significant. D: The destruction of rainforests has severe global consequences, including contributing to climate change and loss of biodiversity.
Question 2 of 5
What is the main idea of the passage on Daylight Savings Time?
Correct Answer: A
Rationale: The correct answer is A because the main idea of the passage on Daylight Savings Time is that it helps save energy. Daylight Savings Time adjusts the clocks to make better use of daylight, reducing the need for artificial lighting and heating, thus saving energy. Choice B is incorrect as it presents a biased opinion against Daylight Savings Time without considering its energy-saving benefits. Choice C is incorrect as it inaccurately states that Daylight Savings Time is solely a law for energy conservation during wars. Choice D is incorrect as it provides irrelevant historical information about the origin of Daylight Savings Time, which is not the main idea of the passage.
Question 3 of 5
What was the most dangerous part of building the Golden Gate Bridge?
Correct Answer: A
Rationale: The correct answer is A: Balancing the road to prevent collapse. This was the most dangerous part because achieving balance was crucial to prevent the bridge from collapsing under its own weight. It required precise calculations and adjustments to ensure stability. Incorrect choices: B: Constructing the towers due to their height - While constructing the towers was challenging, it was not the most dangerous part as the engineering and construction methods were well-established. C: Suspending the cables with difficulty - Although suspending the cables was complex, it was not as dangerous as ensuring the overall balance of the bridge. D: Ensuring the critical balance of the bridge - This choice is similar to the correct answer but lacks specificity regarding the road's balance, which was the most critical aspect.
Question 4 of 5
What does sleep apnea cause?
Correct Answer: A
Rationale: The correct answer is A: Chronic illness. Sleep apnea causes interruptions in breathing during sleep, leading to reduced oxygen supply to the body. This can result in various chronic illnesses such as hypertension, heart disease, stroke, and diabetes. The other choices are incorrect because sleep apnea does not promote good sleep (choice B), improve memory (choice C), or reduce physical illness (choice D). In fact, untreated sleep apnea can significantly impact overall health and quality of life due to the associated chronic health conditions.
Question 5 of 5
What does the word 'composed' mean in the passage on the Water Cycle?
Correct Answer: A
Rationale: The correct answer is A: To consist of. In the context of the Water Cycle passage, 'composed' refers to the various elements or components that make up a system. The water cycle involves different stages and processes that consist of water in different forms such as vapor, liquid, and ice. This aligns with the definition of 'composed' as to consist of. Explanation for why the other choices are incorrect: B: To create - This does not accurately reflect the meaning of 'composed' in the context of the Water Cycle passage. The water cycle does not involve the creation of water but rather the movement and transformation of existing water. C: To separate - This choice is the opposite of the correct meaning. 'Composed' implies elements coming together, not being separated. D: To destroy - This choice is also the opposite of the correct meaning. The water cycle does not involve destruction but rather a continuous cycle of water moving through different forms.
