HESI A2 Reading Comprehension Practice Test
1. Why was the roadway of the Golden Gate Bridge so dangerous to build?
- A. It was located above a fast-moving river.
- B. It had to be perfectly balanced to avoid collapse.
- C. The materials used were very unstable.
- D. It was built during bad weather.
Correct answer: B
Rationale: The correct answer is B. The passage describes how the road had to be balanced during construction to avoid collapse into the bay. Choice A is incorrect as the Golden Gate Bridge crosses a strait, not a river. Choice C is incorrect as there is no mention of unstable materials. Choice D is incorrect as bad weather is not highlighted as a specific reason for the danger in building the roadway.
2. Choose the best summary of the passage about microbes.
- A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
- B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
- C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
- D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.
Correct answer: C
Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.
3. 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.
4. What conclusion can be drawn from the article on Eating?
- A. The author thinks chopsticks are funny.
- B. Space flight is fun and exciting.
- C. The author enjoys trying new food.
- D. Diversity is interesting to learn about.
Correct answer: D
Rationale: The correct answer is D. The author highlights cultural diversity and the variety of eating habits in the article. The passage discusses the different eating methods developed by various cultures, such as cutlery in European cultures and chopsticks in China. It emphasizes the interest in discovering these cultural differences and learning new ways of doing things, showcasing the importance of diversity. Choices A, B, and C are incorrect as they do not align with the main focus of the article, which is cultural diversity and eating habits, rather than the author's opinion on chopsticks, space flight, or personal food preferences.
5. What is the meaning of the word 'emitting' as it is used in the second paragraph?
- A. Repelling
- B. Releasing
- C. Closing
- D. Charging
Correct answer: B
Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.
