HESI A2 Reading Comprehension V2 2024
1. What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches?
- A. At the nanoscale, metals are rigid, and at larger scales, they are bendable.
- B. Matter has different and special characteristics at the nanoscale.
- C. At the nanoscale, matter has different properties than matter at the atomic level.
- D. There is no difference.
Correct answer: B
Rationale: The correct answer is B. Matter at the nanoscale exhibits unique and special characteristics that distinguish it from matter at larger scales. This can include properties like increased surface area, different melting points, altered conductivity, and enhanced reactivity. Choice A is incorrect as metals at the nanoscale can be more rigid compared to their larger scale counterparts. Choice C is incorrect because matter at the nanoscale has properties that are distinct from both atomic and larger scales. Choice D is incorrect as there are significant differences in how matter behaves and interacts at the nanoscale compared to larger scales.
2. What is the main idea of the passage?
- A. Bicycles have become a common mode of transportation worldwide.
- B. The first modern bicycle was invented in 1818 in Germany.
- C. Innovations and improvements in bicycle design have made bicycles popular for recreation and transportation globally.
- D. Bicycles are now built, used, and enjoyed globally.
Correct answer: C
Rationale: The main idea of the passage is that innovations and improvements in bicycle design have made bicycles one of the most popular means of recreation and transportation worldwide. The passage outlines the evolution of bicycles from their early designs to the modern versions, emphasizing how these changes have contributed to their popularity. Choice A is incorrect because it focuses only on the current status of bicycles, while the main idea encompasses the evolution and improvements in design. Choice B is incorrect as it mentions the invention of the first modern bicycle but does not address the overall impact of innovations on bicycle popularity. Choice D is incorrect as it simply states a fact without capturing the essence of the passage, which is about the impact of design improvements.
3. Which claim from the passage best describes the benefits of nanotechnology?
- A. Scientists can develop novel technologies and products.
- B. Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers.
- C. The different colors can be used in simple medical tests to indicate infection or disease.
- D. Unique properties of materials emerge.
Correct answer: D
Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.
4. In context, the word 'defective' in the first sentence of the passage means which of the following?
- A. Unusual
- B. Remarkable
- C. Postponed
- D. Faulty
Correct answer: D
Rationale: In the context provided, 'defective' means faulty, referring to the gene that causes cystic fibrosis (CF). The passage explains that CF is caused by a defective gene, resulting in the production of abnormally thick and sticky fluid. The word 'defective' suggests that the gene is not functioning correctly, leading to the symptoms associated with the disease. Therefore, 'faulty' is the correct choice. The other options, 'unusual,' 'remarkable,' and 'postponed,' do not accurately capture the meaning of 'defective' in this context and are therefore incorrect.
5. Why did Strauss set up a net during the construction of the Golden Gate Bridge?
- A. For suspension
- B. For balance
- C. For aesthetics
- D. For safety
Correct answer: D
Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.
