HESI A2 Reading Comprehension V2 2024

Correct Answer: D

Rationale: The correct answer is D: Faulty. In the passage, the word 'defective' is used to describe something that is not working correctly or has a fault. This aligns with the definition of 'faulty', making it the most suitable choice. A: Unusual - This choice does not accurately reflect the meaning of 'defective' in the context of the passage. B: Remarkable - This choice is not related to the meaning of 'defective' as it implies something positive or exceptional. C: Postponed - This choice is unrelated to the meaning of 'defective' in the passage, as it refers to delaying or rescheduling, which is not the intended meaning. Therefore, D: Faulty is the correct choice as it best captures the meaning of 'defective' in the context provided.

Correct Answer: B

Rationale: The correct answer is B because matter at the nanoscale exhibits unique properties due to quantum effects and surface area-to-volume ratio. At this scale, materials can have altered chemical, mechanical, and optical properties compared to macroscopic scales. Choice A is incorrect because the flexibility of metals does not solely depend on scale. Choice C is incorrect as nanoscale properties are influenced by atomic-level interactions. Choice D is incorrect as the nanoscale does have distinct characteristics.

Correct Answer: D

Rationale: The correct answer is D: Faulty. In the passage, the word 'defective' is used to describe something that is not working correctly or has a fault. This aligns with the definition of 'faulty', making it the most suitable choice. A: Unusual - This choice does not accurately reflect the meaning of 'defective' in the context of the passage. B: Remarkable - This choice is not related to the meaning of 'defective' as it implies something positive or exceptional. C: Postponed - This choice is unrelated to the meaning of 'defective' in the passage, as it refers to delaying or rescheduling, which is not the intended meaning. Therefore, D: Faulty is the correct choice as it best captures the meaning of 'defective' in the context provided.

Correct Answer: D

Rationale: The correct answer is D because nanotechnology deals with materials at the nanoscale, where unique properties emerge due to quantum effects. This allows for the development of innovative products with enhanced characteristics. Choice A is too broad and does not specifically address the benefits of nanotechnology. Choice B simply defines nanotechnology but does not focus on its benefits. Choice C mentions a specific application of nanotechnology but does not capture the broad range of benefits that nanotechnology offers.

Correct Answer: D

Rationale: The correct answer is D: For safety. Strauss set up a safety net to protect workers in case of falls during the construction of the Golden Gate Bridge. This precautionary measure was essential to prevent injuries and fatalities. The other choices are incorrect because: A) Suspension is not related to setting up a net, B) Balance does not require a safety net, and C) Aesthetics are not a primary concern when it comes to worker safety.
