HESI A2 Reading Comprehension V2 2024

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: 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: Enhance the durability of the tires. By adding iron rims to the tires, Macmillan would have increased the strength and resistance of the tires to wear and tear, making them more durable. This choice aligns with the practical purpose of adding iron rims to bicycle tires, as it would protect the tires from damage and prolong their lifespan. The other choices (A, C, D) do not directly relate to the benefits of adding iron rims to the tires and do not address the primary reason for this modification.

Correct Answer: B

Rationale: The correct answer is B: A ride through the history of bicycles. This title accurately reflects the content of the passage, which discusses the historical evolution of bicycles. It is the best choice as it encapsulates the main theme and focus of the passage. Choice A: "Bicycles are better" is too vague and does not capture the specific content of the passage. Choice C: "Cycle your way to fitness" is misleading as the passage does not primarily focus on the fitness aspect of cycling. Choice D: "The popularity of bicycles" is not as precise as choice B in describing the passage, which primarily delves into the history rather than the popularity of bicycles.

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.
