HESI A2 Reading Comprehension V2 2024

Correct Answer: C

Rationale: The correct answer is C, to provide an overview of CF and how it is inherited. This is because the passage discusses cystic fibrosis (CF) in general, including its inheritance pattern. It does not focus solely on causes, transmission through families, or why some Americans have CF and others do not. By providing an overview and explaining inheritance, the passage serves the purpose of informing readers about CF comprehensively.

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: C

Rationale: The correct answer is C, to provide an overview of CF and how it is inherited. This is because the passage discusses cystic fibrosis (CF) in general, including its inheritance pattern. It does not focus solely on causes, transmission through families, or why some Americans have CF and others do not. By providing an overview and explaining inheritance, the passage serves the purpose of informing readers about CF comprehensively.

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.
