1. What is the main idea of the passage about The Sleep Workout?

Correct answer: C

Rationale: The main idea of the passage is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The passage emphasizes how muscle growth occurs during rest periods following a workout, with sleep being a critical time for muscle fiber rebuilding. The connection between sleep, human growth hormone (HGH) release, and muscle development is highlighted. Choice A is incorrect because while the passage mentions the link between inadequate sleep and obesity due to altered appetite hormones, the main focus is on muscle development. Choice B is incorrect because although the passage discusses HGH release during deep sleep, the primary emphasis is on the role of uninterrupted sleep in muscle development. Choice D is incorrect because while the passage acknowledges that developing muscle growth is essential for health as we age, the key point is the significance of uninterrupted sleep in the muscle development process.

Correct answer: B

Rationale: In this context, "watchdog" refers to a guard or overseer, specifically relating to Lifewings Partners’ mission of ensuring safety and preventing medical errors. The organization acts as a monitor in healthcare settings, which aligns with the definition of a watchdog, confirming that option B is correct.

3. Choose the best summary of the passage about microbes.

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.

4. What fact is stated about the Amazon Rainforest in the passage?

The passage describes the rainforest as home to over 2,000 birds and mammals, with one in every five birds in the world living there. It also mentions the vast variety of insects, trees, and plants present in the rainforest, showcasing its rich ecosystem. Choice A is incorrect as the passage does not directly state that the Amazon Rainforest is shrinking rapidly, although it does mention the dangers it faces. Choice C is incorrect as the passage clearly indicates that human activity, such as deforestation, poses a significant threat to the rainforest. Choice D is incorrect as the passage provides evidence of a high number of animals inhabiting the Amazon Rainforest.

5. What is the meaning of the word impoverished in the first paragraph?

Correct answer: D

Rationale: The word 'impoverished' typically refers to a state of extreme poverty or being financially ruined. In the context of the first paragraph, where it is used to describe the condition of a certain group of people, it indicates that they are lacking in financial resources or are in a state of deprivation. Choice A 'Honored' is incorrect as it has a positive connotation opposite to the negative meaning of 'impoverished.' Choice B 'Nobility' is incorrect as it refers to a high social rank or class, which is unrelated to the financial state implied by 'impoverished.' Choice C 'Rich' is incorrect as it is the opposite of 'impoverished,' denoting wealth and abundance, not financial weakness.
