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

• A. Insufficient sleep can lead to obesity.
• B. Insufficient sleep inhibits the natural release of human growth hormone in the human body.
• C. Getting the proper amount of uninterrupted sleep plays a major role in the development of muscle.
• D. Developing muscle growth is an effective way to stay healthy as we get older.

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.

What is the meaning of the word 'deceptive' as it is used in the fifth paragraph?

• A. misleading
• B. malicious
• C. illegal
• D. irritating

Correct Answer: A
Rationale: In the context provided, 'deceptive' means misleading. The passage discusses how the Federal Trade Commission (FTC) regulates product advertising to ensure that all information is truthful and not misleading. Therefore, the correct answer is 'A: misleading.' Choice B, 'malicious,' is incorrect as it implies harmful intent, which is not necessarily conveyed by the term 'deceptive' in this context. Choice C, 'illegal,' is incorrect because 'deceptive' does not solely refer to something being against the law, but rather to misleading information. Choice D, 'irritating,' is also incorrect as it does not capture the essence of 'deceptive' as used in the passage.
