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 does the term elasticity mean, as used in the passage about Hypertension?
- A. Firmness.
- B. Compactness.
- C. Flexibility.
- D. Rigidity.
Correct Answer: C
Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.
