What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?

A. A state of tiredness.

B. A state of being satisfied.

C. A state of being overloaded.

D. A state of confusion.

Correct Answer: B
Rationale: Satiety refers to a state of being satisfied, particularly in terms of appetite. In the context of the excerpt provided, it explains that individuals who lack adequate sleep may experience lowered levels of leptin, a hormone that controls appetite. As a result, even after meeting their caloric needs, they may still crave carbohydrates, indicating a lack of satisfaction or satiety. This can lead to obesity and disrupt healthy eating habits. Therefore, choice B, 'A state of being satisfied,' is the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the meaning of satiety in the context of appetite regulation and sleep's impact on food cravings.

• A. To inform readers about Thailand's historical customs.
• B. To entertain readers with the origins of the term 'white elephant.'
• C. To explain the tradition of giving white elephants.
• D. To criticize the tradition of giving white elephants as gifts.

Correct Answer: C
Rationale: The correct answer is C: 'To explain the tradition of giving white elephants.' The passage provides historical context about the practice of giving white elephants as gifts in ancient Siam, now Thailand. It explains how white elephants were considered sacred, could not be put to work, and became a burden to the recipients. The author's purpose is to shed light on this tradition and its implications, not to inform readers about Thailand in general (choice A), entertain with fun facts (choice B), or criticize the tradition (choice D). Choices A and B are incorrect because the passage focuses specifically on the tradition of giving white elephants, not on broader aspects of Thailand or entertainment. Choice D is incorrect because the passage does not criticize the tradition but rather provides a factual account of its historical significance.

• A. Dishonor
• B. Go without
• C. Connect to
