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

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.

Correct Answer: C

Rationale: The summary accurately reflects the balanced view of the benefits and risks of sunlight.

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.

Correct Answer: B

Rationale: Compelling in this context means convincing, as it relates to the argument presented.

Correct Answer: D

Rationale: The author does not conclude choice A, and the passage does not deal with choice B. Only one paragraph deals with the topic in choice C. The passage is mostly about the pros and cons of barefoot running, making D the best choice

Correct Answer: D

Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.

Correct Answer: A

Rationale: The passage discusses the positive effects of sunlight, including vitamin D synthesis.

Correct Answer: D

Rationale: The author's purpose is to inform readers about the benefits of sunlight.

Correct Answer: D

Rationale: The title 'The Debate over Barefoot Running' captures the main discussion in the passage.
