In this passage, which of the following is not mentioned as a role of HGH in the human body?

Correct Answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

Correct Answer: A

Rationale: Unprocessed in this context means natural and untreated, as it refers to whole foods.

Correct Answer: D

Rationale: The passage does not suggest that super foods are more expensive than processed foods.

Correct Answer: B

Rationale: Substitute the choices in place of the vocabulary word. Only reduced (choice B) fits the context.

Correct Answer: B

Rationale: The tone of the essay is confident, as the author argues for the positive effects of sunlight.

Correct Answer: B

Rationale: The main idea of the passage about High Fructose Corn Syrup is that it may be contributing to obesity in America. This is evident from the information provided in the extract, which discusses how HFCS has been linked to health issues, including obesity. Choice A is incorrect because the passage primarily focuses on the potential health risks associated with HFCS consumption, not just the examination by the American Medical Association. Choice C is irrelevant as it only talks about the manufacturing process of HFCS, which is not the central theme of the passage. Choice D is incorrect as it emphasizes the preference of rats for HFCS, which is a minor point compared to the potential impact on human health, particularly in relation to obesity.

Correct Answer: C

Rationale: This is an opinion because it is a subjective statement about taste.

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: In this context, touted means glorified, as it refers to the promotion of aromatherapy.
