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: 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: D

Rationale: The correct answer is D because the passage does not mention anything about vitamin and mineral deficiencies in relation to sickle-cell anemia. Choice A is incorrect as the passage specifies that sickle-cell anemia is more common among people of South American or African descent. Choice B is correct as the passage states that symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain. Choice C is correct as the passage describes that the red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes. The passage does not discuss any relationship between vitamin and mineral deficiencies and sickle-cell anemia, making choice D the correct option.
