Correct Answer: B

Rationale: The best summary of the passage is choice B. The passage discusses concerns about the impact of high fructose corn syrup (HFCS) on health, particularly its link to obesity. It mentions a recent study on rats that confirms suspicions about HFCS contributing to unhealthful weight gains. Choices A, C, and D are incorrect as they introduce recommendations or implications not explicitly mentioned in the passage. Choice A goes beyond the information by stating that scientists recommend removing HFCS from grocery products, choice C suggests that using HFCS is preferable until more research is done, and choice D implies immediate healthful results on overweight patients by avoiding HFCS, as suggested by the AMA, which is not supported by the passage.

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.
