- B. Losing weight can decrease blood pressure.
- C. Older people must pay attention to their blood pressure.

Statements A, B, and D provide factual information supported by scientific evidence, making them statements of fact rather than opinion.

- A. Bone pain is a symptom of sickle-cell anemia.
- B. Sickle-cell anemia affects oxygen transport in the body.
- C. Sickle-cell anemia is a genetically inherited disease.
- D. Sickle-cell anemia is a painful, inherited disease.
Correct Answer: D
Rationale: The correct answer is D. The passage focuses on describing sickle-cell anemia as a painful and inherited disease. It details how the abnormal sickle-shaped cells cause symptoms like bone pain, fever, and fatigue. While bone pain is mentioned as a symptom, it is not the main idea of the passage. Choice A is incorrect. Choice B, which mentions oxygen transport, is not the main idea but a general concept. Choice C, stating genetically inherited diseases affect thousands, is too broad and does not focus on the specifics of sickle-cell anemia. Therefore, D is the most precise choice.

- A. Regulating the metabolism.
- B. Stimulating the immune system.
- C. Regulating leptin, an appetite-controlling hormone.
- D. Facilitating calcium retention.
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.
