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.

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.

Rationale: The passage suggests that more studies are needed to determine the true benefits of aromatherapy.

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.
