Which statement would not be inferred by the reader in the passage about Barefoot Running?

Correct Answer: D

Rationale: The passage does not suggest that Olympic runners ran barefoot before 195o.

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: C

Rationale: The passage discusses the challenges and symptoms associated with sickle-cell anemia, portraying a somber and serious tone. The descriptions of persistent pain, difficulties, and the impact on individuals' lives make the overall tone fairly grim. The essay focuses on the hardships faced by individuals with sickle-cell anemia, highlighting the severity of the disease. Choices A, B, and D are incorrect because the tone of the essay is not informal, insensitive, or uplifting. It is important to consider the language used, the subject matter, and the overall emotional impact of the text to determine the tone accurately.

Correct Answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.
