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 title 'The Debate over Barefoot Running' captures the main discussion in the passage.

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.

Correct Answer: C

Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.

Correct Answer: C

Rationale: Tolerance in this context refers to endurance, particularly in relation to pain.

Correct Answer: D

Rationale: The passage never says whether or not the CDC succeeded in its original mission (choice A) or whether it continued to be led by doctors (choice B). Inferring either of those things would be a leap unsupported by the text. Choice C is countered by information in the final

Correct Answer: D

Rationale: The passage does not mention the divisions that make up the current CDC.

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.

Correct Answer: A

Rationale: This is an opinion that cannot be objectively verified.
