What is the author's primary purpose in writing the essay about Sunny-Side Up?

Correct Answer: D

Rationale: The author's purpose is to inform readers about the benefits of sunlight.

Rationale: The tone is uncertain because the author raises questions about the efficacy of aromatherapy.

Correct Answer: B

Rationale: The main idea of the passage about High Fructose Corn Syrup is that it may be contributing to obesity in America. This is evident from the information provided in the extract, which discusses how HFCS has been linked to health issues, including obesity. Choice A is incorrect because the passage primarily focuses on the potential health risks associated with HFCS consumption, not just the examination by the American Medical Association. Choice C is irrelevant as it only talks about the manufacturing process of HFCS, which is not the central theme of the passage. Choice D is incorrect as it emphasizes the preference of rats for HFCS, which is a minor point compared to the potential impact on human health, particularly in relation to obesity.

Correct Answer: A

Rationale: The main idea is that super foods are low in calories but provide essential nutrients with significant health benefits.

Correct Answer: C

Rationale: A statement of fact can be proved or checked. A statement of opinion is what someone thinks or believes. In this case, statements A, B, and D could be proved scientifically, but statement C is simply a suggestion. While it is advisable for older people to monitor their blood pressure due to the increased risk associated with aging, the statement itself is an opinion because it suggests what older people 'must' do, which is a subjective viewpoint rather than a verifiable fact. Statements A, B, and D provide factual information supported by scientific evidence, making them statements of fact rather than opinion.

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: B

Rationale: Compelling in this context means convincing, as it relates to the argument presented.

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: B

Rationale: The correct answer is B. The passage clearly states that there are treatments for hypertension, so the statement that there is presently no reliable treatment for hypertension cannot be inferred from the text. Choice A can be inferred from paragraph 3 where it mentions losing weight to decrease blood pressure. Choice C can be inferred from paragraph 1 where it states that African Americans are more likely to have hypertension. Choice D can be inferred from paragraph 2 where it explains that older people are most often diagnosed with hypertension due to changes in blood vessels as they age.
