1. What does the term elasticity mean, as used in the passage about Hypertension?

A. Firmness.
B. Compactness.
C. Flexibility.
D. Rigidity.

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.

2. What does the word 'integral' mean as used in the first paragraph of the passage?

A. Central
B. Initial
C. Trifling
D. Irrelevant

Correct answer: A

Rationale: In this context, 'integral' means 'central' or essential. The passage discusses the debate around spanking as a method of discipline. Some parents consider it an integral part of teaching right and wrong, highlighting its central importance. Therefore, the correct answer is 'A: Central.' Choice B, 'Initial,' is incorrect as the word 'integral' does not refer to something being at the beginning of a process or sequence. Choice C, 'Trifling,' is incorrect as 'integral' implies significance and importance, opposite to being trivial. Choice D, 'Irrelevant,' is incorrect as the passage clearly states that some parents view spanking as essential, making it relevant and not irrelevant.

3. What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?

A. A state of tiredness.
B. A state of being satisfied.
C. A state of being overloaded.
D. A state of confusion.

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.

4. What is the main idea of the passage about Toxins and Your Health?

A. Environmental toxins may have dire health effects over time.
B. Of three toxins studied, lead has the worst effect on health.
C. Toxins may accumulate in the bones of older patients.
D. Johns Hopkins University has discovered a new use for lead.

Correct answer: A

Rationale: The passage emphasizes the long-term effects of environmental toxins such as lead, pesticides, and mercury on brain health, particularly as individuals age. Dr. Brian Schwartz's quote highlights the link between environmental exposure and cognitive decline, framing the entire discussion around the potential health ramifications of such exposure over time. This clearly aligns with choice A, making it the main idea of the passage.

5. Which is not listed as an example of a low-impact sport?

A. Martial arts
B. Basketball
C. Yoga
D. Weight lifting

Correct answer: B

Rationale: Basketball is not listed as a low-impact sport in the extract provided; the others (martial arts, yoga, and weight lifting) are considered low-impact activities. The extract mentions that students can participate in low-impact sports like yoga, martial arts, and weight lifting in modern PE classes, emphasizing their benefits and the focus on general skills. Basketball, on the other hand, is not included in the list of low-impact sports mentioned in the extract, making it the correct answer. This demonstrates the importance of understanding the difference between high-impact and low-impact sports for maintaining fitness and health.
