1. What is the meaning of the word 'evolved' in the first paragraph?

A. To spread
B. To gradually develop
C. To revolve
D. To shift

Correct answer: B

Rationale: In the context of the given extract, 'evolved' means to gradually develop. The systems in the body have evolved over time, indicating a gradual development and adaptation. 'To spread,' 'to revolve,' and 'to shift' do not capture the idea of a gradual development as portrayed in the text, making them incorrect choices.

2. What is the meaning of the word 'elasticity' in the last paragraph?

A. Something that is able to resist and be flexible
B. Something that is like plastic
C. Something that is dynamic and electrifying
D. Something that is silly

Correct answer: A

Rationale: 'Elasticity' refers to the ability of the arterial walls to resist and be flexible, which affects blood pressure. In the provided extract, it is mentioned that an increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. This demonstrates that elasticity refers to the property of being able to resist and be flexible, supporting choice A as the correct answer. The other choices, B, C, and D, do not accurately reflect the concept of elasticity in the context of arterial walls and blood pressure.

3. Which of the following statements is an opinion related to Hypertension?

A. Obese people are at risk for hypertension.
B. Losing weight can decrease blood pressure.
C. Older people must pay attention to their blood pressure.
D. Blurred vision or dizziness may be a sign of hypertension.

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.

4. Which is not mentioned as a possible result of being spanked in childhood?

A. Aggression
B. Coercive sex
C. Delinquency
D. Incontinence

Correct answer: D

Rationale: The correct answer is D: 'Incontinence.' The passage discusses the negative consequences of spanking in childhood, such as increased aggression, delinquent behavior, and future sexual problems like coercive sex. However, incontinence is not mentioned as a possible result of being spanked. Therefore, it is the correct choice. Choices A, B, and C are all supported by the passage, making them incorrect answers.
