1. What is the meaning of the word 'shifts' as used in the third paragraph?

• A. Alterations
• B. Stints
• C. Removals
• D. Transfers

Correct answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

2. What is the relationship between the tilt of the Earth and seasons as explained in the passage on Daylight Savings Time?

• A. The tilt of the Earth has no effect on seasons.
• B. The tilt of the Earth creates seasons.
• C. The tilt of the Earth changes throughout the year.
• D. The tilt of the Earth is random and unpredictable.

Correct answer: B

Rationale: The correct answer is B: 'The tilt of the Earth creates seasons.' The passage explains that the tilt of the Earth causes the different seasons by changing the amount of sunlight different regions receive. This tilt results in varying angles at which sunlight reaches different parts of the Earth, leading to the seasonal changes in temperature and daylight hours. Choice A is incorrect because the passage clearly states that the tilt of the Earth does have an effect on the seasons. Choice C is incorrect because the tilt of the Earth remains relatively constant throughout the year. Choice D is incorrect as the tilt of the Earth is not random but follows a consistent pattern.

3. 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.

4. What does the word 'composed' mean in the passage on the Water Cycle?

• A. To consist of.
• B. To create.
• C. To separate.
• D. To destroy.

Correct answer: A

Rationale: In the context of the Water Cycle, 'composed' means 'to consist of' parts. For instance, water is composed of hydrogen and oxygen atoms. Therefore, the correct meaning of 'composed' in this context is to consist of various components. Choice B, 'To create,' is incorrect as 'composed' refers to the makeup of something rather than the act of making or creating. Choices C and D, 'To separate' and 'To destroy,' are also incorrect as they do not align with the meaning of 'composed' in the passage.

5. Why did Strauss set up a net during the construction of the Golden Gate Bridge?

• A. For suspension
• B. For balance
• C. For aesthetics
• D. For safety

Correct answer: D

Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.
