1. Which sound waves have a higher pitch?

• A. Those waves that are closer together
• B. Those waves that are farther apart
• C. Those waves that travel a long distance
• D. Those waves that travel a short distance

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.

2. What is the meaning of the word moderation as used in the second paragraph?

• A. Adequate amounts
• B. Intervals of time
• C. Excess
• D. Variation

Correct answer: A

Rationale: In this context, moderation means consuming adequate amounts of unsaturated fats. The passage highlights that unsaturated fats like olive oil and omega-3 fatty acids are beneficial when consumed in appropriate quantities. Choice B, intervals of time, is incorrect as it does not relate to the consumption of fats. Choice C, excess, is incorrect because moderation implies avoiding excess consumption. Choice D, variation, is unrelated to the context of consuming fats in appropriate amounts.

3. 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.

4. What is the meaning of the word leached as used in the last paragraph?

• A. Sucked
• B. Compressed
• C. Seeped
• D. Materialized

Correct answer: C

Rationale: "Leached" refers to the process by which substances, such as lead, seep or dissolve out of materials, in this case, water pipes.

5. What is the main idea of the passage about The Sleep Workout?

• A. Insufficient sleep can lead to obesity.
• B. Insufficient sleep inhibits the natural release of human growth hormone in the human body.
• C. Getting the proper amount of uninterrupted sleep plays a major role in the development of muscle.
• D. Developing muscle growth is an effective way to stay healthy as we get older.

Correct answer: C

Rationale: The main idea of the passage is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The passage emphasizes how muscle growth occurs during rest periods following a workout, with sleep being a critical time for muscle fiber rebuilding. The connection between sleep, human growth hormone (HGH) release, and muscle development is highlighted. Choice A is incorrect because while the passage mentions the link between inadequate sleep and obesity due to altered appetite hormones, the main focus is on muscle development. Choice B is incorrect because although the passage discusses HGH release during deep sleep, the primary emphasis is on the role of uninterrupted sleep in muscle development. Choice D is incorrect because while the passage acknowledges that developing muscle growth is essential for health as we age, the key point is the significance of uninterrupted sleep in the muscle development process.
