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. 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.
3. What was the most dangerous part of building the Golden Gate Bridge?
- A. Balancing the road to prevent collapse.
- B. Constructing the towers due to their height.
- C. Suspending the cables with difficulty.
- D. Ensuring the critical balance of the bridge.
Correct answer: A
Rationale: The most dangerous part of building the Golden Gate Bridge, as mentioned in the passage, was keeping the road balanced to prevent it from collapsing. While constructing the towers and suspending the cables were challenging tasks, the passage specifically highlights the balancing of the bridge as the most treacherous aspect of the construction. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not reflect the primary danger emphasized in the passage.
4. What is implied by this paragraph?
- A. Overeating and alcohol abuse can lead to serious health issues.
- B. We should implement stricter laws to prevent alcohol abuse.
- C. Emotional eating is a major health concern.
- D. Consuming food and drinks in moderation is crucial.
Correct answer: A
Rationale: The paragraph implies that overeating and alcohol abuse can lead to serious physical and mental health problems. It highlights the strain on the heart, risk of diabetes, and shortened lifespan due to overeating. It also mentions the negative consequences of alcohol abuse, such as alcoholism, drunk driving leading to accidents, and spousal/child abuse. While emotional eating is mentioned, the main focus is on the health risks of overeating and alcohol abuse. Therefore, choice A is the correct answer as it captures the essence of the paragraph's message.
5. 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.
