1. What does the passage about the Water Cycle explain?

• A. The water cycle consists of precipitation, evaporation, and condensation.
• B. The water cycle is a continuous process of recycling water on Earth.
• C. Rain is the most important part of the water cycle.
• D. Evaporation is the final step in the water cycle.

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, starting with precipitation (rain, snow, sleet, or hail) falling to the ground, followed by runoff, evaporation transforming liquid water into water vapor, and finally condensation turning water vapor back into liquid. Choice B is incorrect because it is too broad and doesn't specifically address the stages of the water cycle. Choice C is incorrect as rain is just one part of the water cycle and not the most important. Choice D is incorrect as evaporation is not the final step but one of the stages of the water cycle.

2. Why is an unwanted gift called a white elephant?

• A. It is a good gift to give at the party
• B. Gifts are never unwanted
• C. Siam's rulers punished with the gift
• D. It is rare to get an unwanted gift

Correct answer: C

Rationale: The term 'white elephant' originated from the practice of the kings of Siam (now Thailand) giving rare and sacred white elephants as gifts. These white elephants were highly prestigious but also very expensive to maintain, causing financial burdens on the recipients. The kings of Siam used white elephants as a punishment for those who displeased them. The recipients were required to care for the white elephant in a grand style, resulting in financial liabilities that could make them impoverished. Over time, the term 'white elephant' evolved to describe any valuable item that is burdensome or unwanted. Therefore, choice C is correct. Choices A, B, and D are incorrect because they do not accurately explain the origin and meaning of the term 'white elephant' in the context of unwanted gifts.

3. What is the meaning of the word disparate as used in the first paragraph?

• A. Unusual
• B. Diverse
• C. Trivial
• D. Damaging

Correct answer: B

Rationale: "Disparate" means diverse or different. The passage discusses how Lyme disease has various symptoms that mimic other diseases, making it difficult to diagnose.

4. 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.

5. What does Macmillan's invention of the bicycle signify?

• A. He made important changes in bicycle design.
• B. He invented the first bicycle with pedals.
• C. He developed the modern chain drive.
• D. He improved the safety of bicycles.

Correct answer: B

Rationale: Macmillan's invention of pedals was a significant milestone in bicycle history as it allowed for quicker and more efficient travel. The provided extract mentions that Macmillan's bicycle had foot-operated cranks like pedals, which enabled the rider to travel at a quick pace. This innovation marked a crucial development in the evolution of bicycles. While choices A, C, and D are related to advancements in bicycle design and safety, the key significance of Macmillan's invention lies in introducing pedals to bicycles, making choice B the correct answer.
