1. Why did Macmillan add iron rims to the tires of his bicycle?

• A. Increase the weight of the bicycle.
• B. Enhance the durability of the tires.
• C. Reduce the bumpiness of the ride.
• D. Decrease the level of fatigue during the ride.

Correct answer: B

Rationale: Macmillan added iron rims to his bicycle tires to enhance their durability and make them last longer. This innovation aimed to prevent the tires from getting worn down quickly. Adding weight to the bicycle (Choice A) was not the purpose of adding iron rims. While adding iron rims could potentially reduce the bumpiness of the ride (Choice C) by providing more stability, the main objective was to improve tire longevity. Similarly, reducing the level of fatigue during the ride (Choice D) was not the primary reason for adding iron rims.

2. Which sound waves have a lower 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: B

Rationale: Sound waves that are farther apart have a lower pitch. The Doppler Effect explains that as objects emitting sound move away, the sound waves become more spaced out, resulting in a lower frequency and a lower pitch. Choice A is incorrect because waves that are closer together have a higher frequency and a higher pitch. Choices C and D are not directly related to determining the pitch of sound waves.

3. Which is the best title for this passage?

• A. “Medical Treatment for Gout”
• B. “Uric Acid Affects the Joints”

• A. Bicycles have been evolving for centuries.
• B. Bicycles have evolved significantly over time.
• C. Bicycles have remained unchanged since their invention.
• D. Bicycles are no longer a popular means of transportation.

Correct answer: B

Rationale: The correct conclusion that can be drawn from the passage is that bicycles have evolved significantly over time. The passage discusses the evolution of bicycles from their early wooden, pedal-less designs to the modern safety bicycle with equal-sized wheels and chain-driven pedals. Each inventor mentioned in the passage contributed to significant improvements in bicycle design, making them more efficient and popular for transportation and recreation. Choice A is incorrect because the passage does not mention bicycles evolving continuously for centuries, but rather highlights specific innovations over time. Choice C is incorrect as the passage clearly describes the various improvements and changes made to bicycles since their invention. Choice D is also incorrect as the passage emphasizes the continued popularity and usefulness of bicycles for transportation all over the world.
