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

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. What is the best summary of this passage?

Correct answer: B

Rationale: The correct answer is B because it provides a comprehensive summary of the passage, explaining how the cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys. Choice A is incorrect as it only focuses on the heart and kidneys without mentioning the broader cardiovascular system. Choice C is incorrect as it solely emphasizes the role of baroreceptors in regulating blood pressure. Choice D is incorrect as it oversimplifies the role of chemoreceptors in monitoring oxygen levels without mentioning their impact on blood pressure regulation.

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

Correct answer: A

Rationale: In this context, 'respite' refers to relief, providing caregivers with temporary rest or a break from their caregiving duties. The word 'respite' is associated with giving caregivers a brief period of relief, not with treatment, guardianship, or specialization. The extract mentions 'respite services' along with caregiver services, indicating that respite is a form of support or relief for caregivers.

4. Which statement is not a detail from the passage?

Correct answer: C

Rationale: Choice C, 'The water cycle does not involve precipitation,' is not a detail from the passage. The passage clearly states that precipitation, such as rain, snow, sleet, or hail, is a crucial part of the water cycle. On the other hand, choices A, B, and D are all supported by the passage. Condensation occurs when water vapor cools, evaporation occurs when water changes into gas, and water evaporates from oceans and rivers are all mentioned in the text.

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

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.
