1. 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.

2. Which statement could be inferred from the passage?

• A. The Georgia lab had conducted a previous study on the connection between exercise and energy.
• B. Exercise regimes are not recommended for patients with serious health problems.
• C. An increase in energy levels does not always correspond directly to a reduction in fatigue.
• D. There were fewer than 10 participants in each group in the Georgia study.

Correct answer: A

Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before. Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions. Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue. Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

3. What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

• A. Dispersed.
• B. Incensed.
• C. Painstaking.
• D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

4. What is the meaning of the word 'sterile' as it is used in the second paragraph?

• A. free of bacteria
• B. healthy
• C. delicious
• D. impotent

Correct answer: A

Rationale: In the context provided, 'sterile' means free of bacteria. The text mentions that raw foods are not sterile and can be a common source of foodborne illnesses due to contamination with harmful bacteria. 'Healthy' (choice B) is incorrect as the term 'sterile' specifically refers to the absence of bacteria, not overall health. 'Delicious' (choice C) is irrelevant to the context of bacteria contamination. 'Impotent' (choice D) is also incorrect as it does not relate to the concept of being free from bacteria.

5. 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.
