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. FRAX takes into account all of the following factors EXCEPT ___________.

• A. Lifestyle choices
• B. Exposure to toxins
• C. Genetic heritage
• D. Exposure to sunlight

Correct answer: B

Rationale: FRAX, a tool used to assess fracture risk, considers various factors like lifestyle choices, genetic heritage, and exposure to sunlight. However, exposure to toxins is not mentioned in the provided extract as a factor considered by FRAX. Therefore, the correct answer is B. Exposure to toxins is unrelated to fracture risk assessment as per the information provided. Lifestyle choices, genetic heritage, and exposure to sunlight are all factors that FRAX takes into consideration to determine the risk of experiencing a fracture within the next decade.

3. The author describes cosmetics in each of the following cultures EXCEPT ___________.

• A. Greek
• B. Egyptian
• C. Roman
• D. Native American

Correct answer: D

Rationale: The author provides descriptions of cosmetic practices in Greek, Egyptian, and Roman cultures but does not mention Native American practices regarding cosmetics. This absence of information about Native American culture leads to the conclusion that option D is correct since it reflects a lack of discussion on that specific culture.

4. In this passage, which of the following is not mentioned as a role of HGH in the human body?

• A. Regulating the metabolism.
• B. Stimulating the immune system.
• C. Regulating leptin, an appetite-controlling hormone.
• D. Facilitating calcium retention.

Correct answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

5. 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.
