1. Athletes are often concerned with the question of what they need in their diets to increase muscle mass and strength. What biologic molecule would you recommend that would accomplish this?

• A. carbohydrates
• B. proteins
• C. lipids
• D. nucleic acids

Correct answer: B

Rationale: Proteins are essential for building and repairing muscle tissue. They contain amino acids, which are the building blocks of muscles. Athletes looking to increase muscle mass and strength should focus on consuming adequate amounts of high-quality proteins in their diets. Carbohydrates provide energy for workouts, lipids are important for overall health but do not directly contribute to muscle building, and nucleic acids are involved in genetic activities rather than muscle growth.

2. What conclusion can you draw from the first sentence of the passage?

• A. Osteoporosis is more common than anyone previously imagined.
• B. The media give a lot of overall coverage to osteoporosis.
• C. Only women are at high risk for developing bone thinning.
• D. Thinning bones is not considered a serious medical problem.

Correct answer: B

Rationale: The correct answer is B. The first sentence suggests that osteoporosis receives significant media coverage, indicating that the media gives a lot of overall coverage to the issue. This conclusion can be drawn as the passage mentions how osteoporosis is a major health concern for women and is widely covered in newspapers and television commercials. Choice A is incorrect because the passage does not mention the prevalence of osteoporosis compared to previous estimates. Choice C is incorrect as the passage highlights that men are being overlooked in terms of bone thinning concerns. Choice D is incorrect as the passage emphasizes the seriousness of bone thinning and the need for preventive measures.

3. What is the best description for the word operated in this sentence? Rural communities are increasingly taking ownership of their hospitals, which may be operated by administrative medical groups.

• A. Performing surgery
• B. In effect
• C. Managed and run
• D. Brought about

Correct answer: C

Rationale: In the context of the sentence provided, the word 'operated' is best described as 'managed and run.' This choice accurately reflects the idea that rural communities are taking ownership and control of their hospitals, which may be overseen and operated by administrative medical groups. The word 'operated' here implies the day-to-day management and functioning of the hospitals, making option C the most suitable description in this context. Choices A, B, and D are incorrect as they do not capture the essence of 'operated' in the context of managing and running the hospitals.

4. Which of these percentages equals 1.25?

• A. 1250%
• B. 25%
• C. 50%
• D. 125%

Correct answer: D

Rationale: To convert 1.25 to a percentage, multiply by 100. Therefore, 1.25 equals 125%. The correct answer is D because 125% is the percentage that represents 1.25. Choices A, B, and C are incorrect. A (1250%) is 10 times greater than the correct answer, B (25%) is 100 times smaller, and C (50%) is 2 times smaller than the correct percentage equivalent of 1.25.

5. Which part of the brain is responsible for balance and coordination?

• A. Cerebellum
• B. Cerebrum
• C. Medulla oblongata
• D. Hypothalamus

Correct answer: A

Rationale: The correct answer is the cerebellum. The cerebellum, situated at the back of the brain, is responsible for coordinating voluntary movements and maintaining balance and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate motor movements. The cerebrum (choice B) is responsible for higher brain functions such as thinking and decision-making, the medulla oblongata (choice C) controls vital autonomic functions like breathing and heart rate, and the hypothalamus (choice D) is involved in regulating basic biological needs like hunger, thirst, and body temperature.
