1. Which word is not spelled correctly in the sentence: 'The physician thought it was unnecessary to explain the procedure.'

• A. physician
• B. unnecessary
• C. explain
• D. procedure

Correct answer: B

Rationale: The word 'unnecessary' is misspelled as 'unecessary' in the sentence. The correct spelling should have double 'n' as in 'unnecessary'. Choice A, C, and D are spelled correctly in the sentence provided.

2. How many pounds are in 48 ounces?

• A. 3 lbs
• B. 6 lbs
• C. 4 lbs
• D. 8 lbs

Correct answer: A

Rationale: To convert ounces to pounds, you need to know that there are 16 ounces in a pound. Therefore, to find out how many pounds are in 48 ounces, you divide 48 by 16: 48 ÷ 16 = 3 pounds. This means that 48 ounces is equivalent to 3 pounds. Choice B, 6 lbs, is incorrect as it doesn't correctly convert 48 ounces to pounds. Choice C, 4 lbs, is incorrect as it doesn't take into account the conversion factor of 16 ounces per pound. Choice D, 8 lbs, is also incorrect as it doesn't reflect the accurate conversion of ounces to pounds.

3. 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.

4. Which brain structure is responsible for regulating hunger and thirst?

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

Correct answer: A

Rationale: The correct answer is the hypothalamus. This brain structure plays a crucial role in regulating hunger, thirst, body temperature, and various autonomic functions. The hypothalamus is responsible for maintaining homeostasis by responding to sensory signals and releasing appropriate hormones to control these essential physiological processes. The cerebellum (Choice B) is primarily involved in coordinating movement and balance, not hunger and thirst. The medulla oblongata (Choice C) is responsible for regulating vital autonomic functions such as breathing and heartbeat, but not hunger and thirst. The cerebrum (Choice D) is involved in higher brain functions such as thinking, decision-making, and processing sensory information, but it is not primarily responsible for regulating hunger and thirst.

5. Convert 1/5 to a decimal.

• A. 0.5
• B. 0.2
• C. 1.5
• D. 0.15

Correct answer: B

Rationale: To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 1 ÷ 5 = 0.2. Therefore, the correct answer is B. Choice A (0.5) is incorrect because the decimal form of 1/5 is not 0.5. Choice C (1.5) is incorrect as it is the sum of 1 and 0.5, not the decimal form of 1/5. Choice D (0.15) is incorrect as it is the decimal form of 15/100, not 1/5.
