1. What is the diameter of a loop if its radius is 6 meters?

• A. 6 m
• B. 12 m
• C. 18 m
• D. 36 m

Correct answer: B

Rationale: The diameter of a loop is calculated by multiplying the radius by 2. Since the radius is 6 meters, the diameter is 6 × 2 = 12 meters. Therefore, the correct answer is 12 meters. Choice A (6 m) is the radius, not the diameter. Choices C (18 m) and D (36 m) are incorrect as they do not reflect the correct calculation for determining the diameter of a loop.

2. Express 2/5 as a decimal.

• A. 0.2
• B. 0.25
• C. 0.4
• D. 2.5

Correct answer: C

Rationale: To express 2/5 as a decimal, you divide the numerator (2) by the denominator (5). 2 ÷ 5 = 0.4. Choice A (0.2) is the decimal equivalent of 1/5, not 2/5. Choice B (0.25) is the decimal equivalent of 1/4, not 2/5. Choice D (2.5) is not the correct decimal equivalent of 2/5 as it is greater than 1.

3. What does Milieu mean?

• A. A person's background
• B. The environmental condition or setting
• C. A person's history
• D. The chemical composition

Correct answer: B

Rationale: The correct answer is B: 'The environmental condition or setting.' Milieu refers to the surroundings or environment in which a person lives or operates. Choice A ('A person's background') is incorrect as it refers more to someone's personal history rather than the external environment. Choice C ('A person's history') is also incorrect as it specifically relates to an individual's past events and experiences. Choice D ('The chemical composition') is unrelated to the meaning of milieu, which pertains to the physical or social setting.

4. In an example of a male with hemophilia and a female carrier, what percentage of the offspring is predicted to be carriers only?

• A. 0%
• B. 25%
• C. 50%
• D. 100%

Correct answer: C

Rationale: In this scenario, the male offspring will inherit the X chromosome with the hemophilia gene from the mother, as males have one X chromosome inherited from their mother. The female offspring will inherit one normal X chromosome from the father and one X chromosome with the hemophilia gene from the mother, making them carriers of the hemophilia trait. Therefore, 50% of the offspring will be carriers only. Option A (0%) is incorrect as female offspring will inherit the X chromosome with the hemophilia gene from the mother. Option B (25%) is incorrect as the female offspring will not be unaffected. Option D (100%) is incorrect as not all offspring will be carriers, only the female offspring.

5. Which bones do the rotator cuff help to stabilize?

• A. Radius and humerus
• B. Scapula and clavicle
• C. Humerus and scapula
• D. Ulna and radius

Correct answer: C

Rationale: The correct answer is C: Humerus and scapula. The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint. Specifically, the rotator cuff muscles help to stabilize the head of the humerus (the upper arm bone) within the shallow socket of the scapula (shoulder blade). This stabilizing action is crucial for maintaining shoulder joint function and preventing injuries. Choices A, B, and D are incorrect because the rotator cuff primarily stabilizes the humerus and scapula, not the radius, ulna, or clavicle.
