1. Which structure in the skin is responsible for producing oil that keeps the skin and hair moisturized?

• A. Sudoriferous gland
• B. Sebaceous gland
• C. Hair follicle
• D. Melanocyte

Correct answer: B

Rationale: The correct answer is B: Sebaceous gland. Sebaceous glands are responsible for producing oil (sebum) that keeps the skin and hair moisturized. Sudoriferous glands produce sweat, not oil, and are involved in temperature regulation. Hair follicles are responsible for hair growth and do not produce oil directly. Melanocytes are cells responsible for producing melanin, the pigment that gives skin its color, and are not involved in oil production.

2. The patella, commonly known as the kneecap, is an example of a:

• A. Sesamoid bone
• B. Long bone
• C. Short bone
• D. Irregular bone

Correct answer: A

Rationale: The patella, also known as the kneecap, is an example of a sesamoid bone. Sesamoid bones develop within tendons, such as the patellar tendon in this case. The patella is embedded in the tendon of the quadriceps muscle, enhancing the mechanical advantage of the muscle and protecting the knee joint. Long bones, like the femur, are characterized by their elongated shape with growth plates at the ends. Short bones, such as those in the wrist and ankle, are cube-shaped bones. Irregular bones, like vertebrae, do not fit into the other bone shape categories due to their unique shapes and functions.

3. What is an actuary?

• A. A doctor who works in a hospital.
• B. The same as a hospitalist.
• C. An insurance agent who works in a hospital.
• D. A person who assesses insurance risks and premiums.

Correct answer: D

Rationale: An actuary is a person who assesses insurance risks and premiums. This is the primary role of an actuary, involving the analysis of financial consequences of risk. Choice A is incorrect as actuaries are not medical professionals. Choice B is incorrect as a hospitalist is a physician who works in a hospital, not related to actuarial work. Choice C is incorrect as actuaries are not insurance agents; they focus on risk assessment and not sales.

4. What is 0.5 liter in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: To convert liters to milliliters, you multiply the number of liters by 1000. Therefore, 0.5 liters equals 500 milliliters. This conversion is standard in various fields, making choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters.

5. They were able to reach the deck fastest to get a seat on a lifeboat. Which of the following sentences is written correctly and provides a clear explanation?

• A. Because the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
• B. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.
• C. Because of this, the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
• D. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.

Correct answer: B

Rationale: Option B provides a clear and grammatically correct explanation for why the majority of survivors came from first class - they were able to reach the deck fastest to get a seat on a lifeboat. The phrase 'Because of this' properly introduces the reason that follows. In Option A, a comma after 'Because' is unnecessary and disrupts the flow of the sentence. In Option C, 'Because this' is incomplete and lacks proper connection to the subsequent clause. Option D, similar to Option C, lacks clarity due to the absence of a full linking phrase. Therefore, Option B is the best choice as it conveys the explanation effectively and without grammatical errors.
