1. According to the extract, which of the following statements most closely correlates with the definition of the term 'working man'?

• A. A working man is someone who is well versed in the workings of the soul.
• B. A working man is probably not involved in social activities due to the high physical demand of work.
• C. A working man is someone who earns wages in a traditional sense, often associated with the middle class.
• D. The working man historically transitions from the field to the factory and now to the screen.

Correct answer: C

Rationale: According to the extract, the term 'working man' refers to individuals who are actively employed and earn wages in a traditional sense. Charles Dickens emphasizes the importance of the working man having a share in the management of institutions designed for their benefit. This aligns with choice C, making it the correct answer. Choice A is incorrect as the extract does not mention anything about being well versed in the workings of the soul. Choice B is incorrect because the extract does not suggest that working men are not involved in social activities due to the physical demands of their work. Choice D is also incorrect as the extract does not focus on the historical transitions of the working man.

2. Which of the following is the primary physical barrier the body uses to prevent infection?

• A. mucus membranes
• B. stomach acid
• C. skin
• D. urine

Correct answer: C

Rationale: The correct answer is 'C: skin.' The skin is the primary physical barrier the body uses to prevent infection. It acts as a protective shield that prevents harmful microorganisms from entering the body. The outer layer of the skin, known as the epidermis, acts as a tough physical barrier that blocks the entry of pathogens. Additionally, the skin has special immune cells that can help fight off invaders that manage to breach the physical barrier. Choices A, B, and D are incorrect. While mucous membranes, stomach acid, and urine play important roles in the body's defense against pathogens, the primary physical barrier is the skin, which covers the entire body and provides a robust protective barrier.

3. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.

4. Which structure in the body is responsible for producing testosterone?

• A. Adrenal glands
• B. Pituitary gland
• C. Testes
• D. Pancreas

Correct answer: C

Rationale: The correct answer is C: Testes. The testes are responsible for producing testosterone, the hormone that plays a crucial role in male secondary sexual characteristics such as facial hair, deepening of the voice, and muscle development. The adrenal glands primarily produce cortisol and aldosterone, not testosterone. The pituitary gland regulates hormone production in various glands, including the testes, but it does not directly produce testosterone. The pancreas is responsible for producing insulin and glucagon to regulate blood sugar levels, not testosterone.

5. Which functional group is commonly found in ketones?

• A. Hydroxyl
• B. Carbonyl
• C. Ester
• D. Amine

Correct answer: B

Rationale: Ketones contain a carbonyl functional group, which consists of a carbon atom double-bonded to an oxygen atom. This distinguishes ketones from other functional groups such as hydroxyl, ester, and amine. The presence of the carbonyl group, not hydroxyl (choice A), ester (choice C), or amine (choice D), is characteristic of ketones, making choice B, 'Carbonyl', the correct answer.
