1. Which of the following materials has the lowest density?

• A. Water
• B. Cork
• C. Aluminum
• D. Steel

Correct answer: B

Rationale: Cork has the lowest density among the given options. Cork is a lightweight material derived from the bark of cork oak trees and is known for its low density, making it float on water. Water, aluminum, and steel have higher densities compared to cork. Water is denser than cork because it has a consistent density of 1 g/cm³. Aluminum and steel are metals with much higher densities due to their atomic structures, making them denser than cork.

2. What is the primary function of the liver?

• A. Detoxifying harmful substances
• B. Producing bile
• C. Producing insulin
• D. Storing glycogen

Correct answer: A

Rationale: The primary function of the liver is to detoxify harmful substances in the blood. While the liver also produces bile, which aids in digestion, stores glycogen for energy storage, and participates in metabolism, its main and essential function is detoxification. Producing insulin is mainly attributed to the pancreas, not the liver.

3. What is the main function of the endocrine system?

• A. To fight infections
• B. To regulate body functions through hormones
• C. To produce red blood cells
• D. To transport oxygen

Correct answer: B

Rationale: The main function of the endocrine system is to regulate various body functions by releasing hormones, which act as chemical messengers. These hormones help maintain homeostasis, regulate metabolism, growth, development, and other essential functions in the body. Option A is incorrect as fighting infections is primarily the role of the immune system, not the endocrine system. Option C is incorrect as the production of red blood cells mainly occurs in the bone marrow. Option D is incorrect as the transportation of oxygen is primarily carried out by the respiratory and circulatory systems. Therefore, option B is the correct answer as it accurately describes the primary role of the endocrine system.

4. What does the term 'counterfeit' mean?

• A. Real
• B. Fake
• C. Accurate
• D. Honest

Correct answer: B

Rationale: The correct answer is B: 'Fake.' Counterfeit refers to something that is not genuine or a copy made to deceive. Choice A, 'Real,' is incorrect because counterfeit items are not real. Choice C, 'Accurate,' is incorrect as counterfeit implies inaccuracy. Choice D, 'Honest,' is incorrect as counterfeit items are deceptive and not honest.

5. If illegal operators are posing as licensed pharmacists, what are they doing?

• A. Modeling
• B. Inquiring
• C. Positioning
• D. Pretending

Correct answer: D

Rationale: If illegal operators are posing as licensed pharmacists, they are pretending to be licensed pharmacists when they are not. This deceptive behavior is misleading and potentially dangerous for consumers seeking legitimate medical advice and products. Choice A, modeling, implies imitating behavior or appearance, which is not the case here. Choice B, inquiring, suggests seeking information or asking questions, which is not the correct behavior in this context. Choice C, positioning, refers to arranging or placing things in a particular way, which is not relevant to the situation described in the question.
