2. What is the main concern the author raises about AI?

• A. Its limitations in achieving true intelligence and emulating human consciousness.
• B. Its potential for misuse in warfare and autonomous weapons systems.
• C. Its detrimental impact on the environment and resource consumption.

Rationale: The passage explicitly mentions concerns about bias, privacy, and job displacement, making D the main concern highlighted.

3. Which vitamin is essential for collagen production, a key component of connective tissues?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: B

Rationale: The correct answer is B: Vitamin C. Vitamin C is essential for collagen production, which is a key component of connective tissues. Collagen is a protein that provides structure and strength to various tissues in the body, including skin, bones, and tendons. Vitamin C plays a crucial role in the synthesis of collagen by acting as a cofactor for enzymes involved in collagen formation. Deficiency in Vitamin C can lead to impaired collagen production, resulting in weakened connective tissues and potential health issues like scurvy. While Vitamin A, D, and E are important for various bodily functions, Vitamin C specifically stands out for its vital role in collagen synthesis.

4. Percent Increase/Decrease: A medication dosage is increased by 20%. If the original dosage was 100mg, what is the new dosage?

• A. 80mg
• B. 100mg
• C. 120mg
• D. 140mg

Correct answer: C

Rationale: Multiply the original dosage (100mg) by 1 + the percentage increase (20% = 0.2) to get 120mg.

5. Which of the following is NOT a function of the cilia lining the respiratory tract?

• A. Trapping inhaled dust and debris
• B. Moistening inhaled air
• C. Producing mucus
• D. Propelling mucus upwards towards the throat

Correct answer: C

Rationale: The correct answer is C: 'Producing mucus.' Cilia lining the respiratory tract do not produce mucus, but rather move the mucus that is produced by other cells. The cilia work together to propel the mucus upwards towards the throat, where it can be either swallowed or expelled. Trapping inhaled dust and debris, moistening inhaled air, and propelling mucus upwards are all important functions of the cilia in the respiratory tract, helping to protect the lungs and maintain respiratory health.

6. Which hormone, produced by the pituitary gland, stimulates the production of milk in mammary glands during breastfeeding?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: c

Rationale: The correct answer is C: Prolactin. Prolactin is the hormone produced by the pituitary gland that stimulates the production of milk in the mammary glands during breastfeeding. It plays a crucial role in lactation by promoting the growth and development of the mammary glands and initiating the production of milk. Growth hormone (GH) regulates growth and metabolism, not milk production. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, not mammary glands. Follicle-stimulating hormone (FSH) is involved in reproductive processes, not milk production. Therefore, prolactin is the hormone directly responsible for stimulating milk production during breastfeeding.
