1. Which hormone is crucial for stimulating sperm production in males?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Insulin

Correct answer: C

Rationale: Testosterone is the hormone crucial for stimulating sperm production in males. It is primarily produced in the testes and plays a significant role in the development of male reproductive tissues, including the testes and prostate, as well as promoting secondary sexual characteristics such as facial hair growth and deepening of the voice. Estrogen and progesterone are female sex hormones responsible for regulating the menstrual cycle and other female reproductive functions. Insulin, on the other hand, is involved in regulating blood sugar levels and glucose metabolism, not directly related to sperm production in males.

3. Which word best completes the sentence: 'The students _______ finished their exams.'

• A. has
• B. have
• C. is
• D. was

Correct answer: B

Rationale: In the sentence, 'The students' is referring to a plural subject. Since 'students' is plural, the correct verb should also be plural. 'Have' is the correct verb form for the plural subject 'students' in this sentence.

Therefore, the correct choice is B: 'have.'

4. Why is The Importance of Being Earnest considered one of Wilde's most enduring works?

• A. Because it offers a deep and serious critique of society.
• B. Because it humorously exposes the flaws of the upper class.
• C. Because it captures the essence of Wilde's witty and satirical style.
• D. Because it reflects Wilde's deep personal struggles with society.

Correct answer: C

Rationale: The play endures because it perfectly captures Wilde's witty and satirical style, making it a timeless critique of society. 'The Importance of Being Earnest' humorously exposes the flaws of the upper class, rather than offering a deep and serious critique of society (Choice A). While Wilde's personal struggles may have influenced his works, 'The Importance of Being Earnest' is more focused on societal critiques through wit and satire, rather than reflecting his personal struggles (Choice D). Although the play does humorously expose the flaws of the upper class, the main reason for its enduring popularity is its embodiment of Wilde's witty and satirical style (Choice B). Therefore, Choice C is the correct answer.

5. What is the primary function of the large intestine?

• A. absorbing digested material into the blood
• B. nutrient processing and metabolizing
• C. absorbing water and compacting material into solid waste
• D. bile production and storage

Correct answer: C

Rationale: The large intestine's primary function is to absorb water from undigested food remnants and compact them into solid waste (feces). This process helps regulate hydration levels in the body and aids in waste elimination. Choices A, B, and D are incorrect. Absorbing digested material into the blood is mainly done in the small intestine, nutrient processing and metabolizing occur in various parts of the digestive system, and bile production and storage are functions of the liver and gallbladder, not the large intestine.
