1. What is the function of the Vas Deferens?
- A. Produces fluid to increase sperm mobility
- B. Site where the egg matures
- C. Helps control urine flow
- D. Connects each testis to the urethra
Correct answer: D
Rationale: The vas deferens is a duct that connects each testis to the urethra, allowing the transport of sperm. Choice A is incorrect because the vas deferens does not produce fluid to increase sperm mobility. Choice B is incorrect as the vas deferens is not a site for egg maturation. Choice C is incorrect as the vas deferens does not help control urine flow, its primary role is in the transport of sperm.
2. How does urine flow through the urethra?
- A. Continuously
- B. Only when the bladder is completely full
- C. Under voluntary control of sphincter muscles
- D. A combination of B and C
Correct answer: C
Rationale: Urine flows through the urethra under voluntary control of sphincter muscles. These muscles can be consciously contracted or relaxed to control the flow of urine from the bladder to the outside of the body. Choice A is incorrect as urine flow is not continuous but rather regulated. Choice B is incorrect because urine flow is not restricted to only when the bladder is completely full. Choice D is incorrect as it inaccurately combines the two incorrect statements of choices B and C.
3. Solve for x: 3(x - 1) = 2(3x - 9)
- A. x = 2
- B. x = 8/3
- C. x = -5
- D. x = 5
Correct answer: D
Rationale: To solve the equation 3(x - 1) = 2(3x - 9), first distribute and simplify both sides to get 3x - 3 = 6x - 18. Next, subtract 3x from both sides to get -3 = 3x - 18. Then, add 18 to both sides to obtain 15 = 3x. Finally, divide by 3 to find x = 5. Therefore, the correct answer is x = 5. Choices A, B, and C are incorrect because they do not represent the correct solution to the given equation after proper algebraic manipulation.
4. What can one reasonably conclude from the final comment of this passage? 'If he be Mr. Hyde,' he had thought, 'I should be Mr. Seek.'
- A. The speaker is considering changing names.
- B. The speaker is experiencing a determination to find Hyde.
- C. The speaker has mistakenly been looking for the wrong person.
- D. The speaker intends to continue to look for Hyde.
Correct answer: D
Rationale: The correct answer is D. The speaker's final comment indicates a determination to keep looking for Hyde, as he expresses his intention to become 'Mr. Seek' if the other person is indeed 'Mr. Hyde.' This shows that the speaker is persistent in his search for Hyde, as he believes that discovering Hyde's identity could potentially unravel the mystery and clarify his friend's strange behavior. Choices A, B, and C are incorrect because the final comment does not imply a name change, an identity crisis, or a mistaken search but rather a firm decision to continue seeking out Hyde.
5. Which of the following is a complete sentence?
- A. Under the bed.
- B. Although he tried his best.
- C. Running through the park.
- D. She ran through the park.
Correct answer: D
Rationale: The correct answer is D, 'She ran through the park.' This sentence is a complete sentence as it contains both a subject 'She' and a predicate 'ran through the park.' Choices A, B, and C are not complete sentences because they lack either a subject, a predicate, or both. Choice A 'Under the bed.' lacks a verb or predicate, choice B 'Although he tried his best.' is a dependent clause and does not form a complete sentence on its own, and choice C 'Running through the park.' is a phrase without a subject or a complete predicate.
