1. During sexual intercourse, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

• A. Vas deferens
• B. Epididymis
• C. Seminal vesicle
• D. Urethra

Correct answer: A

Rationale: The correct answer is A: 'Vas deferens.' The vas deferens is a tube that carries sperm from the testes to the urethra during ejaculation. It is a crucial part of the male reproductive system, allowing for the transport of sperm for fertilization. The epididymis is where sperm mature and are stored, not where they travel during intercourse. The seminal vesicle is a gland that produces a significant portion of the seminal fluid. The urethra is the tube that carries both urine and semen out of the body but is not where sperm travels from the testes.

2. Relatively prime numbers share no common factors other than 1. Which of the following pairs of numbers are relatively prime?

• A. 12 and 16
• B. 15 and 17
• C. 20 and 24
• D. 28 and 36

Correct answer: B

Rationale: Rationale: - Relatively prime numbers are numbers that share no common factors other than 1. - To determine if two numbers are relatively prime, we need to find the greatest common divisor (GCD) of the two numbers. If the GCD is 1, then the numbers are relatively prime. - Let's calculate the GCD for each pair of numbers: A) GCD(12, 16) = 4, not relatively prime B) GCD(15, 17) = 1, relatively prime C) GCD(20, 24) = 4, not relatively prime D) GCD(28, 36) = 4, not relatively prime Therefore, the pair of numbers 15 and 17 are relatively prime because their greatest common divisor is 1, meaning they share no common factors other than 1.

3. He emphasizes to the team that they need to put their efforts together towards the attainment

• A. Span of control
• B. Unity of direction
• C. Unity of command
• D. Command responsibility

Correct answer: B

Rationale: The correct answer is B: Unity of direction. Unity of direction is a principle of management which states that all activities within an organization should be directed towards the same objectives. In this scenario, the leader is stressing the importance of aligning the team's efforts towards a common goal or objective. This ensures that everyone is working towards a shared purpose, avoiding conflicting or contradictory actions. Span of control refers to the number of subordinates a manager can effectively supervise. Unity of command relates to the principle that employees should receive orders from only one supervisor to avoid confusion and conflict. Command responsibility is a term often used in the context of accountability for actions taken under one's command. Therefore, the most appropriate concept in this context is Unity of direction.

4. Which property of a wave remains constant when it crosses a boundary between two different media?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Speed

Correct answer: d

Rationale: The speed of a wave remains constant when it crosses a boundary between two different media, although its direction may change.

5. What is the common name for the organic compound CH₃OH?

• A. Methane
• B. Ethanol
• C. Methanol
• D. Butanol

Correct answer: C

Rationale: CH₃OH is commonly known as methanol. The other choices represent different organic compounds.

6. What is the primary factor that determines whether a solute will dissolve in a solvent?

• A. Temperature
• B. Pressure
• C. Molecular structure
• D. Particle size

Correct answer: c

Rationale: The molecular structure of the solute and solvent plays a key role in determining solubility. The other choices may influence solubility but are not the primary determining factor.
