1. Which property of a wave represents the distance between two successive identical points on a wave?

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

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

• A. 4:00 PM
• B. 6:00 PM
• C. 8:00 PM
• D. 10:00 PM

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

3. Which of the following is the primary function of the lymphatic system?

• A. Transporting oxygen and nutrients to cells
• B. Carrying waste products away from tissues
• C. Regulating body temperature
• D. Producing red blood cells

Correct answer: B

Rationale: The correct answer is B: 'Carrying waste products away from tissues.' The primary function of the lymphatic system is to collect excess fluid from tissues and return it to the bloodstream, while also transporting waste products, pathogens, and cellular debris away from tissues to be filtered and eliminated. This helps maintain fluid balance in the body and supports the immune system by removing harmful substances. Options A, C, and D do not accurately describe the primary function of the lymphatic system, making them incorrect choices.

4. The unit for measuring luminous flux, which describes the perceived brightness of a light source by the human eye, is:

• A. Candela
• B. Lumen
• C. Lux
• D. Hertz

Correct answer: A

Rationale: The correct answer is B: Lumen. Luminous flux is the measure of the total quantity of visible light emitted by a source per unit time, measured in lumens. The candela (A) is the unit for luminous intensity, lux (C) is the unit for illuminance (luminous flux per unit area), and Hertz (D) is the unit for frequency. Therefore, in this question, the unit for measuring luminous flux is the lumen, as it specifically quantifies the perceived brightness of a light source by the human eye.

5. One leadership theory states that “leaders are born and not made,” which refers to which of the

• A. Trait
• B. Charismatic
• C. Great Man
• D. Situational

Correct answer: A

Rationale: The correct answer is A: Trait. The statement 'leaders are born and not made' aligns with the Trait theory of leadership, which suggests that certain individuals are born with innate qualities and characteristics that make them effective leaders. This theory focuses on identifying specific traits, such as intelligence, charisma, and self-confidence, that are believed to be inherent in successful leaders. Charismatic leadership (option B) emphasizes the charm and appeal of a leader, Great Man theory (option C) suggests that leaders are born with unique qualities that set them apart, and Situational leadership (option D) focuses on adapting leadership style based on the situation. However, the statement in the question best corresponds to the Trait theory, making option A the correct choice.

• A. This movie is good, but the other one is better.
• B. She is the tallest player on the team.
• C. He worked hardest than everyone else.

Correct answer: A

Rationale: Option A uses "better" to compare the quality of two movies.
