1. What is the function of the epiglottis?

• A. Produces saliva
• B. Senses taste
• C. Prevents food from entering the windpipe
• D. Filters blood

Correct answer: C

Rationale: Rationale: The epiglottis is a flap of cartilage located at the base of the tongue that covers the opening of the windpipe (trachea) during swallowing to prevent food and liquids from entering the airway. This action ensures that food and liquids are directed to the esophagus and down into the stomach, rather than entering the respiratory system, which could lead to choking or aspiration pneumonia. The other options (A) Produces saliva, (B) Senses taste, and (D) Filters blood are functions of other structures in the body and are not related to the role of the epiglottis.

2. What is the difference between heat and temperature?

• A. They are the same thing.
• B. Heat is a form of energy, while temperature measures the average kinetic energy of particles.
• C. Heat flows from cold to hot, while temperature flows from hot to cold.
• D. Heat is measured in Celsius, while temperature is measured in Joules.

Correct answer: B

Rationale: Heat is a form of energy transfer, while temperature reflects the average kinetic energy of particles within a substance.

3. He likewise stresses the need for all the employees to follow orders and instructions from

• A. Scalar chain
• B. Discipline
• C. Unity of command
• D. Order

Correct answer: B

Rationale: The correct answer is B: 'Discipline.' In a business context, discipline refers to the adherence to rules, orders, and instructions to ensure smooth operations and efficiency. The concept of discipline is essential in maintaining order, consistency, and productivity within an organization. It encompasses obeying rules, following instructions, and respecting authority. While the other options like 'Scalar chain,' 'Unity of command,' and 'Order' are important principles in management, they do not directly address the importance of employees adhering to orders and instructions, which is the central focus in this question. Therefore, 'Discipline' is the most suitable answer in this context.

4. Which property of a substance describes its ability to conduct heat or electricity?

• A. Reactivity
• B. Conductivity
• C. Density
• D. Viscosity

Correct answer: b

Rationale: Conductivity refers to a substance's ability to conduct heat or electricity

5. A ball is thrown horizontally off a cliff. Which of the following forces is responsible for its downward motion?

• A. The force of throwing
• B. Normal force from the air
• C. Tension force from the string (if used)
• D. Gravitational force

Correct answer: D

Rationale: The gravitational force is responsible for the downward motion of the ball. When the ball is thrown horizontally off a cliff, the only force acting on it in the vertical direction is the force of gravity, which pulls the ball downward towards the ground. The other forces mentioned (force of throwing, normal force from the air, tension force from the string) do not contribute to the ball's downward motion in this scenario.

6. When ice melts, it undergoes a…

• A. Chemical change
• B. Physical change
• C. Nuclear change
• D. Radioactive decay

Correct answer: B

Rationale: Melting is a change in physical state, not a change in the chemical composition of the ice.
