1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. 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.

3. Which type of glial cell provides structural support and insulation for neurons in the central nervous system?

• A. Schwann cells
• B. Astrocytes
• C. Oligodendrocytes
• D. Microglia

Correct answer: C

Rationale: The correct answer is C: Oligodendrocytes. Oligodendrocytes are a type of glial cell found in the central nervous system that provide structural support and insulation for neurons by forming myelin sheaths around axons. Schwann cells, on the other hand, are found in the peripheral nervous system. Astrocytes play a role in nutrient transfer and maintaining the blood-brain barrier. Microglia are responsible for immune defense and clearing debris in the CNS. Therefore, oligodendrocytes are specifically responsible for providing structural support and insulation for neurons in the central nervous system.

4. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

• A. The table is much heavier than the book.
• B. The force on the book acts in a different direction.
• C. The table has a much larger surface area, distributing the force over a wider area
• D. All of the above

Correct answer: C

Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.

5. What is the main component of bile, a substance that aids in fat digestion?

• A. Proteins
• B. Carbohydrates
• C. Bile salts
• D. Vitamins

Correct answer: C

Rationale: Rationale: Bile is a digestive fluid produced by the liver and stored in the gallbladder. Bile salts are the main component of bile that aid in the digestion and absorption of fats in the small intestine. Bile salts help emulsify fats, breaking them down into smaller droplets that can be more easily digested by enzymes. Proteins, carbohydrates, and vitamins are not the main components of bile and do not play a significant role in fat digestion.

6. Which of the following conclusions of Ms. Castro about leadership characteristics is TRUE?

• A. There is a high correlation between the communication skills of a leader and the ability to get
• B. A manager is effective when he has the ability to plan well.
• C. Assessment of personal traits is a reliable tool for predicting a manager’s potential.
• D. There is good evidence that certain personal qualities favor success in managerial role.

Correct answer: A

Rationale: The correct answer is A because effective communication skills are essential for a leader to successfully convey ideas, motivate teams, and build relationships. Strong communication skills enable a leader to articulate goals clearly, listen to feedback, and resolve conflicts efficiently. This correlation between communication skills and leadership effectiveness has been well-documented in numerous studies. In contrast, options B, C, and D are not universally true statements about leadership characteristics. While planning skills and personal traits may contribute to effective leadership, they are not as directly linked to leadership success as communication skills. Therefore, option A is the most accurate conclusion about leadership characteristics among the choices provided.
