1. Define "friction" in terms of opposing motion.

• A. A force that increases motion
• B. A force that accelerates motion
• C. A force that opposes motion
• D. A force that creates motion

Correct answer: c

Rationale: Friction acts opposite to the direction of motion, resisting or slowing down the movement of objects.

2. Based on the passage, the author's stance on AI is likely to be

• A. Unconditionally enthusiastic, embracing all forms of AI development without reservations.
• B. Cautiously optimistic, acknowledging both the potential and risks while advocating for responsible use.
• C. Strongly critical, focusing solely on the potential dangers of AI and advocating for its complete halt.
• D. Apathetic and indifferent, lacking any strong opinion on the impact or future of AI.

Correct answer: B

Rationale: The emphasis on balancing benefits and risks suggests a cautious and balanced perspective, aligning with B.

3. What is the term for a solution that contains less solute than the maximum amount it could dissolve at a specific temperature and pressure?

• A. Saturated solution
• B. Unsaturated solution
• C. Supersaturated solution
• D. Concentrated solution

Correct answer: b

Rationale: An unsaturated solution is one in which less solute has dissolved than the maximum amount it could dissolve under specific conditions. The other choices do not accurately describe an unsaturated solution.

4. The neutral theory of molecular evolution proposes that:

• A. Most mutations in DNA are selectively neutral and do not affect an organism's fitness.
• B. All mutations are beneficial and contribute to the adaptation of a population.
• C. The rate of evolution is primarily driven by strong directional selection pressures.
• D. Genetic drift plays a negligible role in shaping genetic variation within populations.

Correct answer: A

Rationale: Rationale: A) The neutral theory of molecular evolution, proposed by Motoo Kimura in the 1960s, suggests that the majority of mutations that occur in DNA are selectively neutral, meaning they do not have a significant impact on an organism's fitness. These neutral mutations are not subject to natural selection and are allowed to accumulate in populations over time. This theory helps explain the high levels of genetic variation observed within populations. B) Option B is incorrect because not all mutations are beneficial. Mutations can be neutral, harmful, or beneficial, and the neutral theory specifically focuses on the idea that many mutations are neutral in their effects. C) Option C is incorrect because the neutral theory suggests that evolution is not primarily driven by strong directional selection pressures. Instead, it emphasizes the role of genetic drift and the accumulation of neutral mutations in shaping genetic variation. D) Option D is incorrect because

5. Julius orients his staff on the patterns of reporting relationship throughout the organization.

• A. Span of control
• B. Hierarchy
• C. Esprit d’ corps
• D. Unity of direction

Correct answer: B

Rationale: The correct answer is B: Hierarchy. Hierarchy refers to the structure of authority and responsibility within an organization, including the levels of management and the reporting relationships. In this scenario, Julius is orienting his staff on the patterns of reporting relationships, which is a key aspect of hierarchy. Span of control refers to the number of employees a manager can effectively supervise, esprit de corps pertains to team spirit and unity among employees, and unity of direction relates to ensuring all activities are focused on the same objectives. Therefore, the most appropriate term for Julius's action is hierarchy.

6. The external body covering, providing protection and contributing to temperature regulation, is composed of:

• A. Muscle tissue
• B. Epithelial tissue (skin)
• C. Bone marrow
• D. Cartilage

Correct answer: B

Rationale: The correct answer is B: Epithelial tissue (skin). The skin is the external body covering that provides protection against physical, chemical, and biological factors. It also plays a crucial role in regulating body temperature by controlling heat exchange with the environment through processes like sweating and blood vessel constriction or dilation. Muscle tissue (option A) is responsible for movement, bone marrow (option C) produces blood cells, and cartilage (option D) is a type of connective tissue found in joints. Therefore, epithelial tissue (skin) is the most suitable option as it directly addresses the functions of the external body covering.
