• D. The potential energy of an object

Correct answer: a

Rationale: Power is defined as the rate at which work is done or the rate at which energy is transferred or converted.

4. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

• A. It is the only viable solution to the problem and should be prioritized.
• B. It is a promising approach but requires further research and development.
• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

5. Stephanie delegates effectively if she has authority to act, which is BEST defined as:

• A. having responsibility to direct others
• B. being accountable to the organization
• C. having legitimate right to act
• D. telling others what to do

Correct answer: A

Rationale: The correct answer is A: 'having responsibility to direct others.' Effective delegation involves entrusting tasks and responsibilities to others while still maintaining ultimate accountability. Authority to act means having the responsibility to direct others, making decisions, and overseeing the completion of tasks. This definition aligns with the core concept of delegation, where individuals are empowered and authorized to carry out specific duties. Being accountable to the organization (option B) is important but does not fully capture the proactive nature of delegation. Having a legitimate right to act (option C) is essential for effective delegation, but it is more about the formal authorization rather than the active responsibility to direct others. Simply telling others what to do (option D) is a narrow and authoritarian view of delegation that does not encompass the collaborative and empowering nature of effective delegation.

6. What is the scientific term for the windpipe, a tube that carries air from the larynx to the bronchi?

• A. Pharynx
• B. Trachea
• C. Epiglottis
• D. Bronchiole

Correct answer: B

Rationale: The correct answer is B: Trachea. The trachea is the scientific term for the windpipe, which is a tube that carries air from the larynx to the bronchi. The pharynx is the throat area where the mouth and nasal passages meet. The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food from entering the airway. Bronchioles are smaller airway branches in the lungs. Therefore, the trachea best fits the description of a tube carrying air from the larynx to the bronchi.
