Final answer:
The word supervises suggests that someone is observing and directing activities or tasks, which aligns with the meaning 'watches' rather than 'encourages' or 'judges'.
Step-by-step explanation:
The word supervises in paragraph 6 most likely means watches over someone or something to ensure that everything is done correctly, safely, and/or efficiently. Supervising does not necessarily involve encouragement, which is more about motivation, nor judging, which is about forming and expressing a critical opinion. Instead, supervises indicates that someone is observing and directing the performance of a task or the activities of a person.
