I will not write your assignment for you, but here is how you can come up with ideas. What have you seen in the most solemn or sacred occasions you have witnessed? At a funeral for example, or when paying respect to a soldier who has died, what do we usually do? What are some religious practices you have seen in your own life or in the lives of others?
Regarding authority, consider some of the leaders you have seen in your lifetime. What makes them look like a leader? Do they wear a uniform of some kind? Do they have a badge?
Let me know if that helps!
