How many edges has a square​

If you were to stage the play on which casablanca is based, how would you use lighting in your production? describe one scene from the film and the lighting it uses. would you change the lighting in any way for a stage production of the scene? why or why not?

Ineed someone to describe what they mean in the instructions !
