I’m stuck on a Art & Design question and need an explanation.

Chapter 8 (Scenery/Scenic Design)

Do you think it is possible for a play/musical to match or rival a movie in terms of the scenic design? Why or why not? Would you be a good scenic designer? Why or why not? Write 2-3 sentences.

Chapter 9 (Costumes/Costume Design)

Why are costumes important (or not) in theatre? Briefly describe a time when you had to make a costume or at least an accessory that you wore.

What basically does a scenic designer do?

What does a costume designer do? In your opinion, who is more important to a theatrical production, a scenic design or a costume designer?
