One piece of the stage setting that distinguishes our town from other plays of the time a) the lack of any setting at all
b) the heavy use of music
c) the fact that the curtains do not close between acts
d) that the play was written as a movie before being turned into a play

The correct answer is Option C) "the fact that the curtains do not close between acts".

Explanation:

The play "Our Town" by the American author Thornton Wilder is famous for having "no curtains and no scenery". Unlike most plays, the curtains do not close between acts. This is part of the playwright's way to tell the story, which has a minimalist style. This style also includes the actors performing in an almost bare stage and not using any props. The usage of minimalism in theater maintains the focus on the actors' dialogues and actions.
