It is the settings because a setting mention to the physical action of an artist on stage that will influence the response of the audience. It is very key in a drama or theater. If an artist is not doing an suitable actions based on the story, the audience will not get the memo that the artist relay. Settings are not typically established in other written stories because there are no audiences rather only readers. so settings are well defined in dramas or theater.
It introduces what the text will be about and why they strongly believe that the only fear u should worry about is fear itself.
