Which of the following is an integral part of a play’s setting

Backdrop setting is when the setting is unimportant for the story and the story could take place in any setting. Winnie-the-Pooh by A. A. Milne is an example of a story in which could happen in any setting. Integral setting is when the action, character, or theme are influenced by the time and place, setting.

I suggest putting an image of the excerpt somewhere so people can actually see which specific excerpt you're referring to.
