Well, we know that setting is location and surroundings, usually! Irony/sarcasm doesn't apply here, as it's usually in the form of dialogue or much more than those statements.Even if you were confused about tragic resolution, you know enough that there isn't anything particularly 'tragic' nor 'resolving' about this excerpt. So characterization seems best fit, giving an idea on the individual and their attire and how they are interacting with the other!

In this excerpt, the people from Arkansas who decided to go see the show are extremely unhappy with the way it turned out.

Therefore, instead of telling everyone else how deceptive the practice was, they will keep it secret out of embarrasment. Moreover, they will advise everyone to go see the play. Therefore, it is clear that the townspeople are afraid of being seen as gullible.
