how does the description of the setting contribute to the plot of the text ?

Trifles is filled with a strong sense of place. The characters in the play are deeply rooted in their rural environment. Lewis Hale was on his way into town with a load of potatoes when he stopped by the Wright's house to see about sharing a party line telephone, a common way for people in small communities to afford phone service during the first few decades of the century. The lives of the women seem to consist of housekeeping chores, food preparation, sewing, and raising children, with little time left for socializing. The characters' manner of speech reveals their limited education and rural, Midwestern environment.
