Read the excerpt from trifles.

mrs. hale. duty’s all right, but i guess that deputy sheriff that came out to make the fire might have got a little of this on. (gives the roller towel a pull.) wish i’d thought of that sooner. seems mean to talk about her for not having things slicked up when she had to come away in such a hurry.

mrs. peters. (who has gone to a small table in the left rear corner of the room, and lifted on end of a towel that covers a pan). she had bread set. (stands still.)

how would an audio recording of this excerpt establish the setting of the play?

a. through the characters’ expressions as they talk
b. through the changing tones of the characters’ voices
c. through the use of props such as the roller towel
d. through the sound effect of footsteps around the kitchen
