Question

How would an audio recording of this excerpt help establish the setting of the play?
through an increase in volume at certain points in time
through the dialogue spoken by each of the characters
through the sound of a cupboard door opening
through a change in the characters’ tones of voices

Answer 1

through the sound of a cupboard door opening

A sound effect like a cupboard door opening gives a concrete clue about the physical place (e.g., a kitchen or pantry) and helps listeners imagine the scene. Dialogue can also help, but the cupboard sound directly establishes setting in audio.
