Read the following scene from trifles.

county attorney. let’s talk about that later, mr. hale. i do want to talk about that, but tell now just what happened when you got to the house.

hale. i didn’t hear or see anything; i knocked at the door, and still it was all quiet inside. i knew they must be up, it was past eight o’clock. so i knocked again, and i thought i heard somebody say, “come in.” i wasn’t sure, i’m not sure yet, but i opened the door—this door (indicating the door by which the two women are still standing), and there in that rocker—(pointing to it) sat mrs. wright. (they all look at the rocker.)

what would be one advantage of watching this scene as opposed to reading it?

"Trifles" is a one-act play written by author Susan Gaspell. It was first performed at the Wharf Theater in Massachusetts on August 8th, 1916. It tells the story of how Mr Hale found Mrs Wright acting strangely while her husband was strangled by a rope in the room upstairs. The whole play happens while Mr Hale is recounting the events to the county attorney at the farm house.

The advantage of watching the scene described in the question as opposed to reading it, would be that the audience would be able to watch all of the interactions that the characters make, and not only read about them. When Mr Hale points at the rocker or at the women standing at the door, the audience would be able to look at the things he is pointing at. This would bring more detail to the scene and therefore the audience's experience would be enhanced.
