Explanation: In literature, the theme is the underlying message of a story, it is what critical belief about life is the author trying to convey in the writing of a novel, play, short story or poem. Usually this belief, or idea, is universal and transcends cultural barriers. In the given excerpt from "The Tell-Tale Heart" we can see developed the theme corresponding to option D: Evil cannot stay hidden for long, because the speaker admit his crime because he cannot stand the beating of the man's heart.
This is a theme because it is a concept NOT the story line. A plot summary is basically the story line as if you were writing a summary of the book or story.
I thought it was going to be a tiger or a leopard at first because of the different colors and accents. The spots made me think it was a leopard but then the little bit of orange on his forehead made me think it was a tiger but now I'm just thinking it's an Indian trying to blend in with his environment.
