If you study characters, the plot, the setting, and the <u>tone,</u> you can often deduce a story's theme.
A theme is the central idea or purpose for writing a story or article. Alternatively, a plot is the way a story is structured or arranged.
Characters are the actors or the people involved in a story. Tone is the way the author writes that affects the mood of the readers. Setting is the place the action in a story occurs.
As a result of this, if a person wants to find the theme of a story, then knowing the characters, plot, setting and tone would help somone easily know it.
I would say that sometimes you would not 'identify' a mistake in your head. Also if you read it out loud you might realize how it does not make sense in your sentence.
