The most objective and complete summary of the fable by Mark Twain is:
A. The story is a fable about a cat who tries to show its animal friends a picture. The friends all make the mistake of standing between a mirror and the picture, so they only see themselves—not the picture. Because they all see something different, they each mistakenly think the others are lying. The cat summarizes the story’s moral, which is that one will see what one expects to see in a text if they are not careful to look past their own ideas.
This summary captures the main elements of the story, including the characters, their actions, the confusion that arises, and the moral lesson conveyed.
