Answer and explanation:
In literature, exposition is the part of a story in which the author sets the stage for what will happen. It is where the theme, characters, conflicts, setting and/or circumstances are laid out. It is during the exposition that we get to know some fundamental facts about the characters that will help us understand who they are and keep up with their development through the story.

We need to know a bit about the characters to feel connected to them.
