You were incorrect when you selected "exposition" because exposition refers to the part of a story that provides background information, such as details about the setting, characters, or events. It doesn't involve the use of objects or ideas to represent deeper meanings.
The correct answer is "symbolism." Symbolism is a literary technique where an object, idea, or character represents something beyond its literal meaning. For example, if a character in a story carries a broken clock, it might symbolize their struggle with time, missed opportunities, or the feeling that their life is out of control.
In Auggie’s writing, simple objects or ideas can represent complex emotions or themes, which is a hallmark of symbolism. This technique helps to deepen the reader's understanding of the story and adds layers of meaning.
