What is a prologue in a literary work?

A prologue serves as an introductory section in a literary work, meant to provide context, background information, or set the tone for the main story that follows. It often gives readers insight into characters, events, or themes that are significant to understanding the plot. By including a prologue, the author has the opportunity to engage readers right from the start, setting the stage and creating anticipation for the narrative to come.

In contrast, an epilogue, which is incorrectly described in the first choice, occurs at the end of a story to wrap up loose ends, while summarization of the book is typically found in a blurb or synopsis rather than in a prologue. Additionally, the concept of a short dialogue between characters does not align with the purpose of a prologue, as it lacks the broader function of establishing themes or narratives that precede the main text. Thus, identifying a prologue as an introductory section that sets the stage for the main story reflects its role in literature accurately and comprehensively.
