Answer Details
Flashbacks in a literary work serve several purposes, but they primarily help to place the story in proper perspective by providing the reader with necessary background information. They can help to fill in missing links in the plot, explain character motivations, and provide context for the events taking place in the present timeline. Additionally, flashbacks can reveal the characters' mindsets and emotional states at the time of the events being recalled, which can deepen the reader's understanding and empathy for the characters. Flashbacks are not meant to relate events that are extraneous to the story, but rather to enhance the narrative by providing a more complete picture of the story and its characters.
