Della cut her hair, and sold it to buy a chain for Jim's watch. Jim, sold his watch to buy Della combs for her hair. The answer should be Della was <span>so excited to have the combs she had wanted, that she momentarily forgets she has cut her hair. She cries as she realizes she will not be able to use them.
The other answers don't really fit in with the story.
Hope this helps!:)</span>
For fiction, I think that the plot should tell a story such as in the history of something or someone and describe the main characters and how they are related to the story such as Jack London's Martin Eden which discusses a lot the feelings of the main protagonist working class character and his relationship to his girlfriends rich parents and their very different perspectives on life.
