Final answer:

Step-by-step explanation:
The most important and most difficult challenge an author faces is recreating the story. Each artist who turns to this subject has a challenge: how does one preserve the perceived accuracy and authority of the image, while creating a work that is new, fresh, and effective? One way for the author to go is to "fill in" what history does not tell us, that is, to create a story about what "might have happened." Another approach for writers of historical material is to use a factual setting and create fictional characters who take their places in a plot developing against a historical backdrop.
