From the passage we learn that a blend of fiction and history _____ .

The novelist E. L. Doctorow is best known for his mixing
fiction with historical fact, by placing his stories within the
framework of public events. In fact, by integrating the
front-page news of the 20th century America with the lives
of his characters, Doctorow gives readers the ‘feel' of an
era, combining the unusual and the commonplace. His
latest novel ‘World's Fair' shows how the events of the
turbulent 1930s helped mold the sensibilities of his young
protagonist.
