What aspects of realism does the story "editha" include? cite evidence from the text to support your answer

In "Editha," Howells uses characters to build the theme and the plot of the story, an approach that is a major aspect of realist literature. The story itself revolves around the theme of realistic and truthful portrayal of events in contrast to a romantic, idealized version.  Editha's character moves the plot along. The author uses her character to show how newspapers and magazines tend to glorify war and how they influenced society. Editha’s ignorance, for instance, is displayed when she echoes newspaper stories. Mrs. Gearson plays the foil to the fickle Editha. The author gives her dialogue such as "What a thing it is to have a country that can't be wrong, but if it is, is right, anyway!" to portray the deceptiveness of political wars, where people are led into believing in the righteousness of their country and its actions irrespective of the truth. The author upholds the idea of truth through the end with George's death.
