What is one way authors establish a setting in their narratives?

Authors establish a setting in their narratives primarily through detailed descriptions of time, place, and environment. This allows readers to visualize where and when the story takes place, creating a backdrop that enhances the overall narrative. By providing vivid details about the physical landscape, the atmosphere, and the historical context, authors can evoke certain emotions and reactions from their readers, making the story more immersive. This context gives readers a frame of reference to better understand the characters' actions and the plot's development.

The other options may contribute to a story's depth or development, but they do not focus specifically on creating a sense of place and time as effectively as detailed descriptions do. For example, introducing characters and their dialogues mainly focuses on character development rather than setting. Outlining themes and morals speaks to the overarching messages of the narrative rather than its environment, and complex sentence structures or vocabulary pertain more to style than to establishing the setting.
