The most evident element of literature in the provided excerpt from 'The Great Gatsby' is the setting, described vividly by F. Scott Fitzgerald.
Step-by-step explanation:
In the excerpt from The Great Gatsby by F. Scott Fitzgerald, the element of literature most evident is setting. Fitzgerald uses vivid description to paint the physical landscape of Long Island, which serves as a crucial backdrop to the story's events.
The imagery of 'enormous eggs' and 'the great wet barnyard of Long Island Sound' not only sets the scene but also hints at the social and moral contrasts between the East Egg and West Egg communities. This detailed depiction goes beyond mere location, suggesting themes and social commentary that are central to the narrative.
