Final answer:
The quote that encapsulates the theme of the American Dream in 'The Great Gatsby' is 'Gatsby believed in the green light, the orgastic future that year by year recedes before us,' which illustrates the constant, elusive pursuit of one's dreams and hopes.
Step-by-step explanation:
The quote that supports the theme of the American Dream and the Green Light in "The Great Gatsby" is: "Gatsby believed in the green light, the orgastic future that year by year recedes before us." This line encapsulates the never-ending pursuit of the American Dream and the symbolic representation of the green light, which stands for Gatsby's hopes and dreams for the future, especially his desire to reconnect with Daisy. It reflects the idea that the dream seems within reach but is always just out of grasp, which is a central theme in the novel.
The quote aligns with the optimistic pursuit that characterized the 1920s, as the decade was a time of great economic prosperity and societal change. However, this optimism was often tempered by the harsh realities and eventual disenchantment felt by many, mirroring Gatsby's experience and the broader theme of the illusion versus the reality of the American Dream.
