The quote "Gatsby believed in the green light, the orgastic future that year by year recedes before us" aligns with the theme of the American Dream in 'The Great Gatsby', symbolizing the pursuit of unattainable aspirations.
Step-by-step explanation:
The quote that best 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 quote encapsulates the elusive nature of the American Dream, representing a perpetual desire for a brighter future that is always out of reach, much like Gatsby's longing for Daisy and what she represents. The green light, situated at the end of Daisy's dock, becomes a symbol of Gatsby's dreams and aspirations, signaling the distant and unattainable nature of these wishes.
