Student Essay Excerpt:
Gatsby's mansion represents his ambitious dreams. His extravagant parties and carefully curated image demonstrate his desperate attempt to win Daisy's attention.

Like the green light that Gatsby reaches for across the bay, his mansion symbolizes the hollowness of materialism in pursuing the American Dream.
