number 2 is when the narrator states, "i can see now this has beeen a story of the West after all" what does this mean... can anyone give me examples from the book.

at the last one number 3 is does anyone know the significance of the green light, always visible at the end of Daisys peir. and if anyone has any examples from the book again that would be great..

thank you to who ever helps me.

#3 . . . The green light is a sign of hope for Gatsby.  He sees that light and buys the house across the water so that he can be near Daisy and entice her to come to one of his lavish parties.  He has finally found her, and he believes he has the "green light" to woo her.

OK.

In the Great Gatsby, by Fitzgerald, The West Egg is like the American West.  It's a frontier.  It's innocent and optimistic, like Nick and Jay Gatz.  It's new-money. The East Egg is the establishment.  It's corrupt and drunk and jaded, like Tom and Daisy.
Even though Tom and Daisy are originally from the West, living a wealthy life on East Egg has destroyed their innocent optimism; they become "careless people who destroyed other people's lives."
The Great Gatsby is a story about the heady optimism of the 1920's.  That's why it's a story about the West and how it's destroyed by the East.
