Answer:
1. He changed it at the age of 17. At the specific moment that witnessed the beginning of his career, when he saw Dan Cody's yacht drop anchor over the most insidious flat on Lake Superior, it's more glamorous and sophisticated.
2. Dreams of glory kept Gatsby up at night..... an endless desire to have more and be more..... the desire to make himself worthy of Daisy.
3. It represents all the beauty, glamor, and success in the world.
4. Some legal device was used against him; all the money went to Ella Kaye. She cheated Gatsby out of it.
5. Men and women had different standards (double standards) where the woman would stay home and be the good wife. The man could go out. Obviously, Tom doesn't like Daisy running around and still believes in these old-fashioned standards, making him sexist and hypocritical.
6. She doesn't like it; it offends her in the way that it's West Egg's new money where everybody is tacky, wild, and drunk. She's elite, and the party doesn't live up to her classy standards of East Egg. It appalls her.
7. Gatsby is new money--tacky, flashy, and showing it off. He wasn't born into privilege, so he thinks like West Eggers. In contrast, Tom and Daisy are classy old money people with standards and sophistication. They're snobby, and the party is below them, but Gatsby doesn't understand because he isn't sophisticated like East Eggers.
8. Nick knows that you can't and shouldn't repeat the past, but Gatsby thinks he can erase the last five years and start over again. His opinion is unrealistic because it's been five years, and both of them have changed. Daisy has a daughter--you can't hit the undo button.
