What rhetorical device is used in the following quote from the Great Gatsby, Chapter 8 :
"I have an idea that Gatsby himself didn’t believe it would come and perhaps he no longer cared. If that was true he must have felt that he had lost the old warm world, paid a high price for living too long with a single dream. He must have looked up at an unfamiliar sky through frightening leaves and shivered as he found what a grotesque thing a rose is and how raw the sunlight was upon the scarcely created grass. A new world, material without being real, where poor ghosts, breathing dreams like air, drifted fortuitously about…like that ashen, fantastic figure gliding toward him through the amorphous trees."1 AnswerHomework Help1 decade ago
I am a high-school student and I'm in a class about web designing and while working in Adobe/Macromedia Flash and I re-created a scene from South Park which shows the four boys at the bus stop and my teacher says i can't use these images because they are infringing copyright laws. I know that she's completely wrong and stupid for saying such a dumb thing, but can someone point me to a credible source that clearly shows that I am not, in fact, infringing copyrights.7 AnswersLaw & Ethics1 decade ago
