the question is: Trace the development of the narrator, Nick Carraway – how does he change, and how are these changes significant (how do they relate to the themes of the novel)?
I need it plagiarism free besides the quotes of course
1 to 2 quotes per paragraph
you can only use the book (the great gatsby) and I already wrote the question the essay is about at the top of the instructions.
I need to know what page number the quotes are from.
