Jekyll and Hyde

Hello, I do Jekyll and Hyde edexcel for lit. I was really struggling one to pick out the best quotes because obviously the questions won't always be specific like the quotes need to be appliable to every question and second im not really sure how to write a good paragraph, like since we don't really analyse language for part b even some of the key quotes such as man is not truly one but truly two idk what to write for it. Can some one help or write a model para and guide me through
