Your paper must supply evidence for your argument. In the main, this should come from the primary text/s you cite. If you think a passage reveals an important idea about the aspect of the work you discuss, you should cite it. Just as it's important to avoid paraphrasing a work (summing up its plot), it's important to select evidence carefully (don't string quotes together one after another to fill up space with redundant examples). Your paper must argue the details of the text, not general ideas; the more detailed the evidence, the more persuasive the case. Your evidence will reveal your sensitivity to language and how authors use it .
