What does my instructor mean when she says I can only use quotes or block quotes twice in my paper? It has to be MLA format.
Your instructor means that you can only directly quote (word for word) your sources twice in your paper. All other times, you must paraphrase, or use your own words to describe what the source says.
In MLA format, a long quote is four or more lines, and must be in block format. Click the Purdue Owl MLA Guide link below for more information on short and long quotes.
Generally speaking you want to make your own arguments, using your sources as support.
