Let’s say I do not know anything on the topic, can I turn in a paper that is mostly other sources?

This is not a good idea. The whole point of a paper or assignment is for the audience (your professor) to hear your voice and understand your thoughts on a topic. You will have to do some reading and research to learn more about the topic and then write about it. Use quotes from other sources to a minimum, they should not out-shine you. Also, you need to double check with your professor to ensure you are on the right track and ensure your understand what they are looking for in your paper.
