See if your teacher is interested in your paper. If so, he will ask a lot of knowledge involved in your paper, such as nouns, some examples in your article, such as the people involved in the article and so on. In short, he will ask anything.

Answer the question first, tell the truth, don't take it for granted that you can't play by yourself, the teacher will be very disgusted.

The second is to learn the skills of answering. For example, don't simply say that I won't answer questions that you can't answer, but tactfully convey the information that you can't answer to the teacher and let the teacher know why you can't answer.
