What's the significance of your paper?
What's unique about your paper?
This kind of question is very common, as long as you are familiar with your paper.
Problem:
The teacher may pick out something you wrote in great detail and ask, for example, others think this character is like this, why do you think it is like that, but these two views are just the opposite?
During the defense, the teacher asked me: I wrote The Legend of Narnia by C.S. Lewis. The teacher asked: Will Narnia written by the author really come true? This is difficult to answer, because it is possible from the author's point of view and almost impossible from the realistic point of view.
Generally, you don't turn over the papers when you reply. Because on the one hand, you must be familiar with your paper, on the other hand, you can't read the answers to the questions raised by the teacher well. Unless the teacher says turn to a page, what do you think of this page and explain why? This will turn the paper over.
The teacher sometimes doesn't ask any difficult questions, but only points out where your paper has been revised. Because after the final defense, the final draft will be submitted for the record, and the format will continue to be changed.
Suggestion: To have a certain understanding of your own bibliography, some teachers will ask what opinions a document has, and generally just answer these questions, so you need to know what documents you have used.
In short, don't be too nervous. The teacher will definitely let you live. If you don't graduate, he will give himself early trouble. Hehe, I wish you a successful defense!
