听不懂问题或不会回答

That’s really a good question, but I’m afraid I can’t give you a satisfactory answer about it, because I pay little attention to this, but I could brush up on that and share my immature opinion with you if I may have an opportunity to see you again.

that is not a subject I have explored at length, but I will think about it when I go back home and respond you next time.

I am sorry that I didn’t fully understand your question, could you pose the question in another way?/could you ask me another question?
