Yes, how do you think we should deal with nervousness when we are presenting?

Good question. I think we can assume that in the early stages we feel most nervous

it's best to be ready for this. If you've done your preparation well, I think it's

just a question of rehearsing before the presentation, may be with a friend, who can give you some

feedback. (Does) that answer your question?

Yes, thank you.

Would anyone else like to raise another question?

I was wondering what we can do if we get a hard question or a question we can't answer.

Right. Important point. First, give yourself a little time to think, by saying , for example

Yes, that's an interesting question, or, I don't think there's any easy answer

If you have the information somewhere else you could say I don't have the details

at hand right now, but if you leave me a contact address I'll get back to you as soon as I can.

Yes, I think so. And sometimes you could try in general terms to answer the question, but

say you need to find fuller details later. Have we answered your question?

That's fine yes, thanks.
