Some interesting choices of great men. Couple of issues.... two of the questions appear to be missing (not that I'd have known them anyway judging by the answers) and I'm quite confident that Beethoven was German. He was certainly born in Germany anyway!
These are just some people I personally admire (-: I think the two missing questions you mean are the ones that come under the question where there are three answers (the three Ukrainians). I'm not sure if I'm just being thick but it seems the 'merge cell' button in the quiz editor has disappeared. And as for Beethoven I meant to put German/Austrian, since he was indeed born in Germany but lived in Austria most of his life and accomplished his great works there. But then of course in those days the map of Germany was a huge confusing mess compared to today :-)
