No - you'll never see the United Kingdom at the Olympics! Great Britain's team has members from United Kingdom, Jersey, Guernsey, Isle of Man plus all but three of its overseas territories. See here for a fuller explanation.
If it were my quiz (which, of course, it isn't), then I probably would. I did get Great Britain, but as it stands, it feels like a bit of a trick question.
Good question! We're using present-day borders as far as possible. With the ex-Soviet, ex-Yugoslav and ex-Czechoslovak republics, it is impossible to calculate where USSR's, Yugoslavia's and Czechoslovakia's medals would be redistributed into the present day borders, so we haven't tried to. But present-day Germany can easily be calculated because that was a consolidation of two nations into one.
I think combining hides reality. Medals were chalked up to the country or team that existed at the time of the games. Germany post 1990 is not the same as the Germanies from 1968-1988. There was a unified German team for several session of the games. The infamous "unified team of 1992" shouldn't just be dumped into Russia, because it wasn't just Russia. It also included Belarus, the Ukraine, Georgia, Azerbaijan, Armenia, and there rest of the ex-USSR with the exception of the Baltics.
