A few suggestions. The main one is, have you not arranged this quiz the wrong way round? The title suggests that we have to give the owner of the territories, yet you give us the owners and expect us to guess the territories. And some of those territories are not spelled correctly - e.g Cocos & Keeling islands (which seems to have sprouted some brackets!), Faroe islands, St Martin and Montserrat.
when making the quiz I realized that if it did give the owner as the answer it would answer it for all of the others. for example, if you typed in France all the France answers would appear. And for the misspellings, I copy most of these from a random website and I guess they had it wrong but I will fix it.
