French Guiana, Réunion, and Canary Islands are each legally full, integral parts of their respective countries, and are not territories in any sense other than that they are some distance from the larger part of their country. This is essentially no different than Alaska or Hawaii is in the US.
nice quiz. It would be even nicer (and harder) if you restricted the answer to a specific box - otherwise by typing e.g. UK, all boxes get filled in straight away.
I would also rename the quiz and avoid the 'territory' word, as not all of these islands are territories strictly speaking.
