I'm not sure what the maker of this quiz used as reference material. The Kingdom of Norway (so including Svalbard and Jan Mayen and the likes) is altogether bigger than Finland. But just mainland Norway is smaller than Finland. I'm not sure what Norway's rules as what constitutes as "Norway" are. They might have the same ruling for Svalbard as Denmark has for Greenland.
Yeah, the Western Sahara isn't part of Morocco thing isn't gonna happen anytime soon. You can argue it *should*, but might as well accept current reality now that India has withdrawn recognition and the US has recognized full Moroccan sovereignty.

There, Finland is bigger than Norway, but indeed the Kingdom of Norway (including the islands) is bigger, says Wikipedia). Always tricky this...
Also, am I being a real thicky, or should Canada not be on the list? Are you thinking of St Pierre & Miquelon or something?
