Good quiz. I have a couple of suggestions for improvement. Qn 8 should refer to the island - presumably Grande Comore? - not Comoros, which is an archipelago. Same issue with Qn 13 - there is no such island as Svalbard - Longyearbyen is on Spitsbergen. Incidentally, Ny Alesund is further north but I guess that you don´t count it as a settlement since it is now a research station.
