I know it should be USA, but I just wanted to specify as some cities are quite hard to guess. And also Chongqing wasn’t on the source listed so it isn’t on this quiz.
Alaska isn't a country; either specify the state for all of the American ones and change the header to "Country/State" or just say United States for them all (I recommend the latter.)
ALTamira.
SiTKa... country (also for Anchorage, Juneau) should be USA.
And Chongqing is missing altogether.
