No. And neither is Turks and Caicos. Probably should say in the instructions that you're including the "non country" countries. Also might want to make this a yellow box quiz. Otherwise people will just type in the T countries without looking at the capital cities.
This was a yellow box quiz for me, but there were no capital cities listed as clues, and the countries weren't in alphabetical order which made no sense at all. I had to just start typing a country and keep moving to another box and typing the same country over and over until it finally fit in a random yellow box.
