Its simple, think of all the countries in the world, and the sort them in your head by how many times the letter A appears in the country name.
Where multiple countries both have 2 As in their name for example, then you put the countries in alphabetical order.
Official common UN names to be used, e.g "THE Gambia" but not "Republic of the Gambia"
This is great! It would be more challenging if it was a yellow box quiz, because now all we have to do is type any country with an A and it will fill in
-United States
-East Timor
-Ivory Coast
-Cape Verde
