For this country elimination, you have to name ALL of the countries that follow the listed category and all of the categories before that (IMPORTANT: if the country makes it to the second section, when you list the country, put the number of the section after it with no space, for example Peru3 or Kazakhstan2, I had to do this cause it was impossible for me to have it so that when you list a country, it does not fill out the country for all the categories that it is in, this may sound confusing, but you'll see what I mean when you take the quiz!
In theory it is a nice idea, but since you can see the answers as soon as you filled the first category you can take the answers for the other categories from that. It becomes typing with very little thinking from that point on :/
