Name the national bird of a country, and that country will light up on the map. Some countries don't have a national bird. For national birds that have a long name, it can be shortened to the basic name of the bird. For example, if the national bird was a peregrine falcon, you could type falcon and it would work. This quiz took longer than you'd think to make. Not to mention, I copied this quiz (you should check it out by the way) so that I didn't have to deal with all the svg stuff. Enjoy :)
You can fix it via the 'edit styles' menu on the 'design grid' page in the quiz editor. Just change the total width from the default 730 pixels to 830.
