I really think you need to state in the description that country names can be more than one word. I feel that it currently implies that it should be one word only. You should change this for all of these similar quizzes.
We just had a careful look-over of the instructions and we cannot detect anything that implies the answers only come from one-word countries. What makes you think otherwise?
