Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
For a couple of minutes in the quiz, I thought the thumbnail was the plane exporting goods. Then I realized how wrong I was when I typed it in. Good quiz, and fun to take! My suggestion is to organize the states by the money instead of alphabetically.
Hmmmm... should I change the thumbnail or nah. I've been worried that people would confuse it as a cargo plane. Maybe I should change it to a plane being built?
