Interesting quiz. It would be helpful if you could explain in the description how answers need to be formatted (as in "Liechtenstein and Austria" didn't work, but Liechtenstein-Austria did).
How long is the Liechtenstein-Switzerland border? - I thought it was about 15km, but maybe not. I don't know how long the San Marino-Italy border is in total, but perhaps that should make this list too?
Surely those two borders should replace the two longest in this quiz that are both over 100km ...also Gibraltar isnt a country its an overseas territory
