Can you list all Country Borders of the World, starting from the shortest? Type the names of the two countries one after the other.
Under L you are shown the length of the border in km, under B the number of neighbours the two countries have. At the end of each answer you are shown the initial letters of the next pair of countries.
Since the first one is a dubious one, you are shown the first answer
Note that each bordering pair is considered once even if the border is split in many segments
