Country Transits: Further Away within the Same Continent
In each continent, which two countries require crossing the most land borders to go from one to the other?
CTD is Country Transits Distance: number of land borders you have to cross to reach a country (moving between different parts of the same country, eg going from France to French Guiana to St Martin does not count as a move)
I think you don't have to cross any border to go from Greece to Ireland -by boat. If Ireland is answer, why not Iceland? And how about Cyprus in Asia? Sorry if I don't get the rules right, I'm not English speaker.
Hi, thanks for your comment. I don't know if it's a reasonable choice but from Ireland you can cross a land border to reach the UK. Then you can 'fly' to Gibraltar and from there cross the border to Spain, from Spain you go all the way to Greece. I tried explaining this in the notes (see 'CTD is Country Transits Distance...'). So in these quizzes I do consider Spain-Marocco borders (Ceuta) and similar ones
I don't know if it counts as an answer but you can go from France to the UK, by for example train, by a tunnel under the sea. The same way you can go from Saudi Arabia to Bahrain.
In these quizzes you need to cross a 'land border' so under/over the sea. What you're saying certainly makes sense (similarly you could have Malaysia-Singapore) but the data I have (taken from wikipedia) lists as land borders Morocco-Spain (and similar ones) but not UK-France
