The problem is that, if I get anything wrong, that question immediately disappears and there is no way for me to see it again. I can then start scrolling among the questions and there is no way to recover the information about which question comes before which other question. When all the questions are interconnected, this makes it impossible to answer this quiz.
I'm not saying the question's not valid, I just mean it's incorrectly phrased. It wants something like: "a country linked by rail to another country across a maritime border".
