They say that size doesn't matter. They are lying to you. Size matters. Size is everything.
At least, that is the case with this quiz, where you have to rank the twelve most populous countries of the world in order of their size. Sorry, did I not mention I was talking about 'size' in relation to population demographics? Forgive me, and be ashamed of yourself and your own sordid mind for whatever other grubby implications you were interpreting from that.
Anyway, it is actually rather difficult and took a good few goes to get them all.
