Yes, it becomes obvious when looking at the India-Bhutan border that is lighter than the other borders, because there is no second connector border on that one; in other words, rather than drawing a squiggly Bhutan, QM drew the India part of the border and placed a rectangular shape underneath of it, forming its shape.
Great quiz, really enjoyed it and for jetpunkers like me that prefer to do the thinking without the push of the time limit, I am glad that the opportunity to stop the clock is available.
