If anyone is wondering, here is why the False ones are false. About 60% of the world's people live in Asia, Peru is about twice the size of Texas, Borneo is the only island with three different countries, Russia is only 2 miles from Alaska, Portugal is too far north for this to happen, China only has one time zone, Reykjavik is not far enough North to go completely dark in winter, at the south pole the Aurora Borealis is called the Aurora Australis, a person from Moscow is called a Muscovite, there are no places where four countries meet, South Africa's flag has 6 colors.
Great quiz - I only managed 12 despite total guessing being worth 10! The Peru-to-Myanmar question is not always true though - from the western side of Peru to the eastern side of Myanmar, the shortest distance is actually westwards.
Tricky quiz. Very proud of myself for seeing through the traps to get 19/20. I need to add another feature that will allow explanatory text to appear post-quiz.
