Isn't Mesopotamia is just the old name of Iraq. I thought it was Fertile Crescent. And where is Ha Long bay, I have never even heard of. You might can add Himalayas or the Bay of Bengal. Great quiz though.
No, the Fertile Crescent would be much larger, it would extend all the way down to Israel whereas Mesopotamia only covers the region between Tigris and Euphrates. Ha Long Bay is the most iconic landmark in Vietnam, a great country! These quizzes aren‘t supposed to easily get 100%, but they should show the variety of landmarks all over the Asian continent.
