A little history/geography quiz

[killersheep]

hahaha

higher. much higher. guess again

p.s. I was surprised to learn that Indonesia is the 4th most populous country in the world.

120?

Actually, I checked on a couple of different websites, and the answer is 17,508. Yep. It caught me by surprise. I imagine some of them might be kind of small.

I'm thinking some of them must be stepping stone sized.
