See how good you are at picking out the Chinese, Korean, and Japanese people by the pictures.
It's tough, as a few have dyed hair, they all have weird expressions on their faces, etc. It's much easier to judge someone who's natural - i.e. with a blank or mild expression and no weirdnesses done to their hair.
I got an 11. :/ On the other hand, I can honestly say that at least 4 of the 7 I got wrong I was dithering between two choices and my other choice was the right one. The average is a 7, which considering the law of averages sounds about right. (3 choices per pic, 18 pics, means 6 should be the average.)
