My report card score was "very bad". I got 7 correct. It said, "Obviously you can't tell them apart." LOL.
To be honest, I wouldn't have even known a couple of the people in those photos were Asian at all.
Now I want to see a test that asks Asians to tell apart different Europeans... lol. :-)
Basically most of us can't. In Hong Kong up until about 1985 if someone speaks English and looks "white" the local HK Chinese wouldn't be able to tell who's who. A German mixed up with American, or a French mixed up with a New Zealander.
Even today most would not be able to tell an Australian from a British - and even some Americans with New England accents will be confused with Poms.
