Half credit for #1. The literal translation is wrong but the bottom line is correct.
Zero for #5.
Half credit for picking Brazil over Paraguay on #9.
Half credit for missing Virgin Islands on #10.
I'll give you 83% for missing by a mile on #15. Yeah, I know the question is ambiguous, but life isn't fair.
75% on #18. Only the mysterious envoy extraordinary was out of order.
Zero on #19.
All others correct.
-3.92 points, or 80% correct. Good job!
