9 questions out of 22 about Europe and 7 about the US, 2 of which are pretty obscure if you aren't American - Reno and Ohio. I'm not sure why you feel this is "Euro-Centric"
There's an arch built over a street in downtown Reno, and someone submitted that slogan as the winning entry in a contest to come up with a city slogan to be painted on the arch. (It makes one wonder what the losing slogans were.)
Yes. In fact, while "Gaul" (in French "Gaule") is the usual translation of the Latin word "Gallia", the two are actually etymologically unrelated: the former comes from a Germanic root that referred to 'foreign' (eg non germanic) people, and also gave words like Wales and Wallachia. I think the hint ought to be changed a bit.
I'm surprised so many people got Koln! The only reason I know that is because I took German in college. Did 57% of people take German in college, or are they just smarter than me?
By the way, the reason I marked this comment: the Reno question is, in my opinion, very bad and should be replaced. Or at least, the hint should be changed to something that is not a tourist slogan.
(Then tried "Jeri" to stick to 4 letters. Oh, ignorance, you are delicious.)
As long as it is questions people outside of the US (or whatever country the question is about) have a chance of getting it is fine.
