Here's a new one: Arduino Quiz #n: History and Politics
I, um, might have had a bit of fun with this one, and I recommend not drinking any liquids while taking the quiz...
(I did try to stay away from questions that were TOO opinion-based.)
(But ... who knew that Arduino had had quite that many crises!)
Hmmph. One of the for-pay features at proprofs is apparently the "feedback per choice" (as opposed to "feedback per question.") Rats. I liked that one.
