I just saw this too. You can also take an online test like the one they gave to Americans in the survey and see how well you do as well as seeing the results of each question. Some answers are just scary.
Indeed. I got 19 of the 20 questions right, i got only the question "What percentage of Population growth in the US was due to immigration ?" wrong. I said 52% or something, but it was like 30%.
Others were simple, like "on which continent is the Amazonas rain forest"...
Yeah the immigration question was the only one I had to guess on, I did guess correctly though. The people who said Sudan was in Europe must have some problems.
