Ministers of several states within Germany tried to push for a naturalization test that would be given to any foreigner applying for German citizenship.  The tests would have included questions in history, values and language.  When I looked at some of the proposed test questions, I wasn’t sure if I could answer all of them correctly. They finally agreed upon classes for new immigrants. I think that those courses are a much better solution as proposed tests that ask for the name of the person who discovered the TB virus and the like.
