Some fun for a change: the July 4th test

Especially if you are living in the USA, you are probably aware that it's July 4th.

Even though you're not a citizen of the United States, it is fun to test whether you could be one. There's a test on MSNBC which you can take. I confess I didn't pass it the first time, but on second though the history lessons popped into my mind. How do you score?
