9 out of 10. *blink* Wonder which one I got wrong, they don't say.

The Washington Post once printed the entire list of questions from which they draw the real quiz. Took a whole page, although it was fairly redundant - you have your choice of "When does America celebrate its independence" and "What does July 4 mean in America" for example.
Yeah, the local paper usually posts the citizenship test around the 4th of July ;)
