citizen, know thy country

How well would you do on a citizenship test? No cheating, now! Google is not allowed.

When immigrants want to become Americans, they must take a civics test as part of their naturalization interview before a Citizenship and Immigration Services (INS) officer. The questions are usually selected from a list of 100 sample questions that prospective citizens can look at ahead of the interview (though the examiner is not limited to those questions). Some are easy, some are not. We have picked some of the more difficult ones.
