When immigrants want to become Americans, they must take a civics test as part of their naturalization interview before an immigration officer. Could you pass it?

The questions asked by the U.S. Citizenship and Immigration Services (USCIS) 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.

NOTES: Candidates are not given multiple choices in the naturalization interview -- which is conducted orally -- and are expected to respond with complete answers. The following questions have been adapted from the sample USCIS questions. The originals can be found here.
