Citizenship Exam

While home for the holiday I got into a conversation about citizenship with my stepmom-ish. When I worked at BB, a large portion of my employees were immigrants; English was their third, four language. They were from all over the world, from all sorts of circumstances. Amela left Bosnia when the civil war erupted in the late 80s and lived in Germany for several years before moving to the US. She works two jobs, her husband works three and her son is now a senior at Virginia Tech. Roya's father was high up in the local government in Tehran so when the revolution happened in the 80s, she was smuggled out of Iran on the back of a motorcycle in the middle of the night. She was 22. Hortencia was from an affluent family in Peru when her husband's diabetes forced him from his job. Unable to support her husband and sons there, she moved solo to the US. She works three jobs. Muhamad's family fled Iraq during the Gulf War. He was 7 years old. Nooria's family fled Afghanistan during the war with Russia.
Last year, Amela, Nooria and Muhamad finally had the opportunity to become full-fledged citizens. I had the chance to help all three of them study for their citizenship exam, and while asking them questions I realized how many 'natural-born' Americans would fail the test. Not just fail it, BOMB it. It's embarrassing. I'd like to see it required of all Americans in order to be registered to vote, or hold a drivers license. Wonder what that would do for civic attention spans.
Some sample questions, as found on the San Francisco Public Library's webpage:
(1) What are the colors of the flag?
(2) How many stars are on the flag?
(3) What do the stars represent?
(4) When is Independence Day?
(5) Independence from whom?
(6) Who becomes President if the President and Vice President die?
(7) How long is a Senator's term?
(8) Can the Constitution be changed?
(9) If so, what is a change in the Constitution called?
(10) How many amendments are there in the Constitution?
(11) What are the three branches of the US government called?
(12) Who makes laws in the United States?
(13) What is Congress?
(14) What is the purpose of the judicial branch?
(15) What is the Bill of Rights?
(16) Name three rights guaranteed by the Bill of Rights.
(17) In what year was the Constitution written?
(18) Can you name the thirteen original colonies?
(19) Who has the power to declare war?
(20) Which President was the first Commander-in-Chief of the US Military?

There are 100 sample questions (many are repetitive) and most are not difficult; but knowing that most American high school seniors who, while taking Government as a class, would find a way to fail such a test irks me.

(As for the questions above, I got them all right except I could only list 12 colonies. I forgot Jersey.)
