Quick: How many amendments are in the U.S. Constitution?

If you said 27, you’re correct. If you didn’t, don’t worry: Many Americans apparently don’t know the answer.

Before you become a U.S. citizen, you have to pass the naturalization test, where applicants must answer six out of 10 questions correctly. But applicants are allowed to study beforehand. One hundred possible questions are posted online.

The national pass rate is 91 percent as of December 2013, according to the U.S. Citizenship and Immigration Services.

When Xavier University in Ohio polled U.S. citizens by telephone in 2012, only 65 percent got the required six out of 10 questions correct.  Newsweek had a similar poll in 2011, finding almost 40 percent of Americans would fail the test.

Maybe Americans just need to hit the books.

ABC News posted ten random sample questions so you can see if YOU'D pass.  Here they are.

1) What do we call the first 10 amendments to the Constitution?

2) Who is in charge of the executive branch?

3) How many U.S. senators are there?

4) In what month do we vote for president?

5) Who is the chief justice of the United States now?

6) How old do citizens have to be to vote for president?

7) When is the last day you can send in federal income tax forms?

8) What territory did the United States buy from France in 1803?

9) What major event happened on Sept. 11, 2001 in United States?

10) What is the name of the national anthem?

(answers below)

1) The Bill of Rights

2) The President

3) 100

4) November

5) John Roberts

6) 18

7) April 15

8) Louisiana

9) Terrorist attack

10) The Star-Spangled Banner

Some of the questions seem TOO easy....but I gotta admit, I got one wrong (and no I'm not tellin' which one!).  And shouldn't you need to get more than 60% right to pass the test?

How did you do?
