This is Jeopardy

 

I love Jeopardy.  Every year I buy a 365 day Jeopardy calendar and keep count of all the items I get right with the goal of reaching $200,000 a year.  (Sundays, which don't list an amount for the day, I figure are worth $800).  So far this year I have earned $142,000.  

Here are some Jeopardy clues.  Remember, your answer must be in the form of a question.  Answers next week.  Do Not Google to find out the answers.
