I have a question regarding Challenge sets. I would like to be able to
create a list of Challenge sets and then have the user select say 5 of
them that are applicable. The problem with so many challenge questions
are as follows.

Mother's Maiden name? - What if I was adopted or orphaned.
Color of first bike or car? What if I have never owned a car or bike.
Favorite pet's name? - What if I have never had a pet.
What city were you born in? - What if you don't remember.
What is your favorite color? - If you are like me this is a stupid
question and you would just plug in red and forget your answer.

Is it possible to give the user a selection of 15 questions and tell
them to pick 5?
