Something i've learned about polls and quizes is that
how a question is asked can sometimes distort the answer. Your quiz seems to be fine in this respect, but i have at times seen questions on polls like so:
"Is Bush stupid or just naive?"Well obviously this is a leading question with an embedded negativity, but sometimes questions are phrased more subtly and it's difficult to see how they distort. Often on polls i have had no options for answers that reflect my views and have consequently chosen answers that don't quite fit. I'm not saying i like Bush, by the way, i'm just using this to illustrate how polls and surveys can distort the response. Sometimes we can be misled into thinking most people think one way or another, because of the way the questions were asked.
This can happen on a very personal level, too. We might be asking ourselves every day, "What's wrong with me?" That question also has an embedded negative assumption. In my own life i
do like asking questions with assumptions, but i like making them positive, like, "what am i looking forward to today?" (assumes there are things to look forward to). "When will i find and be with my true love?"... assumes that i will find someone for me. And i think these kinds of questions helps to make those things come true in a very real way. They shift our focus to where we wish to go and how to get there.

How about if i start a quiz and ask:
1. Do you think i am:
O --- smart.
O --- really smart.
O --- REALLY, REALLY SMART.
O --- Einstein smart!!!!!!!!!!

2. Do you like me:
O --- A LOT!
O --- Very much.
O --- Can't get enough of me!
O --- I want to be the president of your fan club!

3. Am i:
O --- Funny.
O --- So funny you're rolling on the floor.
O --- Please stop! I'm laughing so hard i can't breathe!
