This quiz could certainly use a lot of improvements. I found the level of the questions alright and it was nice that you sometimes asked to connect and arrange things (that's not something you often see in quiz games). However, only seven questions in all is way too few in my opinion. It shouldn't take that much effort to add a lot more questions with a similar set-up. Basically all you have to do is rewrite the questions and answer and rearrange the code a little.
Furthermore, the connecting question was quite annoying since it was difficult to get the pieces in the right place. The screen would scroll up and down rather quickly so that I had to move my mouse the other way again to the answer I wanted to pick. Also, the pieces switched places when I didn't want them to. I would say, try to get rid of the scroll bar and get everything within one frame.
Lastly, you could work a bit on the lay-out. Right now I can't help but assume you used some pre-made sheet and just filled in the questions and answers.
Overall 2 out of 5. I think the questions you asked were nice and challenging, but it needs a lot of improvements in other areas.
