I just tested your quiz, but I found out by hovering over the answers u can find out whats the right answer or not
It would say #sec_04 by hovering over the right answer or any other number for other questions, and the other 3 faulty answers show "Nay" when hovering over them.
Anyways, to come back to your question, I had the same question a few days ago, how interactions on a webpage can react with a Hype timeline. With some help from Daniel and Jonathan its pretty easy to link any timeline or scene to a javascript function: Able to start a timeline in external onpage Javascript?
