As a serial display of the blocks after the response from the user?

I have a problem such that if I click on the user and if he did not respond, he move on to the next question, but that it was impossible to move the user without answering the question so I'm not caught up. Need to array or json to do test or not so I thought?
Here's my example https://jsfiddle.net/hollanditkzn/ogs7zf7z/
This is the view after the database derive all the questions.
If You are not one radio say that the user moves and the next question, and you need to he couldn't move
