loadVars to create array

I’m rather new at ActionScript and have just discovered --and begun to use-- the LoadVars method.
So far I’m able to load simple data ( like “name”, “address” …) or to create an array of simple items.
I wonder how I can load external data to create an array of multiple choice questions, each of which consisting of [“text of question”,[“choice1”, “choice2”, …], correctChoice]. The questions show one at a time. Something like what I did here:


I’d rather not use XML if possible, as I don’t understand it v well yet.

Any help will be very welcome.
