Easily automatable
My gripe with this is that you could easily actionscript the whole thing and then just have to update the text. Look up some tutorials on how to control TextFields with script, then add logic to test which answer is correct.
If you do it this way, you could come up with a game with hundreds of questions with no more additional effort than looking up new text.
Also fix those buttons - add a hit area behind them so it will work if you click anywhere inside a letter (e.g. inside an "o").
