what does "question authority" mean in the following passage? (I put question authority in brackets)
Well, I guess I am a lifelong troublemaker and when my parents taught my twin brother and I to "question authority", I don't think they knew where it might lead. (Laughter) And, they probably really regretted it during my stroppy teenage years when, predictably, I questioned their authority a lot. And a lot of my school teachers didn't appreciate it much either. You see, since the age of about five I've always asked the question, but why?
