A few years ago mine was quite bizarre.
They asked about AM/FM but I listened to stuff at the time via DAB... And then there was shortwave which I listened to regularly...
On top of that some great tropo happened and I listened to that too...
Luckily there wasn't any sporadic-E. That would have done it in completely. :-)
The concept wasn't the problem, but wow, was it narrow in dealing with technology.
It was followed by this gigantic survey on shopping, living etc....
