One trouble is that on some of the questions, although it was obvious (to the likes of us anyway) which answer was the "correct" one, one or more of the other answers could also be true - e.g. clearly they wanted the answer "television" for the platform running Ceefax, but I also used to use it on my BBC Micro with a teletext adaptor. Likewise the fax machine is usable as a telephone - and mine is also an answering machine.

Additionally, their "correct" answer for using a rotary dial was incomplete - releasing the dial when reaching the finger-stop is also an essential part, given that the dialling happens on the way back. This may seem obvious to you and me, but I was demonstrating my old 'phones to a teenager a while back and had difficulty persuading her to let go of the dial to let it do its work!
