I am not certain without checking, but I am fairly sure that they have discovered a few more since 1984. I think they have got up to about 113 by now, and I think they might even have found a bit of no. 127 as well. However, if the question above was in a bog-standard quiz in a magazine or newspaper or whatever, it is probably the "correct" answer even though the question itself is incorrect. Getting inaccurate or out-of-date questions and answers in quizzes is an occupational hazard when the questions are set by people who can't be bothered to do their research properly. That's one of my many pet hates... grrr...
