"Anxious to avoid accusations of selling filth to minors, Sierra came up with the clever idea of a trivia quiz using questions stemming from the 1970s and earlier to make the player “prove” that she really was as old as she said she was. Some of the questions are decidedly obscure, to such an extent that they create quite a challenge to those of us today who are well over the the age of eighteen, but, what with almost thirty years having gone by, aren’t quite up to scratch on our Baby Boomer trivia. Thankfully we have a secret weapon in Wikipedia."
Or, if I remember correctly, you could just use alt+x to skip the quiz :) Played this a lot as an 8 year old kid.
