When I was a kid, I learned from my 5th grader schoolmates that you can bypass the questions in LSL1 by pressing Alt+X in the original AGI EGA version. I think they've changed it to Ctrl+Alt+X for the VGA remake.

But you haven't mentioned which game you're talking about anyway, I just felt the need to share this detail of my dirty childhood. :)

There's a cheat sheet called "Answers Sheet" in the original game's installation directory. There should be a shortcut to it in your Start menu (and somewhere in Galaxy, too). :)
Not sure about any of the sequels/remakes. Then again, I'm not sure how many of them actually had that kind of copy protection.
