Did they change the quiz? You quote there as being 8 questions.
I was fairly wrong about the LGPL.
But I am irritated about the GPL question they missed. I think that their interpretation of section 3b of the GPL reflects neither common usage nor intent. OK, the wording of ...on a medium customarily used for software interchange... suggests a physical item with code on that, but s/on/in/ and you get the common understanding - the Internet is widely used for software interchange, and this is the first time that I have heard anyone claim that posting code on the web isn't enough.
If their interpretation is true (and looking at the source, they probably had good advice), then that is something that I hope gets fixed in the next version of the GPL. :-(
Cheers,
Ben
