I've not seen it either, but from hearing / seeing stuff about it, I knew the answer, I know "winter is coming", John Snow, dragons and a woman who's good with them but I couldn't spell her name, Stark, and that the character played by Sean Bean dies, because that's what he does.
I raid the first question as what is the capital of Australia, and I was very confused when I tried Canberra, and it didn't work. Then when I failed the quiz, I saw the answer was Vienna. Then I felt really stupid.
Know nothing about Game of Thrones, but seems that parts are unavoidable in the culture and in some of the other quizzes here, so somehow knew that name. And the women's name/river answer, it's actually a fairly common men's name as well.
Stupid spelling of perennial... first neatly tried perannual, but allready felt that might not be it, but hey some accents really butcher pronunciation and what is written is not at all what is said. Though I was fairly certain it sounded there was an i in it, so tried perannial... nope... then gave up, figured it must be something different completely. Because logically the -ann_ must stay in there because it is the root for year. guess again.. sigh.
