Yeshiva graduate challenge

Here's a quiz I found at blogthings. It's called, "Could you pass 8th grade science?" I have a feeling that the average chassidish yeshiva high school graduate would get at least half the questions wrong. Am I an interminable pessimist? Probably... but let's just say that listening to most bochurim discuss issues in Torah & science makes it obvious that they haven't the first clue about the fundamentals of physical science. But take the quiz and prove me wrong. Answers in the first comment. No cheating!
