Hmm...an odd thing just happened. I know that I selected the correct answers for this question but then the response was that I'd answered it incorrectly and gave an explanation why one of the answers I didn't select was wrong. Maybe I've finally gone crazy - it had to happen someday.
Great question anyway - Thanks!
