Calling All Harry Potter Fans

I've been thinking about sentence structure lately, and came across this tough quiz from Academic English Cafe. Writer Beware! This quiz is not for WEENIES. You have to answer a question about simple, compound, complex, or compound-complex sentences, and what makes it interesting (but not any easier) is that every sentence has to do with Harry Potter.
Confession time: I got THREE wrong. Yikes. Time to go back to school.
