1) A: Transfiguration
2) C: Drive somewhere....
3) A: Follow the directions exactly
4) C: Try to remember
5) So, I'm assuming because of the way you phrased answer D for this question that I'm not alone when I come upon the sleeping troll, in which case I would D: Retreat & protect my friends. But if I were alone, I would B: Work out my escape (most likely by utilizing A: Try to confuse him)
6) D: Tell the Professor I lost it, hoping for the best.....I guess....I don't think I'd tell him where I lost it though....
7) A: Learning....being a wizard
8) C: Retrace my steps....find it
9) C: ok, so while I would definitely ignore the Head's mandate to go to the Common Room, I wouldn't just simply sprint past him either - I would ask what's up. After all, a fellow student shouldn't just be barking orders at me, this isn't the military & I'm not a dog....even when I transfigure myself into one...hehe
10) C: Turn them into a toad (or whatever fauna suited them well)
11) C: Transfiguration (even is this answer falls in the D-slot)
Sorry I couldn't just pick from the available choices - I tried to explain myself as well as I could above....do I still get to get sorted?
