You see sweetie, we all took oaths signed in our own blood. Well, it was somebody’s blood, I think. Anyway, we don’t actually do homework questions. We can help, but research is strictly forbidden. The fact that we were out of our minds on psychedelic drugs when we agreed to it avails us nothing. Twist and turn though we may, every time one of us tries to help someone with homework by telling answers, that person evaporates in a puff of smoke. Sorry. I wonder if the information is located somewhere in your textbook….
