text: Really, you should do your own homework. These are excellent questions your teacher has set you.\n\nThey are not the usual boring "look it up in the textbook" type questions but are actually interesting and designed to get you to think and understand reather than regurgitating.\n\nAnd how do you repay the effort taken to make the subject interesting? You cheat and ask strangers to give you answers ot regurtitate.\n\nVery disappointing.\n\nThere are no dumb quetsions, but there are certainly dumb questioners with even dumber motivations for questions.
