Some Macbeth questions?

I realize this is not the answer you're looking for but I'm going to say it anyway. If you feel that you are being terribly maligned by accusations that you haven't read the play, perhaps rather than asking the community to answer your homework questions, you should ask for clarification on what you don't understand in Macbeth and use that to help you do your homework. Or, god forbid, use google, wikipedia, and freakin' spark notes which will readily give you the answer to your question.
