freeztar Posted September 12, 2007 Report Share Posted September 12, 2007 People are not responding because you are obviously trying to get answers for homework or a quiz. It would be better for you to post what you think the answers are and why. Then people will be more willing to help you understand the problems. :phones: Quote Link to comment Share on other sites More sharing options...
