Side Note: When answering these questions, I want the tutor that answer it to use his own words and resources. I don't want something that has already been done from last year or sometime this year. I also need references and paragraphs cited that need to be cited. Thank you. I paid 8 dollars for this i would expect to get an original answer. I understand people had asked these same questions already this year, last year and years past. Thanks for taking the time to read this.
