The essay questions for the midterm exam.Minimum one page, double spaced page, 12 font per answer. (assignment says atleast one half page if it is single spaced,one full page if double spaced) Each answerneeds documentation from the readings and examples (documentation does not just mean list a book or a website. The reference must apply to a page of the book or a specific place on a website). Note, these are essay questions so each question needs an essay for an answer. Number your answers. I will not search through a long write up for individual answers. Your answers should not be generalizations but should include actual examples.
