Using this week’s assigned readings (and maybe an occasional peak at Google) you should be able to find the answers to your assigned discussion question. You must write one original post for your own assigned discussion question and two replies two other students’ posts. Each post should be at least 100 words in length. For full credit, link to a webpage that pertains to the subject. Have fun!
