You must compose detailed and well described answers to the following questions. This can not usually be done in a few words but instead it may take a paragraph or more. Number all of your answers so that I can follow your homework. You must save your homework as either a Word (.doc) or a Rich Text Format (.RTF) file. If you do not remember how to do this refer back to the handout in the orientation learning unit.

• You must be thorough (a few words or a couple of sentences will not do)
• You must answer all that has been asked
• If it says compare and contrast to talk about all of the similarities and then all of the differences
• If it asks for two differences be sure you include the two difference for each item being discussed
• Number all of your answers - other wise I have no idea what you are answering
• Neatness is important (use formatting of some sort)
• Leave at least one blank line between answers so that the white space separates your answers
