Be sure to cite your sources, use APA style as required, check your spelling. Do not just answer the questions. You should be able to explain the logic behind your answer and point to a credible source to support your position, even if it is just the textbook.  You are expected to spend at least 6 hours studying the questions, finding and studying good sources, and understanding the nature of the answers and at least an additional 6 hours answering these questions and polishing your writing, so the answers are compelling.   Invest your time wisely, giving more time to the complex answers in order to ensure that you demonstrate that you truly understand the answer. Answer questions in 350 to 400 words each question using 5 credible references.
