The response to each of the following questions should include in-text citations where appropriate and complete references in APA format (for each and every question). Please take a graduate-level, well thought-out approach to your responses. Surface-level answers will NOT receive full credit.

Do NOT respond to each question with one large paragraph.

You should type your responses to each question immediately below the question or when there are letters, such as A, B, etc. then you should type your response immediately below that part of the question using the regular black font and Times New Roman 12. Also, immediately below your answer to EACH numbered question you are to list all references you used to answer that question.Therefore, there should be four sets of references – one set for each question.

Any deviation from the above instructions will result in an additional loss of points.

Each of the four questions are valued at 25 points.
