Answer each of the 21 questions as specified (2 from each chapter within Modules 5 and 6). Answer each question completely, yet concisely. Note: this written “test” is not just a completion assignment, but will be graded accordingly for accuracy and completeness of your answers. Note: words like “explain”, “define”, “describe”, and “summarize” require some explanation versus the word “list”. Read each question carefully so you know what it is I am asking you to write. You will need to spend ample time working on this assignment. Do not wait until the last minute! This assignment is due by 11:59pm Thursday, April 30.
You may research these questions using various sources, but be aware of plagiarism. Any direct quotes from sources must be referenced and cited, just like any research paper, and the extent of direct quoting needs to be limited. Your best source of information is your textbook, as the information and questions directly address topics covered for this course, and from the textbook. You must do your own work, no copying from anyone else. You will submit this assignment to a drop box, just like your out of class assignments, and SafeAssign will be enabled to check for plagiarism and copying.
