1. Unit 3 Quiz
This is a short answer quiz designed to give some indication of the depth of coverage you may expect to encounter on
the upcoming final exam. It will help you study for the exam. Most of the questions correspond to the multiple choice
questions on the final, so the answers are at most a couple lines long. For the true/false questions first indicate the
answer, then indicate why the statement is true or false. Unlike the previous quizzes, this quiz is much more
graphical in nature. Most of the answers will involve labeling things correctly and perhaps elaborating on their
functions. Keep your answers concise, in some cases a few words will suffice. The questions are all worth one point
each. Your answers are to be typed. Handwritten submissions will not be accepted. See the essay formatting
guidelines for typing instructions. However, last minute, hand written, amendments to your answers are acceptable.
And remember to identify the assignment and put your name on it.
