Quiz Ch. 20

This quiz is based on your reading in Chapter 20 in the textbook.

Like all our quizzes, this is untimed and open-book. You can treat it like a scavenger hunt -- have it open or print it out while you read the chapter. You can exit without submitting the quiz, and come back later. Just  remember that you can only "Submit" once. This is due by 11:59 Saturday. Late submissions will be accepted.
