A question from Giorgos to Rui, who passed it on to me, which I now
answer for everyone's benefit: Answer Problem 4 in Problem Set 6 in any
way you can. We will give you credit for a correct answer, and we will
give you extra credit for staying as close as possible to the
definitions on pages 21, 22, and 23, in Handout 09.
