Questions on Readings:  Most lectures will be accompanied by one or
more readings, which I expect you to read before you come to class. To
help you focus your thoughts on the main points of the reading I will
assign one or two questions to be answered for each of the reading
assignments. Each question should be addressed in less than a page, due
at the beginning of the class for which it is assigned.  Turn in a hard
copy of your solution at the beginning of class. Each of these will be
graded on an OK/not-OK basis.
