Let's say you show up for school and there's a printout of "Abalone! Abalone! Abalone" by Toshio Mori,all ready to be passed out for the class to read. The problem is that you don't have any other materials. A quiz might be nice. One that could be taken online or on a Scantron. That;s easy. Easier than grading 90 papers, anyhow.
