The last section in particular is good to dissect as it has some useful features of economic evaluation, so this is a nice one to talk through in class, but I've also made a notes sheet below so you can set this for homework. I think I might set the notes for homework and then look at the langauge and techniques in the lesson afterwards to separate the content from the structure, but I haven't quite decided yet...
