Our Daily Bleg: Book-Club Questions Needed

A reader named Jacquilynne Schlesier writes:

My book club is reading Freakonomics as our selection of the month and we’re meeting on Wednesday. It’s my selection, so I’m responsible for bringing 10 questions that’ll prompt discussion about the book.
Based on the argument that broke out at our last meeting when I merely mentioned the idea behind the abortion/crime bits of the book, I don’t imagine I will actually need 10 questions to keep the discussion moving for two hours (more likely, I will need a very large whip to keep the members from maiming each other), but still, I figured it couldn’t hurt to ask the readers of Freakonomics if they have any discussion questions they’d use to prompt conversation about the book.
