"Time for your weekly macabre quiz question..."

Each Friday, during my eighth grade history class, the teacher would give us a 10-question, multiple choice quiz on the week's news.  For some reason, nearly every week, there was at least one question about a disaster that resulted in deaths.  Those types of questions would read something like: "Ten people were killed, and five were injured this week in downtown St. Louis.  This was the result of: (A) an automobile crash, (B) a bus accident, (C) a plane crash, or (D) a train derailment."  Back then, I wondered why the teacher fixated on tragedies resulting in death so often.  Now, however, I realize it was probably just that those events allowed him to use the same answer choices every week.
