It's PROBABLY too squicky to include on the exam — I will defer to the lead instructor on this — but it was just too damn entertaining to write. It concerns the Lotka-Volterra competition equations I was going on about a week ago and whether or not zombies will competitively exclude cannibals, cannibals will exclude zombies, OR they will coexist (the premise of the question is that zombies and cannibals are both competing for the limited resource of human flesh).

ETA: I'm not going to include the exact question or answer here, on the off chance that one of my students posts here and then we include it, but I would love to hear speculation not based on the math on who would win. I always wonder about scenarios like this!
