Oh, I'd fully expect most people not to be able to explain the details but you'd think most would know it was involved with the environment, especially since an early question gave the same four answers re: public option, which really should have helped a little to boost performance, I would have thought. Considering that the peak of the curve was just a hair higher than flat random answers should have given, it's a bit disappointing, and I'd say anyone who didn't get half or more should probably make a point of not voting - but everyone did much better on the science quiz from same, so that cheered me a bit.
