L' Eomot Inversé
Actually, just to create some discord, I think the question is far too easy. And I'm appalled that 23 people out of 1210 got it wrong; but looking at the error rates on some other questions, perhaps I should be surprised that so few got it wrong.
My typical (average) percentage incorrect has been close to 40% - and discussions have gotten hot and heavry.
Sort of figured that I would mend my ways ..... but fear not, that urge will soon disappear .
