Questão 94 da prova cinza do segundo dia do Enem 2014 Segunda Aplicação

I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. Humans came in with a rather unimpressive
showing about a third of the way down the list … That didn’t look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle. And a man on a bicycle blew the condor away. That’s what a computer is to me: the computer is the most remarkable tool that we’ve ever come up with. It’s the equivalent of a bicycle for our minds.
