There’s a chance that reading this could save your life -- not a very good chance, but you never know. Picture this: one day, you find yourself in the lair of an evil genius called Mr. Evil. In front of you is a pond. It looks calm enough, but when Mr. Evil tosses a fish in, the pond erupts with alligators. Above the pond are two ropes, which Mr. Evil tells you are made with carbon fibers. One is a standard rope of dry carbon fibers. The other is a composite, with carbon fibers glued together with epoxy. The glued fibers seem more like a rod than a rope to you, but you’re not about to argue the point. Mr. Evil tells you that both ropes are the same weight. He is a lot of things -- evil, genius, and a lover of riddles to name a few -- but he is not a liar. Mr. Evil tells you that you will be suspended from one of the ropes, but generously allows you to choose which one. One of the ropes will stretch out and put you within reach of the alligators, the other is stiff enough to keep you safe. Which rope do you choose?
