Paleontologist: The giant pterosaur Quetzalcoatlus had an eleven-meter wingspan and was too heavy to take off merely by flapping its wings, even with a running start. One biomechanics researcher found that Quetzalcoatlus had wings that were far sturdier than it would have needed during flight, and concluded that it took off by using the wings as forelimbs, beginning its flight by leaping with all four "legs." However, this hypothesis is implausible, since Quetzalcoatlus had to attain a speed of at least forty-eight kilometers per hour to take off, which would have been impossible from a standing jump.
Of the following, which, if true, would be the most effective rebuttal the biomechanics researcher could make to the paleontologist'sargument?
A) Quetzalcoatlus could plausibly have taken off by diving off a cliff from its hind limbs, then using the fall to accelerate.
B) Most other pterosaur species are known to have taken off by flapping their wings after a
