Duckbill dinosaurs, like today's monitor lizards had particularly long tails, which they could whip at considerable speed. Monitor lizards use their tails to strike predators. However, although duckbill tails were otherwise very similar to those of monitor lizards, the duckbill`s tailbones were proportionately much thinner and thus more delicate. Moreover, to ward off their proportionately much larger predators, duckbills would have had to whip their tails considerably faster than monitor lizards do. The information given, if accurate, provides the strongest support for which of the following hypotheses?

【选项】If duckbills whipped their tails faster than monitor lizards do, the duckbills tail would have been effective at warding off the duckbills fiercest predators.
