Question ID:PT92 S1 Q5 Passage:Of the dinosaurs of the birdlike group called ornithomimids, the later ones had toothless beaks and weak jaw muscles. A fossil of the later ornithomimid species Gallimimus bullatus was found to have remnants of a comblike plate inside the beak. Such plates are found in modern ducks and geese, animals that strain small bits of food from water and mud. Paleontologists therefore hypothesize that G. bullatus fed by filtering food from water and mud. Stem:Which one of the following, if true, most bolsters the support for the paleontologists' hypothesis? Correct Answer Choice:DChoice A:Some dinosaurs with toothless beaks and weak jaw muscles are believed to have pursued small prey and to have eaten eggs. Choice B:Toothless beaks and weak jaw muscles were not common to any dinosaur group other than ornithomimids. Choice C:Except for the comblike plates in their beaks, G. bullatus shared few anatomical features with modern ducks and geese. Choice D:Most G. bullatus fossils have been found in sediments deposited in lakes, rivers, and other wet environments. Choice E:Paleontologists have not found evidence that any dinosaurs other than G. bullatus had comblike plates.
