Question ID:PT74 S4 Q10 Passage:In 2005, paleontologist Mary Schweitzer made headlines when she reported finding preserved soft tissue in the bones of a Tyrannosaurus rex dinosaur. Analysis of the collagen proteins from the T. rex showed them to be similar to the collagen proteins in modern-day chickens. Schweitzer's discovery therefore adds to the mountain of evidence that dinosaurs are closely related to birds. Stem:The answer to which one of the following questions would be most useful to know in order to evaluate the argument? Correct Answer Choice:CChoice A:How rare is it to find preserved soft tissue in the bones of a dinosaur? Choice B:Is there any evidence at all against the claim that dinosaurs are closely related to birds? Choice C:How likely is it for animals that are not closely related to each other to have similar collagen proteins? Choice D:Is it possible that T. rex is more closely related to modern-day chickens than to certain other types of dinosaurs? Choice E:Before Schweitzer's discovery, did researchers suppose that the collagen proteins in T. rex and chickens might be similar?
