Some paleontologists believe that certain species of dinosaurs guarded their young in protective nests long after the young hatched. As evidence, they cite the discovery of fossilized hadrosaur babies and adolescents in carefully designed nests. But similar nests for hatchlings and adolescents are constructed by modem crocodiles, even though crocodiles guard their young only for a very brief time after they hatch.
Hence, \(\underline{\hspace{2.5cm}}\).
Which one of the following most logically completes
the argument?
A) paleontologists who believe that hadrosaurs
guarded their young long after the young
hatched have no evidence to support this belief
B) we wi1lnever be able to know the extent to
which hadrosaurs guarded their young
C) hadrosaurs guarded their young for at most very
brief periods after hatching
D) it is unclear whether what we learn about
hadrosaurs from their fossilized remains tells
us anything about other dinosaurs
E) the construction of nests for hatchlings and
adolescents is not strong evidence for the
paleontologists' belief
