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 modern crocodiles, even though crocodiles guard their young only for a very brief time after they hatch. Hence, _______.

Summary
Some paleontologists think the fact that fossilized hadrosaur babies and adolescents were found in nests proves that hadrosaurs guarded their young in nests long after the young were hatched from eggs. The author points out that similar nests for young crocodiles are made by modern crocodiles, even though crocodiles do not guard their young for a long time after hatching.

Strongly Supported Conclusions
The discovery of fossilized hadrosaur babies and adolescents in their nests does not prove that hadrosaurs guarded their young in nests long after the young were hatched from eggs.

A
paleontologists who believe that hadrosaurs guarded their young long after the young hatched have no evidence to support this belief
Antisupported. The paleontologists do have evidence. The author’s point is that this evidence does not prove what the paleontologists think it does, but this doesn’t mean the evidence doesn’t exist.
B
we will never be able to know the extent to which hadrosaurs guarded their young
Unsupported. The author criticizes an argument based on particular evidence. It’s possible that we will discover how long hadrosaurs guarded their young based on other evidence.
C
hadrosaurs guarded their young for at most very brief periods after hatching
Unsupported. The author points out that the paleontologists’ evidence doesn’t guarantee that hadrosaurs guarded their young for a long time. This doesn’t imply that hadrosaurs did not guard their young for a long time.
D
it is unclear whether what we learn about hadrosaurs from their fossilized remains tells us anything about other dinosaurs
Unsupported. The author doesn’t criticize the paleontologists’ argument by suggesting that hadrosaurs were different from other dinosaurs.
E
the construction of nests for hatchlings and adolescents is not strong evidence for the paleontologists’ belief
Strongly supported. The author points out that some animals build similar nests, but don’t guard their young for a long time. So, the fact hadrosaurs had nests for their young doesn’t mean they guarded their young for a long time.
