In this set of materials, the reading passage explores the impossibility of Pterosaurs' capability of powered flight, and the professor's lecture deals with the same topic. However, she casts doubts on these arguments, and in the lecture, she provides three specific points to substantiate her opinion.
To begin with, although the reading passage suggests that Pterosaurs have slow metabolism since they were likely cold-blooded, the professor argues in the lecture that Pterosaurs were warm-blooded animals rather than cold-blooded animals. This is because according to the fossil record, their body were covered with fur-like hairs, which were used for maintaining body temperature, and this indicates that they were warm-blooded animals with sufficient energy for flying.
Moreover, despite the statement in the reading that Pterosaurs were too heavy to have the ability to fly, the professor contends that their bones were in fact hollow and light. She supports this point with the fact that the hollow bones allow them to flap wings fast enough to fly in the air. Clearly, professor's argument refutes its counterpart in the reading passage.
Finally, the author of the reading claims that the back leg muscles of Pterosaurs were too weak to be used for launching themselves into the air, whereas the professor asserts that Pterosaurs were different from birds which used two limps for running and jumping in order to gain speed for launching into the air. Then she explains that this claim is indefensible by pointing out that Pterosaurs actually used four legs instead of two limps; as a result, using four legs enable them jump high enough off the ground so that they could fly.
