The passage doubts that pterosaurs can fly by flapping their wings by proposing three arguments. Unfortunately, all of these arguments are contradicted by the lecture.
Firstly, the lecturer argues that pterosaurs are capable of energy supply. In the article, pterosaurs are assumed to be cool-blooded reptiles whose low metabolism is unable to produce enough energy, whereas the lecture rejects this idea by pointing out that their dense-hair-like covering implies that they are warm-blooded, revealing that they possess a high metabolism, therefore they can generate sufficient energy.
Secondly, the speaker asserts that pterosaurs are able to keep airborne. As shown in the passage, a pterosaur is as large as a giraffe so that it is not allowed to flap its wings fast. Conversely, the lecture introduces the fact that the weight reduced by its hollow bones are indeed light enough to enable it to stay aloft.
Thirdly, the lecture opposes the passage's view that its minute hind leg muscles are incapable of running fast to take off the ground by contending that unlike birds who launch by using two back legs, pterosaurs use four strong limbs to push from the ground in order to launch into the air.
In short, all the assumptions made by the passage are refuted by the specific reasons in the lecture, which suggests that these reptiles are likely to be powered-flight animals.
