In the reading passages there is ample support for the author's claim that Lambeosaurus's special physical feature may have played in a specific way. However, the professor in the lecture gives several reasons as a rebuttal to the author's points.
First, the professor in the lecture contends that the crests were not used to attract the female to mate. They would have used the sound and some behavior to mate, instead of using of the crests. As like the other animals have done. Also, the Lambeosaurus was unlikely to mate with female dinosaurs. This casts doubt on the reading passage's claim that the crests would work as a role to attract the female due to the fact that it was changed follow sex and age. (무슨 말인지 잘 모르겠어요)
Next, the professor in the lecture insists that the crests could not be used as combat. Actually, the crests are located on the backward of the head, which means that it would not be (be동사 필요합니다) a weapon for a fight. Also, inside of the crests is hollow, thus it means that it could be fragile without enough power. This counters the reading passage's suggestion that the crests would work as a role to combat and be used for a fight.
Finally, the professor in the lecture argues that the crests do (주어 동사 불일치) not provide the air. The crests are hollow so they are able to contain the air, however, it is not enough to breathe well under the water. The size of the crests is too small to provide all parts of the body. Also, if it were possible to breathe under the water, it will be just a few seconds. This counters the reading passage's assertion that the crests would work as a role to breathe them under the water where the food is placed.
