The speaker claims that what the reading material says has the possibility that the three things are all wrong for the following reasons. First, It is about the size of R. robustus. The reading material says that R. robustus is too small to hunt and eat its prey, such as psittacosaurs or similar dinosaurs. The speaker also must admit that it is too small if R. robustus hunt to eat the full-size psittacosaurs, however, the size of it is enough to do when it comes to hunting to eat the smaller size of the prey than that, like the child of psittacosaurs. Second, it is with regard to the claim that the legs of R. robustus are on the side of it, not the bottom of it. You might assume that it cannot run fast enough to go after its prey if its legs are on the side of its body. However, it is the case that there are animals that have their legs in similar places now and can run much fast. Thus, it is possible that R. robustus could run as fast as them. Finally, it is concerning teeth marks. The reason why there are no teeth marks on the prey that it ate and which it is in its stomach is that R. robustus did not use its teeth when it ate its food. It just swallows its prey without biting or chewing it. In that case, its prey could not have teeth marks on its surface. For the three reasons, the speaker shows that it is possible that all the three claims that the reading material contends are not true. They can have too many flaws to assert that they are true. R. robustus might be not a scavenger.
