Body1 没有考虑他因,他因就是听到的内容
First, the evidence of dinosaurs fossils found in polar region cannot prove that the dinosaurs are endotherms as the passage indicates.
The passage fails to take alternatives, such as temperature, migration and hibernation, into account. That is, the polar region is much warmer than today. Even in cold winter, polar dinosaurs can migrate to warmer places or hibernate like modern animals. In other words, non-endoterms can survive in polar region. This directly contradicts what the passage indicates.
Body2. 错误归因
Second, the connection, concluded in the passage, between dinosaurs and the position and movement of legs is inaccurate. The speaker says that growing to ver large size can bring advantages to dinosaurs. As a result, dinosaurs get more weight and the dinosaurs have their legs placed underneath bodies in order to support more weight rather than running as the passage mentioned.
