TPO 53 Task 1

text-align: justify;">The reading passage and the lecture are both about the evidences to affirm whether dinosaurs were endotherm animals. However, it can be stated from their contexts, that the lecture brings into question the points in the reading passage. The author of the text claims that the dinosaurs were endotherm animals. The lecturer completely refutes the arguments in the article, hence, arguing that the explanations to support this idea are faulty.

text-align: justify;">

text-align: justify;">Firstly, it is stated by the lecturer that although some dinosaurs have lived in polar areas, these areas were not too cold as today. Besides, the dinosaurs were able to migrate from these areas during the periods of inclement weather or they could hibernate to survive. this idea directly contradicts the reading passage’s claim that the fact that dinosaurs have lived in polar areas prove that they were endotherm animals.

text-align: justify;">Secondly, the lecturer asserts that the purpose of the position of dinosaurs’ legs in the underneath part of their body is to support heavy weight. this body structure configuration is an advantage for them, but not gives them more energy for running. this idea strongly contrasts with the article that mentions that the fact that dinosaurs’ legs are not on the body’s lateral means that they were endotherm animals.

text-align: justify;">Finally, the lecturer argues that although dinosaurs had haversian canals like endotherm animals, they also had growth treams. these structures could stop or slow growth, which can be called periodic growth, and this ability is not peculiar from endotherm animals. The text, on the other hand, states that the presence of haversian canals is an indicator that dinosaurs were endotherm animals.
