The main idea of both the reading and the listening is about causes of mass extinction that occured 200 million years ago in Triassic Period. The author of the passage, by providing three theories, claims that the mentioned theories are the reasons that caused the living creatures to extinct. However, the lecturer refutes that and says that these theories may be plausible but not good reasons for the mass extinction for the following reasons.
First of all, the writer of the article brings about the decrease of the sea levels and fluctuations in Triassic Period, which lead to destruction of coastal and shallow ocean species and distrupting the available food chains. The professor, on the contrary, rejects that by saying that coastal and shallow ocean species can adapt gradual changes. These fluctuations happened for years and gradually, so these species could adapt to it. Consequently, there must be sudden change that caused the extinction.
Second of all, the writer of the text posits that massive cooling of the climate that caused by volcanoes release of so2 is responsible for the elimination of species. The speaker, on the other hand, rebuts this and explains that so2 remains in air in short periods and even it is still present in the air. Exessive so2 clears out from air by different processes like combining with air and rains.
Thirdly, the writer points out that asteroids are the reason of the extinction. Conversely, the professor refuse this notion too and says that the massive asteriods do not match with the time of the extinction and closest collision of massive rocks to that period is about 12 million years before extinction. Hence, asteroids can't be the reason of the extinction.

Suggestion: can't; cannot
...ars before extinction. Hence, asteroids cant be the reason of the extinction.
