Both the reading passage and the lecture discuss the mass extinction happened 200 million years ago at the end of Triassic period. Albeit the reading passage brings three possible reasons why the extinction happened, the lecturer believes non of them is convincing and refutes them all. Now in the following article, I try to explain why the lecturer doesn't accept the reasons provided by the author.
First of all, the author points to a reduction in sea levels during this period causing problems in food chain. Although the lecturer agrees with the fluctuation in sea level, she states that coastal and shallow water were gradually changing making the modifications in food chain adaptable. Also for the food chains being affected all over the world, we do need a much more sudden event, not a gradual one which animals would be able to adapt to it.
Additionally, the author mentions a massive climate change due to volcanic eruptions producing lots of SO2. Yet, according to the lecturer, in order for SO2 to take action, we need a much longer period of time. As a matter of fact, in short period of time SO2 combines with water in atmosphere and produces acid rain. Therefore, SO2 produced by volcanic eruption, couldn't have stayed in atmosphere to cause climate change.
Finally, the author discusses the possibility of an asteroid strike, blocking sunlight. Thus, lots of plants died out of not receiving sunlight and animals depending on those plants came into extinction too. However, few scientists believe in such hypothesis as they couldn't have found a crater returning to that time. And they just could find a crater returning to 12 million years before the extinction, and this amount of time seems too long to assume that the strike would have anything to do with the extinction. In conclusion, the reasons provided by the reading passage doesn't sound logical.
