The article states that there are some viable descriptions about mass-extinction that occurred 200 million years ago. The author mentions three possible explanations. However, the professor explains that none of these is a good explanation. She refutes each of the theories.
First, the reading argues that one theory involves the decline of sea levels which cause of dying coastal and shallow-ocean species. The author adds that this issue affected food chains, leading to mass extinction. Nevertheless, the professor refutes this point by stating that it is true that sea levels declined, but she explains that it occurred gradually and those species could adapt their lives.
Second, the article claims that another theory involves massive climate cooling, which was related to sulfur dioxide that was released by volcanoes. It was the cause of lowering in global temperatures. The professor contends that it happened in a short period of time. She explains that So2 can combine with the water of the air, and as a result, it will fall on the ground.
Third, the reading avers that the third theory suggests an asteroid strike. It provided large amounts of soil and crushed rock which blocked out sunlight for many months. As a result, most plants died and many animals starved to death. The lecture opposes this point by saying that if an asteroid struck to earth, scientists might find the crater. She adds that they found some craters but those are related to 12 million years before that accident.
