In the given set of materials, the reading passage and the lecture deal with the bison to debate whether their number plummeted with the European colonization. The reading passage is providing three pieces of evidence to prove its point, whereas the professor argues against it by providing three compelling rebuttals.
The reading passage asserts the idea that the first reason for the sharp decline in their numbers was overhunting. While the Native Americans took bison in large numbers, they only thinned the herds, taking only what they could use. The large scale of early European fur business had a large impact on bison numbers. The professor casts doubt because
The reading passage claims that the second way in which the Europeans decimated the wild buffalo herds was through the use of modern weapons. This allowed them to take out large numbers of the animals with more accuracy. The professor refutes the idea because
The reading passage points out that the final reason for the dramatic decrease in the number of roaming bison after European settlement was the westward expansion of European, and later American, settlements. Domesticated animals were then in competition with the bison for natural resources and grazing land. The professor challenges the idea because

In the given set of materials, the reading passage and the lecture deal with Edmontosaurus to debate how they survived the extremely cold winters of Alaska and Northwestern Canada. The reading passage is providing three pieces of evidence to prove its point, whereas the professor argues against it by providing three compelling rebuttals.
The reading passage asserts the idea that the most likely explanation of Edmontosaurus’ ability to survive these extremely cold winters is that they simply weren’t there. As mentioned earlier, they were plant-eaters, so they likely migrated with the changing of the seasons in order to find grass. The professor casts doubt because
The reading passage claims that a second factor supporting the yearly migration of the Edmontosaurus is the discovery of their remains in the polar ice region. Animals that live in these types of groups are generally migratory, not only because of weather changes, but also because concentrated numbers of animals tend to strip their environments of resources and they must move elsewhere for food. The professor refutes the idea because
The reading passage points out that their ability to stand on their hind legs and run would have allowed them to migrated more easily. Moving in this way allowed them to cover larger distances in less time. The professor challenges the idea because
