In the given set of materials, the reading passage and the lecture deal with bison to debate whether their numbers plummeted with the European colonization. The reading passage is providing three pieces of evidence to prove its point, whereas the lecturer argues against it by providing three compelling rebuttals.
µÎ ¹ø° ¹®´Ü
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, the only thinned the herds. The large scale of early European fur business had a large impact on bison numbers. The professor casts doubt because __________(¸®½º´× Àüü)___________________
¼¼ ¹ø° ¹®´Ü
The reading claims that the second way in which the Europeans decimated the wild buffalo herds was through the use of modern weapons. The bison were unable to escape these accurate, longer-ranged weapons, which, therefore, dramatically lowered the number of wild bison on the American plains. The professor refutes the idea because ________(¸®½º´× Àüü)____________
³× ¹ø° ¹®´Ü
The reading 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 _____(¸®½º´× Àüü)______
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 lecturer argues against it by providing three compelling rebuttals.
µÎ ¹ø° ¹®´Ü
The reading passage asserts the idea that Edmontosaurus simply were not in Alaska and Northwestern Canada. They were plant-eaters, so they likely migrated with the changing of the seasons in order to find grass. The professor casts doubt because __________(¸®½º´× Àüü)___________________
¼¼ ¹ø° ¹®´Ü
The reading claims that due to the fact that numerous skeletal remains were found in a concentrated area, it is thought that they lived in herd-like groups, similar to modern migrating animals. Animals that live in these types of groups are generally migratory. The professor refutes the idea because ________(¸®½º´× Àüü)____________
³× ¹ø° ¹®´Ü
The reading points out that Edmontosaurus¡¯ ability to stand on their hind legs and run would have allowed them to migrate more easily. Moving in this way allowed them to cover larger distances in less time. The professor challenges the idea because _____(¸®½º´× Àüü)______
