▶ Your Answer : In the reading passage, there is ample support for the author's claim that how Mima mound were formed. However, the professor in the lecture gives severeal reasons as rebuttal to the author's point. First, the professor contends Mima mound weren't formed by the wind. Mima mound have variety of sediment like grain, rock, sand. Some grain were too large to be carried by the wind. Also, hills created by the wind are irregular, but Mima mound are perfectly round. This casts doubt on the reading passage's claim that Mima mound was built up by sediment was carried by wind. Second, the professor insists there weren't formed melting glaciers. It have cold temperature to create glaciers, but it has wide variety climates. So, glaciers can't exist. This casts doubt on the reading passage's claim that Mima mound were formed by melting glaciers. To conclude, unlike opinion that Mima mound were formed by wind, and melting glaciers, the professor refute the reading passage because some grain in Mima mound were too large to be carried by wind, and there were not exist glacier because variety of climate. |
