The professor casts his doubt on the three competing theories and gives explanations for himself.
The first one that the Chaco structures were residential, each of which can hold hundreds of people in it. Although the Chaco house appear similar to the apartment buildings at Taos, there must exists the compatible facilities such as fire places to cook food in. The number of that kind of places only satitsfying around 10 families, however, it is far from enough for almost 100 families. So it is not reasonable for human residence.
The second theory that the Chaco houses are used for food storage is also not supported by the provided evidences. In spite of large enough room to reserve maize, the houses do not cover any food trace or container for storage in long period of time with spoiling should require containers instead of being putting on floor.
As to the ceremonial centers part, the professor mentions that other kinds of material to build the structures are ought to stay with the pots such as construction trash like sand, stone ect. Construction workers would throw them away together, not in separate way instead.
Therefore, the evidences supplied above well illustrate the doubt they cast on the three theories.

The first one(possible theory passage mentioned is) that the Chaco structures were residential, (since)each of which can hold hundreds of people in it. Although the Chaco house(houses) appear similarto the apartment buildings at Taos, (the professor argues)there must exists the compatible(living)facilities such as fire places to cook food in.

Therefore, the evidences supplied above well illustrate the doubt they cast on the three theories.
other kinds of material marerials
ect 这样的缩写词不要出现在文章中
throw them away together 这个没看明白
the evidences supplied above well illustrate the doubt the doubts
正如上楼同学所说注意用词。另外最后一个分论点我没有看明白。貌似是阅读中说那些罐子是为ceremonial准备食物的,而教授说罐子里有建筑材料,所有否定了阅读中的第三理论。ETS说要从考生的作文中了解阅读和听力的主要信息,哪怕读者事先不知道阅读和听力的内容。光从楼主的论述中没办法看明白。
