As early as the twelfth century A.D., the settlements of Chaco Canyon in New Mexico in the American Southwest were notable for their "great houses," massive stone buildings that contain hundreds of rooms and often stand three or four stories high. Archaeologists have been trying to determine how the buildings were used. While there is still no universally agreed upon explanation, there are three competing theories.
One theory holds that the Chaco structures were purely residential, with each housing hundreds of people. Supporters of this theory have interpreted Chaco great houses as earlier versions of the architecture seen in more recent Southwest societies. In particular, the Chaco houses appear strikingly similar to the large, well-known "apartment buildings" at Taos, New Mexico, in which many people have been living for centuries.
A second theory contends that the Chaco structures were used to store food supplies. One of the main crops of the Chaco people was grain maize, which could be stored for long periods of time without spoiling and could serve as a long-lasting supply of food. The supplies of maize had to be stored somewhere, and the size of the great houses would make them very suitable for the purpose.
A third theory proposes that houses were used as ceremonial centers. Close to one house, called Pueblo Alto, archaeologists identified an enormous mound formed by a pile of old material. Excavations of the mound revealed deposits containing a surprisingly large number of broken pots. This finding has been interpreted as evidence that people gathered at Pueblo Alto for special ceremonies. At the ceremonies, they ate festive meals and then discarded the pots in which the meals had been prepared or served. Such ceremonies have been documented for other Native American cultures.
The reading passage states that the great houses in Chaco could be built for three purposes. First, they could be used as residential apartmants for hundreds of people as they found hundreds of rooms, second, as food storage for grain maize as they have a suitable storage places, or used as ceremonial centers. However, the speaker has a negative opinion toward the three explanations for why these building were built as such huge.
First, the speaker points out that if these houses were built for living, they should be many fire places for cocking corresponding to such a massive number of people. However, this is not the case.
Second, the lecturer adds those building although the explanation for using them as food storage could be plausible, they didn't, because if that explanation is valid, why are there more Maize in floor?
Third, the reading passage suggests that building could be used as ceremonial centers after excavation as they found large number of old material and broken pots. On the other hand, the speaker has alternative interpetation; He says those materials could be construction trash, which resulted from building, and even those the broken pots probably are regular trash which used by building workers.
