The Plain of Jars is an archaeological site in the Southeast Asian country of Laos. At the site, hundreds of large stone jars, ranging in size from one to three meters, are scattered across the countryside These numerous large containers are around 2,000 years old. The original purpose of the jars is unknown, but archaeologists have several theories.
The article introduces an archaeological site where hundreds of large stone jars were discovered. The author indicates that the end for these jars is unknown, but several theories explain their existence. Nevertheless, the professor disagrees; he implies that despite these theories, the purpose of these jars is still a mystery. In addition, he states that there are uncertainties about their original purpose.
First, the writer mentions that according to some local residents, the jars may have been used for fermentation. However, the lecturer rebuts this argument and points out that the process of making a stone jar is very time-consuming. Moreover, jars made of clay can serve the same purpose with less amount of effort. In addition, he states that clay jars are just as practical as stone jars for fermentation. As a result, they could not have been used for this matter.
Second, the author remarks that it is plausible for jars to be used as water storage for travelers. In contrast, the professor argues that the routes that travelers used were close to rivers. Therefore there was no need for other sources of water for them.
Finally, the passage suggests that these jars could have been used as a burial site. The speaker believes that, although these large jars may have been used as tombs, there is no indication of covers for them to protect the burial site from the weather. Thus, he notes that this hypothesis is unlikely.
