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.
First； the jars may have been used for fermentation. In fermentation, food or drink is left in a sealed container in order to undergo a chemical change According to some local residents, the jars were originally constructed by a king in order to ferment a special beverage to celebrate a great victory It would be possible to use the jars for fermentation, so the local people's story could be true.
Second, the jars may have been used for water storage. Laos experiences rainy and dry seasons, and finding water during the dry seasons can be difficult. The Plain of Jars is located near ancient trade routes, where traveling traders may have needed drinking water. The jars could have been constructed to collect water during the rainy season so that traders passing through the area would have a source of drinking water during the dry seas on.
Third, it is possible that the Plain of Jars was an ancient burial site, and the jars were tombs (places where human remains are deposited). Much of the contents of the ancient jars is now gone, but they are large enough to hold human remains. Furthermore, artifacts such as metal tools, jewelry, and glass beads have been found in some of the jars. Burying the dead alongside valuable artifacts was a common practice in ancient cultures. Ancient people may have buried their dead in the jars along with the artifacts
The reading states that there are three theories that explain the objective of jars have faound in Laos. The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
The author argues that this jars may were for fermentaing purpose to sealed food and drink in a container. Conversely, the lecturer brings up the idea that in Laos, people used clay for their containers which its production process was easier and more cost effective than stone containers'. As a result, they preferred to use clay containers which was a time and money saving approach.
Furthermore, the reading passage holds the view that because of the location where these jars have been found, they might be for the purpose of providing drinking water for travelers during their trades. On the contrary, the professor underlines the fact that trade routes where located near rivers and streams, as a result they did not need any cotainer to provide fresh water for them, and they had access to them in dry seasons too.
Finally, the reading states that beacuse of the presence of metal tools, beads, and jewelry which have been observed in and near jars, they might be tombs to preserve human remains. In contrast, the speaker dismisses this issue due to the fact that jars which were for keeping and depositing human remains had some covering on them, but not only were these jars not covered, but also there were not any covering near them. In consequence, these theory for jars' objective cannot be accepted.
