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 passage discusses the Plain of Jars and the theories concerning the reason for their existence. The lecturer argues against the reasonings, pointing out that the purpose of these jars remains mysterious to this day.
First, the author says that the jars were used for fermentation. However, the lecturer explains that in ancient times jars made of clay were the widespread way to ferment food and drinks. Even though stone jars could be used for the same purpose, the process of making stone jars was arduous and took a significant amount of time and effort. The stone jars are unlikely to have been used for fermentation while clay jars were available.
The second theory considers the jars to have been used as water storage for travelers since they were situated near an ancient trade route. The lecturer disputes this by pointing out that such routes were typically made alongside water sources and rivers; hence, the travelers did not need the jars to provide fresh water.
Third, the article points out that the jars might have been used as burial sites due to the artifacts found within them. The lecturer points out that the tomb theory may have been reasonable if these jars had been covered to protect the remains of the deceased and artifacts from different weathers and thieves aiming for the expensive artifacts. However, the tomb theory is unlikely to be true because there are no covers.
