In 1938 an archaeologist in Iraq acquired a set of clay jars that had been excavated two years earlier by villagers constructing a railroad line. The vessel was about 2,200 years old. Each clay jay contained a copper cylinder surrounding an iron rod. The

The reading material states that a set of clay jars found in Iran by local people earlier is not likely being used as electric batteries in ancient time. Reasons are as follows.

First, no metal wires found near the jars means the vessels were not used as battery otherwise they would be attached to some electric conductors. The listening material argues that these vessels were found by local people who were lack of professional knowledge. They may found some metal wires but they were not able to understand the use of them, so the wires were reported.

Secondly, reading material illustrates that the vessels were used to hold scrolls because the copper cylinders inside were exactly like what they found in an ancient city located nearby, where copper cylinders were used to holding scrolls of sacred texts. In the listening text, the professor discusses that the similarity of the copper cylinders does not prove anything. She argued that maybe the people in that ancient city invented these cylinders first, then people found they can be used in other ways, like batteries.

Last but not least, the reading material demonstrates that it is impossible for ancient people to use batteries because there was nothing replied on electricity. The professor in the listening material claims that electricity batteries could be used to shock people as the symbol of some invisible power. Moreover, they can also be used for healing for it can release muscles.
