The article and the lecture are both about the usage of carved stone balls found in Scotland. The author of the reading believes that there are three possibilities for the usage of these stone balls. however, the lecturer challenges the claims made by the writer.
To begin with, the author argues that these stone balls used as hunting or fighting weapons. The ancients used some hunting weapons such as arrow and the use of them are completely clear, however, there wasn't any evidence of the usage of these balls as a weapon, it's true that some of them have holes but the other one is completely in perfect shape and these holes maybe came from a crack.
secondly, the writer suggests that these stone were used as primitive weighing measurement tools, on opposit the lecturer rebuts this by mentioning that maybe they have the same size but they are totally different in their weights, they made from various type of stone for example sandstone and their density are different.
Finally, the author posits that they might use it as a social marker, but the lecture position is that it can't be true. some of the stone marked very simply but the other one marked complex. moreover, these stones didn't find in the grave and there were not found any bone that indicates they used as a social mark.
