In the lecture, the professor discusses why the three reasons presented in the reading passage on the function of carved stone balls are not plausible.
To begin with, the reading claims that the ball could be used as hunting or fighting tools, since a cord can be attached to them. However, the speaker refutes this by saying that, typically, hunting tools from the Neolithic period show signs of wear, which carved stone balls lack.
Secondly, whilst the second hypothesis believes that the uniform shape and size of balls might suggest their function as weighing tools, the lecturer rules out this possibility by asserting that despite the similarities in size, the balls differ in masses, due to the various densities of stone used to make the balls.
Finally, the balls can not be the symbol of social status of their owners. Ancient people tended to be buried with their possessions, as the instructor points out, but the balls were never found in such graves. In addition, many balls are simple in design, rather than having complex patterns. This is in contrary to the statement that balls are likely to present their owners' social status.
In conclusion, based on the analysis given by the speaker, the theories that the balls can be weapons, weighing tools and symbol of social status simply do not stand.
