First of all, the author claims that the carved stone balls were probably used as weapons for hunting and fighting due to their inside have some holes and the balls easy for people to swing and throw it. On the contrary, the professor disagrees. She thinks that if the function of the balls had been used as weapons, the surface of the balls would have contained some damaged instead of smooth.
In addition, the author states that the balls were all in the same size, 70 mm in diameter, it is possible that it provided the function of the standard of the weight. However, the professor refutes the author's idea by indicating that although the size of the balls is all the same, the weights of the balls are totally different. Because the stone balls were made of the different types of rocks such as sand rocks, calcite or other rocks, and every rock has different density.
Finally, the author raises the point that according to the carved stone balls designed, it is possible that it shows that the social status of their society. On the other hand, the professor asserts that the designs on the balls are too simple to represent the social status. Furthermore, if the balls had shown the symbol of the social status, it would have been discovered at the tomb or grave.
