In refuting the alarmists, the author advances his argument by first challenging ______.
A．the source and amount of their data

C．the system of measurement
D．their definition of violence
参考答案
正确答案：D
解析：从文章第四段"When labeling games as violent or non-violent, should a hero eating a ghost really be counted as a violent event?"可以看出，作者首先用修辞问题来探讨什么是“暴力”，为后面的论点作铺垫。因此D their definition of violence是正确答案。
