A group of children of various ages was read stories in which people caused harm, some of those people doing so intentionally, and some accidentally. When asked about appropriate punishments for those who had caused harm, the younger children, unlike the older ones, assigned punishments that did not vary according to whether the harm was done intentionally or accidentally. Younger children, then, do not regard people’s intentions as relevant to punishment. Which of the following, if true, would most seriously weaken the conclusion above? (A) In interpreting these stories, the listeners had to draw on a relatively mature sense of human psychology in order to tell whether harm was produced intentionally or accidentally.
(B) In these stories, the severity of the harm produced was clearly stated. (C) Younger children are as likely to produce harm unintentionally as are older children. (D) The older children assigned punishment in a way that closely resembled the way adults had assigned punishment in a similar experiment. (E) The younger children assigned punishments that varied according to the severity of the harm done by the agents in the stories. 答案是A，题目能看懂，A选项有点模糊，也推不出来。请教NN,怎么通过A削弱的？谢谢！ |
