Which of the following can properly be concluded from the data presented in the graph?
选项 A、The 1962 survey was based on a larger sample than the 1992 survey was.
B、In the period between the surveys, denying television privileges was never the disciplinary technique most popular with parents.
C、The four disciplinary techniques featured in the graph were the only disciplinary techniques named by parents in either survey.
D、The 1962 survey allowed parents to name more than one disciplinary technique, but the 1992 survey may not have allowed this.
E、In the period between the surveys, there were no significant changes in the popularity of lecturing children as a disciplinary method.
答案 D
解析 根据本题给出的图表可以清楚地看出，1962年惩罚12岁以下的孩子看电视的各项比例总和显著高于1992年的各项比例总和，因此能合理解释这种差异的选项是本题的正确答案，D选项的内容很好地解释了这种差异，在1962年接受调查的父母因为可以有多种选择，所以最后各项的总和能显著超过100％，而在1992年接受调查的父母因只有一种选择，各项比例之和约为100％，所以(D)为正确答案；(A)选项中指出的“1962年比1992年调查的样本大”不能被用来解释差异原因，因为本题图表中的统计结果是“percent using technique”。另一方面图表中所表明的调查仅仅是1962年和1992年的，所以所有关于：“in the period between the surveys”的答案都无法从图表中得出，于是(B)和(E)不对；从1962年的各项比例分配中，无法看出“the four disciplinary were the onlydisciplinary techniques named by parents”，因此(C)也是不对的。
