某国连续四年的统计表明，在夏令时改变的时间里比其他时间的车祸高4%。这些统计结果说明时间的改变严重影响了某国司机的注意力。 得到这一结论的前提条件是( )。
A．该国的司机和其他国家的司机有相同的驾驶习惯
B．被观察到的事故率的增加几乎都是归因于小事故数量的增加
C．关于交通事故发生率的研究，至少需要五年的观察
D．没有其他的诸如学校假期和节假日导致车祸增加的因素
参考答案：D
解析： 找一个推理的前提条件，就是要找这样的选项，如果没有这一条件，推理就不成立或结论就推不出。在本题中，如果没有D项，也就是车祸事故的增加还有其他因素的影响，那么，就不能确定的说是时间改变的影响。因此，题干的推理必须有D项作为前提。
