These statistics show that these time changes adversely affect the alertness of California divers. The conclusion in the argument above is based on which of the following assumptions? (A) Drivers in California as well as those in the rest of the United States have similar driving patterns. (B) The observed increases in accident rates are due almost entirely to an increase in the number of minor accidents. (C) Four years is not a sufficiently long period of time over which to judge the phenomenon described. (D) There are no other factors such as school vacations or holiday celebration that cause accident rates to rise during these weeks. (E) A time change at any other time of years would not produce a similar increase in accident rates. 例题解析：连续四年的数据都显示(现象或陈述事实)，当时间转到 夏令时，有4%更多的机动车事故发生是在加利福尼亚 ，当时间转回到 正常时间时，交通事故率也很高。(两个时间一种现象)。这些数据显示 出来，时间的改变实际上影响了加利福尼亚司机的灵敏度。(结论) 关键词：switch
