In Wareland last year, 16 percent of licensed drivers under 21 and 11 percent of drivers ages 21-24 were in serious accidents. By contrast, only 3 percent of licensed drivers 65 and older were involved in serious accidents. These figures clearly show that the greater experience and developed habits of caution possessed by drivers in the 65-and-older group make them far safer behind the wheel than the younger drivers are. Which of the following is an assumption on which the argument depends? (A) Drivers 65 and older do not, on average, drive very many fewer miles per year than drivers 24 and younger. (B) Drivers 65 and older do not constitute a significantly larger percentage of licensed drivers in Wareland than drivers ages 18-24 do. (C) Drivers 65 and older are less likely than are drivers 24 and younger to drive during weather conditions that greatly increase the risk of accidents. (D) The difference between the accident rate of drivers under 21 and of those ages 21-24 is attributable to the greater driving experience of those in the older group. (E) There is no age bracket for which the accident rate is lower than it is for licensed drivers 65 and older.
答案是A。
题目类型:assumption ; 结论: the greater experience and developed habits of caution导致65岁以上老人要比年轻司机开车安全 ; 选项A 通过排除他因支持结论。
我的问题是: 选项C为什么错? 65岁以上老人恶劣天气相较于年轻司机较小可能去开车 是否和“the greater experience and developed habits of caution”有关呢? 我是觉得支持了结论
希望有小伙伴可以指点一下~ 这种选项类型怎么排除~ 感谢!
