标题[问题] 请问有关CR的assumption题
时间Thu Oct 23 22:13:56 2008
从七月多开始准备AT到现在
最近刚做完OG OV OQ以及PP1 PP2
可是一直以来对assumption题一直存在疑惑
每次遇到这种题目总是有点凭感觉的猜 觉得很不踏实
之前补习的时候老师说过"assumption就是选题目中证据跟结论的主题"
觉得还满难意会的@@
不知道有没有牛人愿意分享这类题该怎麽解?
以PP2-CR-40举例好了
40. (32847-!-item-!-188;#058&007552)
A recent report determined that although only three percent of drivers on
Maryland highways equipped their vehicles with radar detectors, thirty-three
percent of all vehicles ticketed for exceeding the speed limit were equipped
with them. Clearly, drivers who equip their vehicles with radar detectors
are more likely to exceed the speed limit regularly than are drivers who
do not.
The conclusion drawn above depends on which of the following assumptions?
(A) Drivers who equip their vehicles with radar detectors are less likely to be
ticketed for exceeding the speed limit than are drivers who do not.
(B) Drivers who are ticketed for exceeding the speed limit are more likely to
exceed the speed limit regularly than are drivers who are not ticketed.
(C) The number of vehicles that were ticketed for exceeding the speed limit
was greater than the number of vehicles that were equipped with radar
detectors.
(D) Many of the vehicles that were ticketed for exceeding the speed limit
were ticketed more than once in the time period covered by the report.
(E) Drivers on Maryland highways exceeded the speed limit more often than
did drivers on other state highways not covered in the report.
答案是(B)
想很久还是不知道为什麽
有牛人愿意解惑吗?
小弟先谢过了^^
