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 但是我完全看不懂啊 不理解这题的意思作者: sdcar2010 时间: 2011-4-4 12:19 http://forum.chasedream.com/GMAT_CR/thread-432803-1-1.html作者: powers 时间: 2011-4-4 17:16
我来试试
题眼其实应该是regularly! Gap是频率作者: ssxxtt27 时间: 2011-4-14 20:23
是这么回事 段落里由被ticketed的车的数据推导出所有车的情况 被ticketed的车只是车的一部分,而结论句里所说的车指的是全部车。 in sum 此题的问题在于:又部分推整体!作者: joyous314 时间: 2011-4-17 16:45
哎呀不好意思,这题我刚刚又做了一遍
发现我的解释不对! lz不要被我的胡言论语耽误了.

厄...有点被搞糊涂了...能不能进一步说明一下呢,关于regularly,谢谢!作者: frankiesun 时间: 2011-4-17 21:27
我也在纠结这道题目!作者: sdcar2010 时间: 2011-4-17 21:37
If you negate B, the argument falls apart. Thus, B is the necessary assumption.
