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?
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.
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.
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.
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.
Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.
很典型的assumption题。不要看漏了regularly这个词。
开罚单和超速是两回事
MARK
近来的报告确定尽管在Maryland高速只有3%的司机给车装了雷达探测器,所有因超速领罚单的车中33%装了雷达探测器。很明显,给车装探测器的司机更可能经常性超速。
假设题,属增强题范畴
逻辑链:从文中3%和33%的关系---》装探测器的司机更可能领到超速罚单
而文中结论是装探测器的司机更可能经常性超速
所以需要有超速与领超速罚单之间建立关系
A 装rd的司机比不装的司机更少可能因超速领罚单;违背题干事实,排
B 因超速领罚单的司机比没领罚单的司机更可能经常性超速;搭桥增强,符合逻辑链,正确
C 超速领罚单的汽车数比装探测器的车数更多;无关
D 超速领罚单的车中很多领了不止一次罚单;无关
E 超速司机在Maryland比报告外的其他地方更普遍;无关比较。
又是regularly这个词。。。
就是超罚的司机有三成装了雷达,推出装了雷达的司机更可能"经常性"超速。等等!有个gap!超速罚款的司机和经常超速的司机是两码事,所以需要一个assumption|超罚司机更容易经常超速,就b了,取非的话,超罚司机不经常超速,那么何来report里面装雷达的司机更容易经常性超速呢。所以是这是考点!至于a确实是加强的方向,就是雷达司机更倾向于超速,超速频率更高,但是还是不代表他们更加〖经常性〗超速
RD相当于在二者之间架了个桥吧
前提:3%的车装了雷达探测器,因超速被开罚单的车中33%安装了雷达探测器
结论:有雷达探测器的车主比没有雷达探测器的车主更可能经常性超速
加强:因超速被开罚单的司机比没有被开罚单的司机更可能经常性超速
这是我看到的最好的拆解,用英文思维去理解一下更好:https://www.veritasprep.com/blog/2013/03/quarter-wit-quarter-wisdom-an-official-assumption-question/

解析太棒了! 谢谢

前半部分是:有雷达探测器的车比没有雷达探测器的车更容易得到超速罚单
结论是 :有雷达探测器的车比没有雷达探测器的车更容易经常超速
如果形成的假设是得到超速罚单的车更容易经常超速,不就形成结论了嘛,很清晰
结论:装雷达探测器的车主更容易超速。
前提1:高速路上3%的车主装了雷达探测器
前提2:高速路上因超速被开罚单的车主有33%都是装了雷达探测器的车。
没懂为什么assumption“被开过罚单的drivers就会经常性的超速”是能够帮助推出结论的。。。绕进去了 ,求解释!
结论是装了雷达更加“经常性”超速
