标题: OG12 78 [打印本页] 作者: 鹤源 时间: 2011-10-25 16:06 标题: OG12 78 78. A recent report determined thatalthough only 3percent of drivers on Maryland highways equipped their vehicleswith radar detectors, 33 percent of all vehicles ticketed for exceeding thespeed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are morelikely to exceed the speed limit regularly than are drivers who do not. The conclusion drawn above depends on whichof the following assumptions? (A) Drivers who equip their vehicles with radar detectorsare less likely to be ticketed for exceeding the speed limit than are driverswho do not. (B) Drivers who are ticketed for exceedingthe speed limit are more likely to exceed the speed limit regularly than aredrivers who are not ticketed. (C) The number of vehicles that were ticketed for exceeding the speed limitwas greater than the number of vehicles that were equipped with radardetectors. (D) Many of the vehicles that were ticketed for exceeding the speed limitwere ticketed more than once in the time period covered by the report. (E) Drivers on Maryland highways exceeded the speed limit more often thandid drivers on other state highways not covered in the report. 这个题答案是B。这道题前提和结论我捣腾不明白，求帮忙解释一下。感觉选项里面的各个词都很乱呢~~~~作者: cdwayne 时间: 2011-10-28 09:56
Evidence: A recent report determined that although only 3percent of drivers on Maryland highways equipped their vehicleswith radar detectors, 33 percent of all vehicles ticketed for exceeding thespeed limit were equipped with them.
Conclusion: Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not. ================================== 題目說3%的人有裝雷達，33%超速被開單的人有裝雷達，結論有雷達的人傾向超速。 從evidence到conclusion跳太多，難道不能反過來說傾向超速的有雷達嗎？ 所以(B)直觀假設，簡直就是原文結論改寫，你也可以試著取非驗證看看是否會反駁原文。作者: hanyichen 时间: 2012-4-16 17:42
我认为是这样的，由A得C，过程有问题，需要有个B。 因为装R的人更容易被罚，所以装R的人更容易超速。中间应该加上被罚的人更容易超速。这样就合理了。
