来自OG 13的77题 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. 因为用的Helr方法，所以分析觉得这是统计枚举，样本是thirty-three percent of all vehicles ticketed for exceeding the speed limit，结论对象（扩大的范围）是所有人也就是drivers who are ticketed for exceeding the speed limit。 不明白的是照我的理解，用helr分析统计枚举选项中一定提及样本，然而我就选了D。看了OG答案分析觉得蛮对的，自己大概还没完全掌握helr，求高手解答

bjm。

D会削弱观点的，题目是要支持观点的assumption
