我觉得问题出在regularly这个词上,这个题的结论是more likely to exceed the speed limit regularly than are drivers who do not. 但之前所说的with radar or not之类的并没有提到超速这个事是regularly的,如果没有B 这个assumption前面所介绍的一些数据和结论挂不上勾。答案A并不能说明为什么结论提到的regularly这个问题
A选项其实也可以推出来结论 does not make A necessary for the argument to hold. Only if when negating A makes the argument fall apart, A is necessary for the argument.
