Carswith special antitheftdevices or alarm systems aremuch less likely to be stolen than are other cars.Consequently Pro-Teet, as part of an effort to reduceits annual payouts, will offer a discount to holders ofcar-theft policies if their cars have antitheft devices oralarm systems.
Which of the following, if true, provides the strongestindication that the plan is likely to achieve its goal?
(A) The decrease in the risk of car theft conferredby having a car alarm is greatest when only a few cars have such alarms.
(8) The number of policyholders who have filed aclaim in the past year is higher for Pro-Teet thanfor other insurance companies.
(C) In one or two years, the discount that Pro-Teet isoffering will amount to more than the cost ofbuying certain highly effective antitheft devices
(0) Currently, Pro-Teet cannot legally raise thepremiums it charges for a given amount of
insurance against car theft.
(E) The amount Pro-Teet has been paying out on car-theftclaims has been greaterfor some modelsof car than for others.

A 项什么意思，看不懂。解释说的是，If having more cars equipped with car alarms reduce those alarms' effecitvity in preventing theft, then pro-tech's plan is unlikely to achieve its goal.

A选项简单的说就是，只有在少数车装有这个alarm的时候，效果才是最好的（the decrease in the risk of car theft is greatest), 因此如果按照原文的plan执行的话，大家都有alarm了，那么效果反而不好了，因此是削弱，所以不选A
