Pro-Tect Insurance Company has recently been paying out more on car-theft claims than it expected. Cars with special antitheft devices or alarm systems are much less likely to be stolen than are other cars. Consequently Pro-Teet, as part of an effort to reduce its annual payouts, will offer a discount to holders of car-theft policies if their cars have antitheft devices or alarm systems.
Which of the following, if true, provides the strongest indication that the plan is likely to achieve its goal?
The decrease in the risk of car theft conferred by having a car alarm is greatest when only a few cars have such alarms.
The number of policyholders who have filed a claim in the past year is higher for Pro-Tect than for other insurance companies.
In one or two years, the discount that Pro-Tect is offering will amount to more than the cost of buying certain highly effective antitheft devices
Currently, Pro-Tect cannot legally raise the premiums it charges for a given amount of insurance against car theft.
The amount Pro-Tect has been paying out on car-theft claims has been greater for some models of car than for others.
该题为加强题，方案推理题。从方案可行性上考虑。只有在折扣大于设备售价的时候，客户才会愿意接受这个方案。
Conclusion: 提供discount给安装了防盗设备的holders，能够减少现在持有car-theft policies的保费花销
Assumption：holders of car-theft policies 愿意为了discount去装防盗设备
这是一个方案评价类问题，方案的goal是让保险公司减少保险理赔，方案的具体做法是给装防盗装置的车主一个折扣——那么问题来了：这个折扣到底能不能刺激车主装装置呢？所以C的意思是保险提供的折扣要多于装防盗装置的成本，那么这样，会有更多的人去装防盗装置然后来购买折扣过的保险。
C：折扣超过成本，所以会有更多人来认购这个保险计划，方案可行
