Q20:

During the past year, Pro-Tect Insurance Company’s total payouts on car-theft claims were larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so cannot protect itself against continued large payouts that way.  Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.  Many policyholders will respond to the discount by installing antitheft devices, since the amount of the discount will within two years typically more than cover the cost of installation.  Thus, because cars with antitheft devices are rarely stolen, Pro-Tect’s plan is likely to reduce its annual payouts.

In the argument above, the two portions in boldface play which of the following roles?

A.   The first rules out a certain strategy for achieving a goal; the second presents the strategy that was adopted instead and whose effectiveness the argument assesses.

B.   The first is a judgment made in support of a certain conclusion; the second is that conclusion.

C.   The first has been used as a consideration to support adopting a certain strategy for achieving a goal; the second reports a decision to adopt an alternative strategy.

D.   The first provides evidence in favor of adopting a certain strategy for achieving a goal; the second reports a decision to pursue an alternative goal.

E.   The first is a consideration offered against adopting a certain strategy for achieving a goal; the second is the main conclusion that the argument is seeking to establish.

   Answer: A

答案是A，我选的D。不明白为什么A对？

第一个：PT降低政策，是一个strategy，根据这个就能选A。

D说是一个证据，应该这样理解，PT降低政策（附加一个事实作为证据），这才能说是一个证据

第2个：又是一个strategy，准备提供一个优惠。

并且后文里说，这个plan是对的，是好的，因此还有评价。A里有涉及。

我认为CD错，因为原文没有提到两个方案，主要目的就是想办法支持--买防盗设备。 所以“laternative strategy”错误，个人微薄之建

但是我不明白为什么B错误？ “can not reduce 盗车的数量”，应该是支持“买防盗器材”？
