During the past year, Pro-Tect Insurance Company's total payout on car-theft claims has been larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so it 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 such 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 and the second are both evidence offered by the argument as support for its main conclusion.

(B) The first presents a problem a response to which the argument assesses; the second is the judgment reached by that assessment.

(C) The first is the position the argument seeks to establish; the second is a judgment the argument uses to support that position.

(D) The first is a development that the argument seeks to explain; the second is a prediction the argument makes in support of the explanation it offers.

(E) The first presents a development whose likely outcome is at issue in the argument; the second is a judgment the argument uses in support of its conclusion about that outcome.

答案是B，理不出头绪，麻烦大家帮忙解释一下。谢谢！

第一句是在揭示问题，以及引出我们这段话到底要干什么~~就是因为公司入不敷出，公司才要想办法，文章才要讨论有什么办法。

第二句就是通过评估一个办法，得出了对这个办法的评价结论。提出了一个安装防窃装置的方法，研究后觉得：安装装置可以帮助公司。

A肯定不对 不说了

C The first is the position the argument seeks to establish，文章讨论了半天，不是为了证明这家公司真的是入不敷出。

D The first is a development that the argument seeks to explain 文章也不是为了解释为什么会入不敷出

E the second is a judgment the argument uses in support of its conclusion about that outcome.  文章的结论就是第二句话。
