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，我选了D！

请问怎么理解？？？

还有，大家平时做boldface题有没什么方法？感觉我一座就错。。。唉~~~~

谢谢。。。

我也错啊！！！

我也觉得boldface一定错。我对逻辑就很头痛。。。

哪个牛牛来说说救救我们嘛。。

文中说保险公司无法削减保险条款的数量，因此采取了对安装车用防盗设施的客户打折的做法。

这种做法是保险公司鼓励客户安装防盗设施，从而用防盗设施的折扣对冲整车被盗的风险及损失，相当于损失部分利润而换取整体利益。

首先我们可以发现这个句子里面没有否定词，如However,but所以先判断这断话没有转折结构，两个句子在表达一个方向的内容。

然后要找到这句话的作者的结论，“Pro-Tect's plan is likely to reduce its annual payouts.”这个结论包含在最后一句话中，所以A,C,E首先就可以排除了，因为这三句都是说最后一句可以支持主观点，而最后一句本身就包含主观点。

然后比较BD。

B说：提出一个问题,文章尝试去解决,后半句对这个解决方法给出判断.

D说一个事情的发展，文章要去解释。后半句做出一个预测去支持解释。

D有两个问题，一是后半句是本身结论，用结论支持解释本身不太好；其次我们根本找不到这个解释是什么,很明显两个黑体字之间是这个公司给出了一个措施和这个措施的作用，这就是提出一个方法，而不是要去解释什么东西。

不知道这么说楼主明吗？

新东方的方法做黑脸题比较有效。花那么多钱上新东方其实帮助不大，不过解决黑脸问题还比较有效。。

我想问下这个B修饰关系是怎么样的？读不懂……

The first presents a problem a response to which the argument assesses

是说第一句对一个problem 提供了一个response么？？？
