求助：各位NN，帮忙看下这道题吧，狒狒逻辑里的，看了好久答案也没看懂。。。。。

10. In order to pressure the government of Country S to become less repressive, some legislators in Country R want to ban all exports from R to S. Companies in R that manufacture telecommunication equipment such as telephones and fax machines have argued that exports of their products should be exempted from the ban, on the ground that it is impossible for a country to remain repressive when telecommunication equipment is widely available to the population of that country.


Which one of the following is an assumption on which the argument given by the manufacturers depends?

A. The government of S has recently increased the amount of telecommunication equipment it allows to be imported into the country.
B. The telecommunication equipment that would be imported into S if the exemption were to be granted would not be available solely to top development officials in S.

C. A majority of the members of R’s legislature do not favor exempting telecommunication equipment from the ban on exports to Country S.

D. Of all exports that could be sent to Country S, telecommunication equipment would be the most effective in helping citizens of S oppose that country’s repressive government.

E. Without pressure from Country R, the government of S would be able to continue repressing its citizens indefinitely.


狒狒的答案：
The correct answer is B.

See: Assumption question

Think: I have to find the conclusion, then the evidence, and from them figure out the central assumption.

Do:

       Conclusion: The “what” of an argument

In this case:    

In order to pressure the government of Country S to become less repressive, some legislators in Country R want to ban all exports from R to S.

       Evidence: The “Why” of an argument  

In this case:    

It’s impossible for a country to remain repressive when telecommunication equipment is widely available to the population of that country.

Assumption:  Facts or ideas, not stated in the passage. The assumption must be true if the argument is to be considered valid.  The assumption typical directly links the evidence with the conclusion. The best way to tackle it is to negate it.

In this case:    

The telecommunication equipment that would be imported into S if the exemption were to be granted would not be available solely to top development officials in S.

If we negate the assumption, the conclusion can’t come to pass.

:

The telecommunication equipment that would be allowed to export into S (exempted) would be AVAILABLE SOLELY to top development officials in S, then the proposal to pressure the government of Country S to become less repressive by using ban will be failed. As a result, the argument that manufacture gave that telecommunication equipment such as telephones and fax machines have argued that exports of their products should be exempted from the ban will be failed.

最后这一段看不懂啊~~~总觉得好像说反了，不知道是不是我理解错了。。。。麻烦各位指点一下啊！

谢谢谢谢~~~~~

B说不是仅仅供给top development officials in S，所以应该exempted from the ban。

最后一段他有说If we negate the assumption, the conclusion can’t come to pass.

所以最后一段是对B取非（此段在给你解释为什么B是对的）说如果would be AVAILABLE SOLELY to top development officials in S。对S过施压的建议就会失败。

R国当然不会同意让这些公司的货物exempted from the ban 了。

我是这样理解的，不知道对不对~~呵呵~~

"Companies in R that manufacture telecommunication equipment such as telephones and fax machines have argued that exports of their products should be exempted from the ban, on the ground that it is impossible for a country to remain repressive when telecommunication equipment is widely available to the population of that country. "
注意题目划线部分与答案的对应关系。

因为Companies in R 出口到S国的products不仅仅提供给 top development officials, 所以 telecommunication equipment is widely available to the population of that country.  而这正是 S 国政府不能 remain repressive  的原因。

其实就是说，这些进口的equipment 可以抑制S国 政府 become too repressive.

这是我的理解~ O(∩_∩)O

我看讲义上说的是选项取非后，如果起削弱作用，就是答案。我自己做这类题型就用这个方法，挺管用的。
