请教费费逻辑第8题

8. The stable functioning of a
society depends upon the relatively long-term stability of the goals of its
citizens. This is clear from the fact that unless the majority of individuals
have a predictable and enduring set of aspirations, it will be impossible for a
legislature to craft laws that will augment the satisfaction of the citizenry,
and it should be obvious that a society is stable only if its laws tend to
increase the happiness of its citizens.

The claim that a society is
stable only if its laws tend to increase the happiness of its citizens plays
which one of the following roles in the argument?

A.      It
is the conclusion of the argument.

B.      It
helps to support the conclusion of the argument.

C.      It
is a claim that must be refuted if the conclusion is to be established.

D.      It
is a consequence of the argument.

E.      It
is used to illustrate the general principle that the argument presupposes.

答案选b， 我选的是e

我知道第一句话是结论，然后最后那句话是用来解释的。

我想我应该是弄混了b选项和e选项的意思，所以请教一下，b和e有什么区别？

谢谢！

小生来试试看

在原文中 it should be obvious 显而易见推断出引导一个结论

B的意思是最后这句话支持了上述讨论的结论

E的意思是最后这句活举例说明了上述讨论假设的基本道理

似乎B的意思贴切，E没有举例的类容存在啊

小生愚见，还请斑竹和大N再帮忙解释一下！

谢谢！

小生有对A和B分不清楚了，还希望有大N来分析一下！
