大全上P296的一道题

One analyst predicts that Hong Kong can retain its capitalist ways after it becomes part of mainland China in 1997 as long as a capitalist Hong Kong is useful to China; that a capitalist Hong Kong will be useful to China as long as Hong Kong is prosperous; and that Hong Kong will remain prosperous as long as it retains its capitalist ways.

If the predictions above are correct, which of the following further predictions can logically be derived from them?

(A) If Hong Kong fails to stay prosperous, it will no longer remain part of mainland China.
(B) If Hong Kong retains its capitalist ways until 1997, it will be allowed to do so afterward.
(C) If there is a world economic crisis after 1997, it will not adversely affect the economy of Hong Kong.
(D) Hong Kong will be prosperous after 1997.
(E) The citizens of Hong Kong will have no restrictions placed on them by the government of mainland China.

OA：B
也没说1997年之前的事呀。

我怎么感觉题干本身是循环论证的错误

我选的是D

as long as 是“只要”的意思吧，那就是几句“条件→结果”，然后每一句对应带进去看。。。
我是这么理解，除了B另外几个好想都不满足

是一个循环条件题，我用首字母简写。
p->u->c w->p
这个循环从题目给的信息是单循环，不可逆。
找一个根据循环条件推出的结论。
A：p失效，P直接影响u,c w 影响P，所以P不会影响c w。不过这个选项用常识也可以做
B：CW成立，后面循环可走下去。正确
C：c s非条件信息
D：无前提，不能得出这个结论。
E：无关

哇，小穆好聪明。我没理解好 as long as 这个词，所以才看不懂的，一经提点终于明白了。原来这么简单。
谢谢你。

刚开始看没明白字母的意思，现在明白了你的意思。
十分感谢来帮忙。

Hi RRZZR，你看看穆同学写的呀，你比我聪明，估计马上就能明白为什么B对了。
