20.   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.（B）

(E) The citizens of Hong Kong will have no restrictions placed on them by the government of mainland China

感觉这道题不应该选B啊~~HK retain its capitalist ways的前提a capitalist Hong Kong is useful to China，那如果HK回归以后，并不能useful to China，进一步说就是is not prosperous，那么HK就不能retain its capitalist ways,并不能说只要HK在回归前retain capitalist.那么回归后就可以一直retain capitalist

我觉得正确答案应该选D啊，是否prosperous才是决定的根本。。。。请NN指点

这题我也错了。。。。
题翻译过来是这样一个过程：
retain资本主义----->繁荣----->资本主义香港对中国有用--->>>能retain

但是我还是不明白。。。。。B为啥对。。。。。请大家再看看好吗

我开始也在B和D直接犹豫不定。后来研究了一下，请指正。
这道题貌似循环推了一圈：capitalist (in 1997)->useful to china->prosperous->capitalist (after 1997), 但实际上并不是互为条件和结论（称为循环论证错误），所以D是错的。

拙见：D的口气是很坚定的，Hongkong 97后会繁荣，但是现在HK 97后是否会还延续资本主义社会都不一定呢，所以答案至少应该是个if。。。then这样的
