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.

答案是B，但是B的意思是因为香港在97前一直都是资本主义，所以在97以后也能保留资本主义。但很明显，原文的意思不是这样。我的理解是retain capitalist->prosperous->useful->retain captalist->...，这三个条件是一个首尾相接的死循环，所以结论是香港会一直繁荣（当然同时也一直保留资本主义，一直useful），答案是D，请各位指教。

还是没人回，再up up
