大全-7-20.
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.
(E) The citizens of Hong Kong will have no restrictions placed on them by the government of mainland China.
答案給B
可是為何D一定不行呢?
我從文章中推得
資本化-->繁榮 繁榮-->對大陸有用 對大陸有用-->97後可繼續資本化

可推得[資本化-->97後可繼續資本化]也就是答案B
可是為何不能繼續推[97後可繼續資本化,又,資本化-->繁榮,所以,97後因為資本化而繁榮-->97之後繁榮]也就是答案D呢?

D直接提出結論，
可是從這裡我們不確定到底是什麼因素讓香港在97之後將會繁榮。

而且題目的重點是在說明香港是不是會繼續資本化，而不是他的繁榮程度。

注意這一題
其實你把他寫成邏輯圖
你會發現
他會是一個循環邏輯
所以就是說, 要有一個假設, 才會有下一個推論
如果沒有一個假設引頭, 任何一個推論都不會單獨成立
所以一定要先有假設
這就是b跟d的不同點

這是我想很久才想出來的
以前上課聽黃老師講很久
真的聽不懂

問結論, (D) prosporous 是在推論的中間, 不是結論.
(if) {capitalist ways -(then)-> prosporous -(then)-> useful -(then)-> "capitalist ways"} =(thus)=> capitalist ways ...
