[問題]OG(11th)Q96

Commentator:
The theory of tade retaliation states that countries closed out of any of another country's markets should close some of their own market to the other country in order to pressure the other country to reopen its market. If every country acted according to this theory, no country would trade with any other .

The commentor's argument relies on which of the following assumptions?

(A)No country actually acts according to the theory of trade retaliation
(B)No country should block any of its market to foreign trade.
(C)Trade disputes should be settled by international tribunal
(D)For any two countries, at least one has some market closed to the other
(E)Countries close their markets to foreigners to protect domestic producers.

答案(D)

想請問思路，題目完全看的懂，但是問假設我竟然沒辦法選，我本來還在猶豫是A or B,結果答案是D
請各位大大指教，thx

A和B你有什麼想法？

如果沒有D，也就是說For any two countries, no one has some market closed to the other.
那作者的結論就不存在啦，因為作者要的是國家之間冤冤相報。

[fiona]

這題的結論是If every country acted according to this theory, no country would trade with any other .

取非不成立，讓我腦筋打結拉~~~
IF條件句不成立的情況是怎樣@@

理論: 有國家被關市場就要給他關回去

推論: 如果大家都照這個理論 (結論)沒有任何國家彼此交易

所以如果沒有D
也就是有兩個國家沒有彼此關 那這兩個國家就會繼續交易囉

(A) (B) 出現武斷字眼 No
(B) (C) 出現不確定字眼 should
(E) additional information 無關痛養
(D) 兩國之間總有不開放的市場,如果因此你關你的市場,我再因此關我的市場,最後就沒有生意可做了.
