93. Commentator: The theory of trade retaliation states that countries closed out of any of another country's markets should close some of their own markets to the other country in order to pressure the other country to reopen its markets. If every country acted according to this theory, no country would trade with any other.
the commentator'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 markets 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
各位xdjm帮帮忙，我实在是很困惑这道题，他都已经说哩如果大家都遵守理论就没有交易可言了，那答案为什么是D呢...

ls的解释看不明白，LZ我再给你捋一遍
题目意思，如果大家都照着theory 你关我的市场，我关你的，那世界上就没有trade了
让你选出assumption 前提！
A、其实大家不都是按着theory来的 （lz再看看，楼主的conclusion就是如果大家都按照theory来，就blabla  A选项取非后，不正是“大家都按theory来”，不就是题目原话么？取非还成立，这还是ASSUMPTION么？）
D、2个国家中总有一个被关闭了部分市场，取非，大家都没被关，那不是天下太平么……

我选了A， 理解为什么A 不对。 commentator都已经说哩如果大家都遵守理论就没有交易可言了.事实上，都是有交易存在的。所以前提应该是No country actually acts according to the theory of trade retaliation（没有一个国家是真的实行交易报复理论）， 不然就没有交易可言了。。。。

刷牙不起沫

请问A选项是什么意思

这个理论是被其他市场关闭的国家应该关闭对其他国家的市场，为了使其他国家能够再开放，这里的前提就是首先这个国家应该存在市场被其他国家关闭了，这样才能有should的行动
