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?
D For any two countries, at least one has some market closed to the other.
why why why this is the right answer??Could anybody explain it to me？作者: haoye12321 时间: 2011-9-25 21:40
(D) For any two countries, at least one has some market closed to the other.
If you negate this statement, then any two countries has no market closed to the other, what would happen? Nothing! The trade goes on. Therefore this is a necessary assumption that the argument relies on.作者: sunincity 时间: 2011-9-28 06:13
我的理解是：
Commentator的潜台词是：“这个理论根本就说不通。因为，【假设一个国家
的确关闭了自己的某个市场，即， assumption】，那么，一定这个理论成立，
多米诺排骨效应之下，岂不最后大家都关了自己所有的市场，以致于没有
trading了？”
括号中的部分就是要问的Assumption。
