For a trade embargo against a particular country to succeed, a high degree of both international accord and ability to prevent goods from entering or leaving that country must be sustained. a total blockade of Patria's ports is necessary to an embargo, but such an action wold be likely to cause international discord over the embargo.

The claims above, if true, most strongly support wich of teh following conclusions?
A The balance of opinion is likely to favor Patria in the event of a blockade.
B As long as international opinion is unanimously against Patria, a trade embargo is likely to succeed.
C A naval blockade of Patria's ports would ensure that no goods enter or leave Patria.
D Any trade embargo against Patria would be likely to fail at some time.
E For a blockade of Patria's ports to be successful, internaitonal opinion must be unanimous.

首先你要知道作者的立场是什么才能得到合适的conclusion，题目大致意思是说 a trade embargo 要成功的话必须依赖两个条件：1 international accord（国际的一致性）  2ability to prevent goods from entering or leaving that country. 但是题目又说，the possible embargo in Patria's ports 是需要 a total blockade of Patria's ports 这个action的，但是恰恰这个action 很可能导致条件1 international accord 不成立， 那么作者的立场就是the possible embargo in Patria's ports is unlikely to happen.

再看选项A B C E 没有任何一个选项表达了作者的立场，唯有D说明了 embargo in Patria's ports would be likely to fail. 所以选D选项。
