101. 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 would be likely to cause international discord over the embargo.
The claims above, if true, most strongly support which of the 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, international opinion must be unanimous.

想问一下B为什么错

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
这句话指出了high degree of both international accord 和 ability to prevent ...这两个是缺一不可的条件，而B项的international 的unanimously 违背了第一个条件，所以是不对的。

    在其他贴子上看到的对B解释 所以看的我不明白了 你看看他是不是解释错了

B As long as international opinion is unanimously against Patria, a trade embargo is likely to succeed.（两个条件只满足了前一个）

不应该是“两个条件只满足了前一个吧” 是像你说的“违背了第一个”
