大全13-16

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.（D）

(E) For a blockade of Patria’s ports to be successful, international opinion must be unanimous.

不明白为什么选d

我选了e，e为什么不对呢

E is irrelevant

We have to draw a conclusion from the argument above.At the end of the argument,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.If the internation discord occured,the high degree of accord will be broken.As we know ,high degree of accord is need to sustain a trade embargo.

Hence ,the embargo will fail at some time.So D is the answer.

明白了

为什么说D是irrelevant?D的意思不是说要成功,意见必须一致么?
