I am going to go against the grain on this one. I actually don't think the answer is sensible. A should be the correct answer.
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. Correct
(B) As long as international opinion is unanimously against Patria, a trade embargo is
likely to succeed.
B is clearly out. It goes in the opposite direction.
(C) A
naval blockade of Patria's ports would ensure that no goods enter or leave Patria.
C is out ...we need international accord AND closing of the ports.
(D) Any trade embargo against Patria would be likely to fail at some time.
In my view, the problem with this choice is that it presupposes that the embargo is a success. To get that success one would need accord AND limitations on what goes in and out of the country. We also know that a total embargo would cause discord...which clearly violates one of the conditions. Therefore, a trade embargo would not be successful to begin with (because of such discord). So...how can we infer that they are likely to FAIL if they never succeeded to begin with?
(E) For a blockade of Patria's ports to be successful, international
opinion must be unanimous.
Unanimous takes things too far. All the passage says is that a HIGH DEGREE of accord is required.
Can experts chime in on this?
