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


11 An experiment was done in which human subjects recognize a pattern within a matrix of abstract designs and then select another design that completes that pattern. The results of the experiment were surprising. The lowest expenditure of energy in neurons in the brain was found in those subjects who performed most successfully in the experiments.
Which of the following hypotheses best accounts for the findings of the experiment?
(A) The neurons of the brain react less when a subject is trying to recognize patterns than when the subject is doing other kinds of reasoning.
(B) Those who performed best in the experiment experienced more satisfaction when working with abstract patterns than did those who performed less well.
(C) People who are better at abstract pattern recognition have more energy-efficient neural connections.
(D) The energy expenditure of the subjects brains increases when a design that completes the initially recognized pattern is determined.
(E) The task of completing a given design is more capably performed by athletes, whose energy expenditure is lower when they are at rest than is that of the general population.

I still wait for some more ans on Q 1

but for II ...why cant the ans be A...
neurons in the brain react less = lowest expenditure of energy in neurons

1) I am stuck btw A and D...

while accord is needed, no where does it mention that accord needs to unanimous...so D it

2) C

I would go with D and C

For the first, all the other choices weaken/don't apply to the conclusion.

I agree with D for the first question too. If A and B has to happen for C to happen, and if A would lead to non B, then A and B can never happen in the same time and C would not happen, in other words, the embago would fail.

Question 1

Premise
1) For trade embargo to succeed, both intl' accord and ability to prevent good from entering or leaving that country must be sustained
2) Total blockade of Patria's ports is nescessary to an embargo, although such an action will cause international discord

If there is going to be international discord, then the conclusion that is most likely to happen is given in D. The trade embargo might not succeed.

In A), we can't support if the international community will favor Patria. We are only told the community will not be happy with a blockade.
In B), it changes the requirement of a successful trade embargo
In C), the word 'naval embargo' isn't even mentioned in the passage
In E), the conclusion is twisted. For the trade embargo to succed, international opinion must be unaminous, but for the blockade to succeed, opinion is not important.

D is the best choice.

In 1 one can discard all the answer except D. In 2 one can discard all the questions except C. SO I choose D and C.
