But no negotiations will be held until international troops enforcing the cease-fire have demonstrated their ability to counter any aggression from either side, thus suppressing a major incentive for the two sides to resume fighting.
If the statements above are true, and if negotiations between the two sides do begin soon, at the time those negotiations begin each of the following must also be true EXCEPT:
(A) The cease-fire has not been violated by either of the two sides
(B) International troops enforcing the cease-fire have demonstrated that they can counter aggression from either of the two sides
(C) A major incentive for the two sides to resume hostilities has been suppressed
(D) Other countries have exerted pressure on the two sides to the dispute
(E) The negotiations’ reaching an agreement depends in part on the actions of other countries
Must Be TrueX-SN. The correct answer choice is (A)
This stimulus consists of rules that can be diagramed as conditional statements.
UNLESS negotiations begin soon, the cease fire will be violated:
Violated→ Negotiations begin soon,
Negotiations begin soon → Cease fire Will be violated.
Negotiations will be held ONLY IF other countries apply pressure:
Negotiations → Pressure
Pressure→ Negotiations.
An agreement will emerge ONLY IF pressure continues:
Agreement → Pressure continues
continued pressure → agreement.
No negotiation held UNTIL troops demonstrate ability to enforce cease-fire:
Negotiations→ Troops demonstrate
demonstration → negotiations.
We can make many inferences; however, the question stem instructs us to pay attention to the case in which negotiations have begun. In that case, we know that there has been pressure, and that troops have demonstrated some ability to counter aggression.
Answer choice (A): This is the correct answer choice. Since this is a Mistaken Reversal of the first statement, this choice might not be true, which is a good answer to a Must Be True EXCEPT question.
Answer choice (B): This is definitely inferred, so this choice is wrong.
Answer choice (C): This is inferred, because the stimulus states that when the troops demonstrate ability to counter aggression, they suppress a major incentive for the two sides to resume hostilities, and we have already inferred that the troops have demonstrated that ability. This choice is incorrect.
Answer choice (D): This is definitely inferred, so this choice is wrong.
Answer choice (E): This is inferred, because it is a restatement of one of the conditions in the stimulus. Since the stimulus tells us that for negotiations to be successful, international pressure must continue, we know that international action IS NECESSSARY for resolution, or that resolution DEPENDS on international action. This choice is wrong.
