Stimulus

Unless negotiations begin soon, the cease-fire will be violated by one of the two sides to the dispute. Negotiations will be held only if other countries have pressured the two sides to negotiate; an agreement will emerge only if other countries continue such pressure throughout the negotiations. But no negotiations will be side, thus suppressing a major incentive for the two sides to resume fighting.

    Why this is right

    As we evaluated, it would be reading the conditional in opposite-vision to infer anything about the cease fire. That first sentence looks like this: negotiations ? cease fire will be violated. don't begin soon This answer is acting like the first sentence also means this: negotiations ? cease fire won't be violated. do begin soon That's an Illegal Negation. If we fell for this inverted logic, then it suggests that we probably do need to write out these conditionals (at least in the short term), in order to be clear minded on what these rules do / don't say.

    The negotiations’ reaching an agreement depends in part on the actions

    This answer doesn't have anything specifically to do with the fact that we were told that negotiations are beginning soon. It's just derivable from the 3rd rule that "agreements require continued pressure from other countries". So "reaching an agreement depends in part on the actions of other countries".
