Given the statements in the passage, which one of the following statements must be true?
(A) It is possible, but not certain, that the nation will neither suffer economically nor suffer militarily.
(B) If the nation suffers economically, it is certain that Perry's faction has won control of the government.
(C) It is certain that the nation will suffer either economically or militarily, and also certain that it will not suffer both.
(D) If the nation suffers militarily, it is possible, but not certain, that Tucker's faction has won control of the government.
(E) If the nation suffers both economically and militarily, it is certain that neither Perry's faction nor Tucker's has won control of the government.

We know the minimum condition that is nation going to suffer one condition but it can also go to maximum condition that is to suffer both.

IMO: C
Thanks

I think it's D.

The key here, as AIM GMAT suggested, is that we don't have enough information to be certain that one condition implies the other. The passage does not state that Perry's faction will harm the economy WITHOUT affecting military, or that Terry's faction will hurt the military WITHOUT affecting the economy. Each faction could easily impact both military and economy. The only thing we know for certain is that Perry's faction will impact at least the economy, and Terry's faction will impact at least the military, in a negative way. Therefore we cannot conclude with certainty that we will not suffer both economically and militarily, just that we are certain to suffer in at least one way.
