I would go with "D".
Basic assumptions :
1. Either of these 2 factions would win.
2. Perry's faction => Certain economic suffering. maybe military suffering.
3. Tucker's faction => Certain military suffering, maybe economic suffering.
A. Since either of the factions are going to gain control of govt, one suffering is assured. False.
B. Perry's faction's control ensures economic suffering, but Tucket's faction could cause economic suffering too (which is not ruled out). False.
C. That the nation would not suffer militarily when Perry's faction wins and that the nation would not suffer economically when Tucker's faction win is not assured. False.
D. True. Military suffering would definitely caused by Tucker's faction and maybe by Perry's. So from knowing that the nation suffered militarily, we cannot definitely say who won.
E. Violates our assumption #1. False.
Please post differing viewpoints. Thanks.
