HideShow timer Statistics

An electric-power company gained greater profits and provided electricity to consumers at lower rates per unit of electricity by building larger-capacity more efficient plants and by stimulating greater use of electricity within its area. To continue these financial trends, the company planned to replace an old plant by a plant with triple the capacity of its largest plant.
The company’s plan as described above assumed each of the following EXCEPT:
(A) Demand for electricity within the company’s area of service would increase in the future.
(B) Expenses would not rise beyond the level that could be compensated for by efficiency or volume of operation, or both.
(C) The planned plant would be sufficiently reliable in service to contribute a net financial benefit to the company as a whole.
(D) Safety measures to be instituted for the new plant would be the same as those for the plant it would replace.
(E) The tripling of capacity would not result in insuperable technological obstacles to efficiency.

D looks good to me. All other answer choices must have been assumed by the argument.

Hmm... doing this would be way too time consuming on the real test, but I'm going to apply negation to the assumptions:

A - If demand will NOT increase in the future, then there is no point in spending the money to generate electricity that people won't buy, so A is an important assumption.
B - If the expense of the plant replacement exceeds the efficiencies gained, than greater profits might not be achieved; this assumption is important too.
C - If the plant is NOT sufficiently reliable to contribute financially, then the replacement might not be worth the cost;
E - One of the major reasons for increased profits is increased efficiency, if tripling capacity canNOT be done efficiently, then again, the costs might exceed the benefits.

(D) seems to be the best answer here. Again, using negation: safety measures will NOT be the same for the new plant as for the old one. This alone does not undermine the plan; maybe the safety measures will be improved? If so, this could further improve efficiency & lower maintenance costs. Even if this argument fell apart, the company's plan will not automatically do so. So I would bet my GMAT score on (D) in a real test.

EDIT: in addition, all other choices refer directly to either financial profit or efficiency - the two reasons to which increased profit is directly attributed in the original info, (D) is the only one that does not refer to any of the two reasons.
