In order to save money, some of Company X's manufacturing plants converted from oil fuel to natural gas last year, when the cost of oil was more than the cost of natural gas. Because of a sudden, unexpected shortage, however, natural gas now costs more than oil, the price of which has fallen steeply over the past year. The cost of conversion back to oil would more than negate any cost savings in fuel. So Company X's fuel costs this year will be significantly higher than they were last year.
Which of the following is an assumption on which the argument above depends?
(A) Company X does not have money set aside for the increased costs of fuel.
(B) The increase in the cost of fuel cannot be offset by reductions in other operating expenses.
(C) The price of natural gas will never again fall below that of oil.
(D) The cost of fuel needed by those of Company X's plants that converted to natural gas is not less than the cost of fuel needed by those plants still using oil.
(E) The price of oil will not experience a sudden and steep increase.
Which of the following is an assumption on which the argument above depends?
(A) Company X does not have money set aside for the increased costs of fuel.
(B) The increase in the cost of fuel cannot be offset by reductions in other operating expenses.
(C) The price of natural gas will never again fall below that of oil.
(D) The cost of fuel needed by those of Company X's plants that converted to natural gas is not less than the cost of fuel needed by those plants still using oil.
(E) The price of oil will not experience a sudden and steep increase.

Which of the following is an assumption on which the argument above depends?
1. Company X does not have money set aside for the increased costs of fuel.
OOS
2. The increase in the cost of fuel cannot be offset by reductions in other operating expenses.
OOS
3. The price of natural gas will never again fall below that of oil.
"Will never" is out of scope. We only need a comparision for this year vs last year.
4. The cost of fuel needed by those of Company X's plants that converted to natural gas is not less than the cost of fuel needed by those plants still using oil.
This is the right assumption. As we know that only some of the oil plants have converted to gas, there are still plants running with oil, so in order for the fuel costs to significantly increase we are assuming that the price hike by gas is not offset by the drop in prices of oil.
5. The price of oil will not experience a sudden and steep increase.
It does not matter if the price of oil increases as this only confirms that the fuel costs, which have already been hiked with conversion to natural gas are going to further increase

OFFICIAL EXPLANATION
The conclusion of the argument is that "Company X's fuel costs this year will be significantly higher than they were last year. Why? Because some of the company's plants switched from oil to natural gas when the price of gas was lower, and now the price of gas has outstripped the price of oil. We are asked to find an assumption that is necessary for the argument to work.
(A) Whether Company X has the money to cover its costs does not affect the amount of those costs.
(B) We do not need to assume that the costs cannot be offset by reducing expenditures in other areas in order for Company X's costs to be higher.
(C) We do not need to assume that gas will never be cheaper than oil in order for Company X's costs to be higher.
(D) CORRECT. The author does not take into account the fact that only "some" of the company's plants converted to natural gas. Some of the plants, then, still use oil, which is now cheaper. So in order to conclude that the company will have to spend more on fuel, the author must assume that the extra cost of the natural gas for the plants that converted is at least as much as the cost of the oil for the plants that did not.
(E) We do not need to assume that the price of oil will not suddenly rise in order for the argument to work.
