A private bus company gained greater profits and provided bus service to the area at lower fares by ruuning buses more frequently and stimulating greater ridership. Hoping to continue these financial trends, the company plans to replace all older buses with new, larger buses, including some double-decker buses.
The plan of the bus company as described above assumes all of the following except:
A.    the demand for bus service in the company’s area service will increase in the future.
B.    Increased efficiency and revenues will compensate for any new expenses the company incurs.
C.    The new buses will be sufficiently reliable to ensure the company a net financial gain once they are in place.
D.    During the new buses will no more difficult than driving buses they are to replace.
E.    The larger, double-decker buses will not face obstacles such as height and weight restrictions in the bus company’s area of service.

Ans: D, I choose C, Actually I think all choices are assumptions. I don’t know how to distinguish those assumptions and the irrevelant.

Joy,

D is the answer because it is not related to the argument, which is "replacing will continue the financial trend".

So all the assumptions should have something to do with the financial result.
A. Assumption. If demand is not growing, it does not make sense to increase capacity. In another word, if no demand, replacement will not make the company better off financially.
B. Same thing. It means that the expenses will be covered. If not, financially the company is worse.
C. Same as previous two. And the wording makes it very clear.
D. Not related to the going concern of this company or its financial situation. If it makes extremely hard and the company has to hire some high-pay drivers, it might be the answer.
E. It concerns the operation of the company. If the new buses are not operable, it would not for sure help the company financially.

D is unrelated. Similar answers can be "the new buses will increase the noise level, which will kill some wild animals". Can you see how it is unrelated to the argument?
E
