A private bus company gained greater profits and provided bus service

+1 D

It doesn't matter whether it is more difficult to drive the new ones. We cannot assume that a driver for a new bus is more expensive.

Negating D
lets say driving them will be MORE difficult. How much difficult a bit more or They can't drive at all.

If a bit more difficult Cool The buses still work, Generate good ridership, in turn good revenue and profits.
If they can't drive at all. Why to buy it.

So ambiguous option won't gurantee to destroy conclusion on negating.

Answer must be D.

A. Incorrect, new service will be beneficial if it is being fully utilized and that is expected as per plan.
B. Incorrect, Additional cost should come to a breakeven point so that company continue to make profit and forecasted revenue
C. Incorrect, New bus should stand at par with the plan and requirement.
D. Correct, Passage don't talk about driving challenges anywhere
E. Incorrect, Obviously if company is launching something then it assumes that current infrastructure will support this plan.

(D) driving the new buses will be no more difficult than driving the buses they are to replace
in Reversal it says driving new buses will be difficult , The is company planning to stimulate greater ridership, which is still sustained hence the statement is not the assumption.

The plan is to continue the "Financial trends"
Everything will affect the finance of the company, except D.

E: If there are restrictions, then company will not be able to utilize the new buses - hence loss in the business

D: Even if they need new Drivers, it is not affecting their financial strength.

The answer should be E.

If the buses are difficult to drive, at best, the frequency of service will become slower (question doesn't tell about the range of difficulty - 'a lot' or 'a bit'). Still, the company will be able to execute it's plan.

If the DD-buses can't play on the route then the company's plan is not executable.

Background info: A private bus company increased its profits and lowered its fares.
Premise: It was able to do so by running buses more frequently and stimulating greater ridership.
Plan: The company plans to replace its older buses with new, larger buses, including some double-deckers.
Goal of the plan: They hope to continue the trend of greater profits and lower fares.

We’re identifying assumptions the plan relies on.

A. This is a necessary assumption. If they’re going to increase the supply of bus service with the hope of increasing revenue, then there must be increased demand to meet that supply.
B. Also a necessary assumption. Their plan for continued increased profits requires that the efficiency and revenues of the new buses will outweigh any new expenses.
C. Another necessary assumption. The buses must be sufficiently reliable to earn the company a net financial gain, as part of increased profits.
D. This one isn’t necessary. We’re not concerned with driving difficulty.
E. This is a necessary assumption. If it wasn’t met, and the new double-decker buses did face obstacles, then that would impede their ability to operate efficiently in the company’s service area.
Best answer is D.

A - well if the demand doesnt increase, customers wont use bus services and if the bus doesnt assume that, why would they even try to increase quality of the bus.
B - they want to keep continue the profit trend, if the revenue doesnt compensate for the cost, there would be no profit and hence, it must be assumed.
C - again, they want profit, if the newer buses didnt guarantee them financial gain, why tf would they get them? hence, must be assumed. now comes the hard part
E - if it is assumed that the new buses physical attributes will cause any obstacles, they arent likely to get them..because it is going to cause problems that might demotivate customers. so assumed.

the reason i chose D was because it seemed so out of context. everything else relates to profits. because the entire goal is PROFIT. but D, it doesnt relate to profit. driving difficulty can cause hindrances but again, those are curable. train the drivers, get better drivers. they do not hinder the possibility to get profit....so hence.

Answer: A. The plan does not require demand to necessarily grow - revenues are provided by more frequent flights and larger buses, rather than additional passenger traffic.
