need help for a Logic reasoning

Can anyone help answer this logical question? And also please state your reasoning. I have trouble understanding the rationale behind the right answer.

In the past, the railroads in Ostronia were run as regional monopolies and operated with little regard for what customers wanted. In recent years, with improvements to the Ostronian national highway network the railroad companies have faced heavy competition from long-distance trucking companies. But because of government subsidies that have permitted Ostronian railroad companies to operate even while incurring substantial losses, the companies continue to disregard customers' needs and desires.

If the statements above are true, which one of the following must also be true on the basis of them?

(A) If the government of Ostronia ceases to subsidize railroad companies. few of those companies will continue to operate.

(B) Few companies in Ostronia that have received subsidies from the government have taken the needs and desires of their customers into account.

(C) Without government subsidies, railroad companies in Ostronia would have to increase the prices they charge their customers.

(D) The transportation system in Ostronia is no more efficient today than it was in the past.

(E) In recent years, some companies in Ostronia that have had little regard for the desires of their customers have nonetheless survived.

For A, B, C, D, there are no way and no clue to judge the validity of these arguement. (all of them are possible but not neccesary)

E,   railroad companies disregard customers' need, but they survive with government subsidy.

So, there are at least some companies that stay in business without paying attention to customers' need.

thanks a lot, banzhu.

I found myself sometimes have a tendency to bring in outside judgement when dealing with LR, which is not a right approach, but it takes more practice to get over it. May be I don't have to think too compliated and leave things as it stated, but sometimes, in depth analysis/inference is necessary to make the right choice, i might not know what is the fine line.

Unlike Reading and Logic Game, my LR score has always fluctuated, sometimes substantially, which is very frustrating, and I only have 3 more weeks before the big day. I guess I have to keep on practicing, analyzing the wrong questions, find a reason and move on.
