Train service suffers when a railroad combines commuter and freight service. By dividing its attention between its freight and commuter customers, a railroad serves neither particularly well. Therefore, if a railroad is going to be a successful business, then it must concentrate exclusively on one of these two markets.
For the argument to be logically correct, it must make which one of the following assumptions?
(A) Commuter and freight service have little in common with each other.
(B) The first priority of a railroad is to be a successful business.
(C) Unless a railroad serves its customers well, it will not be a successful business.
(D) If a railroad concentrates on commuter service, it will be a successful business.
(E) Railroad commuters rarely want freight service as well.

IMO A. If Commuter and freight service had been common then the customers will be served well. Can anyone explain why the OA is C?

Because the text does not mention how much the two services have in common, while choice A says that they have little in common...this assumption goes too far, since they could have a lot in common but a few differences that make it difficult to serve both.

C is perfect, since the text states that if they serve both they cannot serve them well, therefore they have to serve only one to be successful. This means that to be successful they must serve them well.

Can E be consider a better choice than others as if we negate E than, railroad commuters will want freight service and thus we cannot focus extensively on one of the markets?
Please correct me if my reasoning is wrong.

I narrowed it to C and E but picked E.

Can someone explain why E is incorrect?

If we negate E..... Railroad commuters mostly want freight service as well.

The conclusion..."Railroads must concentrate exclusively on one of these two markets"......falls apart..

explanations are welcome.

Everyone is talking about Negation. let me try as well -
Negation A : (A) Commuter and freight service have EVERYTHING in common with each other. still need to explain the "success"

Now negate C. Negation (C) Unless a railroad DOES NOT serves its customers well, it will not be a successful business. >> Sounds like free lunch. yeah :-)

Using the Causal Effect. The assumption highlights that the cause( serving one customer well) is the only cause for the effect ( sucessful business)

(A) Commuter and freight service have little in common with each other.so ?
(B) The first priority of a railroad is to be a successful business.priority is not being talked about
(C) Unless a railroad serves its customers well, it will not be a successful business.yes
(D) If a railroad concentrates on commuter service, it will be a successful business.no
(E) Railroad commuters rarely want freight service as well.no . Basically any one of two should be well served
