We have to find something that strengthens that restoring the Somerton train service would not result in any deficits.

A)Once rail service along a given route has been discontinued, there are substantial start-up costs associated with restoring service along that route.
--> Irrelevant. No relation to the conclusion.

B)Most potential Somerton riders are unwilling to pay more for the train service than riders paid last year.
--> The argument never states that the train charges would be more than it was last year. Irrelevant.

C)Very few of the Somerton line's former daily commuters find the means of transportation that they now use as satisfactory as the train service had been
--> If only a few commuters ate satisfied with the current commuting means, it implies they may be willing to use the train again to commute. Hence, strengthens the argument.

D)After the train service was discontinued last year, several stores and factories in Somerton went out of business and their properties have remained vacant
--. No reason why restoring the trains would not have a negative impact.

E)Several retail businesses that once each had a single store, located in the Somerton business district near the train station, now also have branches that are conveniently located in communities near Somerton
--.> Weaken the conclusion by stating that people might not need to commute to get to their job locations/shopping stores.

Answer: C
