How does shutting down one not help the entire system
or
shut down the rural -> No improvement to Rural +Urban(= Total System)
Only logical answer is A.
Or lets find something that says that my total revenue will not increase because expense will not decrease
(B) within the last two decades several of the least used rural routes have been closed and their passenger services have been replaced by buses
Replace by buses. So does this tell me that my total will increase or decrease
(C) the rural routes were all originally constructed at least one hundred years ago, whereas some of the interurban routes were constructed recently
for new high-speed express trains
There was something else that happened. Does this say that there was no effect. There may or may not have been an affect
(D) not all of Appenia’s large cities are equally well served by interurban railroad services
So? what do i do with that
(E) the greatest passenger volume, relative to the routes’ capacity, is not on either category of long-distance routes but is on suburban commuter routes
If it is not on any one. So what is the use of shutting down any one of them.
