Option A :- INCORRECT
If true, this, this has diverted from the main concern of the argument because it has changed its priorities over the years from putting passengers first to improving its public image and revenues. So, therefore, it doesn't support the argument.

Option B :- INCORRECT
This option, if true might actually enhance swiftRail's prediction but design selection to further efficiency isn't the main concern of the argument.

Option C :- INCORRECT
If most Jetto's citizens are pleased with the system, it means the station is good enough for them but it is also possible that the primary purpose of the station which is to make train travel is more efficient and more convenient hasn't been fulfilled and this will go against the argument. So this option supports the argument but its pillars aren't strong enough to uphold the argument.

Option D :- CORRECT
This option, if true shows that the primary purpose of swiftRail's prediction has been fulfilled because it has been confirmed by the passengers who indicated that efficiency and convenience are the aspect of their ridership experience that are more important to them that are important to them this shows the strong support of this option and to the argument itself.

Option E :- INCORRECT
Well, if true this doesn't in anyway support the argument because the reason for heavily relying on swiftRail for daily commute might be as a result of it been the only available transport option in Jetto.
