The underground metro rail stations of the city Kolta are known to be dirty. The commuters often do not throw away the trash in designated dustbins, but simply toss them on the station platforms. The new mayor of Kolta has planned to take up an intensive cleaning campaign lasting for four consecutive weeks for all the underground metro rail stations of Kolta. However the outgoing mayor of the city does not believe that the four week intensive campaign would be effective in keeping the underground metro stations clean in the long run after the campaign ends.
Which of the following statements most seriously bring into question the belief of the outgoing mayor?
A. The above-ground platforms of the metro rail stations are also dirty and there is no cleaning campaign planned for them.
B. Regular cleaning schedule for the underground stations will be introduced by the new mayor after the four week campaign ends.
C. The majority of people of Kolta who commute by metro rail stations did not vote for the new mayor.
D. The commuters throw trash in undesignated areas only if there is already trash lying around in these undesignated areas.
E. The amount of trash accumulated on the metro station platforms is enormous, making the cleaning campaign costly.
