The city council of Lakeville has decided to promote the use of bicycles over cars in order to reduce air pollution in the city. As part of this initiative, the council plans to build more bicycle lanes and offer free bicycle maintenance services to residents. The council believes this plan will lead to a significant decrease in car usage and thus reduce air pollution levels in Lakeville.
Which of the following, if true, most seriously weakens the argument above?
(A) Other cities have successfully implemented similar initiatives to promote bicycle use.
(B) Lakeville has a temperate climate that is ideal for outdoor activities like bicycling.
(C) The bicycle maintenance services will be funded through a slight increase in local taxes.
(D) A significant proportion of Lakeville's air pollution is caused by industrial factories, not car emissions.
Inreased usage of bicycles will reduce air pollution because of cars but can not reduce air pollution because of industrial factories. This statement weakens the conclusion that increased use of bicyles will lead to reduce air pollution.
Correct
(E) Many residents of Lakeville already own bicycles but prefer to use their cars for daily commuting.
