C
To reduce waste of raw materials, the government of Sperland is considering requiring household appliances to be broken down for salvage when discarded. To cover the cost of salvage, the government is planning to charge a fee, which would be imposed when the appliance is first sold. Imposing the fee at the time of salvage would reduce waste more effectively, however, because consumers tend to keep old appliances longer if they are faced with a fee for discarding them. Which of the following, if true, most seriously weakens the argument?
A: Many nonfunctioning appliances that are currently discarded could be repaired at relatively little expense.
B: The fee provides manufacturers with no incentive to produce appliances that are more durable.
C: Increasing the cost of disposing of an appliance properly increases the incentive to dispose of it improperly.
D: For people who have bought new appliances recently, the salvage fee would not need to be paid for a number of years.
