单项选择题

The town of Greenfield recently instituted a substantial supplementary tax on all households, whereby each household is taxed in proportion to the volume of the trash that it puts out for trash collectors to pick up, as measured by the number of standard-sized garbage bags put out. In order to reduce the volume of the trash on which their tax bill is based, Greenfield households can deliver their recyclable trash to a conveniently located local commercial recycling center, where such trash is accepted free of charge.
The supplementary tax provides some financial incentive to Greenfield households to do each of the following EXCEPT

A．sort out recyclable trash thoroughly from their other trash.

B．dump nonrecyclable trash illegally at parks and roadsides.

C．compress and nest items of nonrecyclable trash before putting them out for pickup.
