If the county continues to collect residential trash at
current levels, landfills will soon be overflowing and
parkland will need to be used in order to create more
space. Charging each household a fee for each pound
of trash it puts out for collection will induce residents
to reduce the amount of trash they create; this charge
will therefore protect the remaining county parkland.

Which of the following is an assumption made in drawing the conclusion above?
(A) Residents will reduce the amount of trash they put out for collection by reducing the number of products they buy.
(B) The collection fee will not significantly affect the purchasing power of most residents, even if their house holds do not reduce the amount of trash they put out.
(C) The collection fee will not induce residents to  dump their trash in the parklands illegally.
(D) The beauty of county parkland is an important issue for most of the county’s residents.
(E) Landfills outside the county’s borders could be used as dumping sites for the county’s trash.

这题主要不太理解原文的“Charging each household a fee for each pound of trash it puts out for collection will induce residents to reduce the amount of trash they create”和c选项“The collection fee will not induce residents to dump their trash in the parklands illegally.”的意思。谢谢各位，帮忙翻译一下，好吗？另外，这题是用“去非”的方法做吗？
