标题: OG 12—48，按垃圾重量收费来治理，OG解释没看懂~请教！！
48. 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 households 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.

Reasoning
What assumption underlies the conclusion? The assumption will be a statement that has to be true in order for the argument’s premises to provide a solid reason for believing its conclusion. To reach the conclusion that the plan will protect the parkland, the argument must assume that county residents will comply with the new fee, reducing both the trash they generate and the need to convert parkland to landfi lls. It is assumed that residents will not resort to some illegal means of avoiding the new fee, and it is certainly assumed that they will not contribute to the destruction of parklands by dumping trash in them illegally.

这道题的这个解释，没有看懂，应该如何理解？
请教各位了！

解释了老半天，其实假设就是一句话：居民们都是遵纪守法的，不会因为要交垃圾处理费而自行偷偷倾倒垃圾到公共场所。

话说听听啊我怎么OG12 的48 怎么是这个题和我书上不一样啊

这个题可以理解为~
交费=>减少trash=>保护了parkland
削弱方向：是否交费会起到反效果？

这道题答案C可以理解
但是对错误答案的OG解释心存疑虑？？？

A- Even though the fee may indirectly have this effect, the argument need not assume that it will; perhaps residents will continue to buy as much, but will make longer use of the product, or recycle it.

B-The argument would be stronger if this were assumed NOT to be true.

还有D为什么不能选啊？？？

谢谢NN帮忙解释一下
