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.




笨笨的楼主用排除法最后剩下BC两项无法排除

OG的解释说B项是加强 if this were assumed NOT to be true.
楼主死活不动为什么是加强

在楼主笨笨的思维力BC两项几乎是一样的！！！
求高人指点！

排除剩下两个后就取非
B. 取非是The collection fee will significantly affect the

purchasing power of most residents, even if their households

do not reduce the amount of trash they put out.
只是说了消费能力会下降，垃圾量还是一样的，没有起到削弱作用。
C. 取非是The collection fee will induce residents to dump

their trash in the parklands illegally
也就是说人们可能会把垃圾丢到停车场，这样就削弱了提议的做法可

以为停车场腾出更多空间的说法。
其实B和C明显是不一样的，CR题应把握关键信息，这里讨论的是收不

收垃圾回收费对停车空间的影响，消费能力问题是out of scope的。
