If the county continues to collect residential trash at current levels, landfills will soon be overflowing andparkland will need to be used in order to create morespace. Charging each household a fee for each poundof 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.
OG关于A选项的解释：even though the fee may indirectly have this effect, the argument need not assume that it will.这是什么意思呢？是说即使fee间接产生了这个effect，argument也不可以假设它？？？
同类还有D的解释：the argument need not assume this, and nothing in the argument indicates that it does. |
