Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government's effort to reduce urban unemployment over the next five years.
Which of the following, if true, most seriously weakens the argument?
Some of the by-products of processing cashews are used for manufacturing paints and plastics.
Other countries in which cashews are processed subsidize their processing plants.
More people in Kernland are engaged in farming cashews than in processing them.
Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.
情景：Kernland的政府限制了未处理的腰果出口。如果说这个限制可以被打破的话，那么农民将会有更多的是收入。但是，若打破限制可能会让城市的就业问题更加严重。
推理：本题同75题基本相同，此处不做赘述。
选题方式：方案推理有三个评估方向，简而言之，即，答案选项一定和方案的内容相关。
选项分析：
A选项：有些处理腰果产生的副产物可以用来制造颜料和塑料。本选项描述的是生产腰果过程中的副产品还能用来干什么，无关乎于本题的方案，可以排除。
B选项：其它处理腰果的国家会补贴他们的处理厂。本选项和方案无关。
C选项：在Kernland，种腰果的人数要多于处理腰果的人数。种腰果的人数多少和方案无关。
D选项：花费低于世界平均价格来购买未处理的腰果让Kernland的人能用一个有竞争力的价格来卖处理过的腰果。本选项描述的腰果买卖的性质，与推理文段中的方案无关。
E选项：Correct. 没有足够的利润会让很多原本种腰果的农民放弃种植而到城里找工作。当农民出口未处理的腰果得到的利润高了，就不会再有农民向城市跑了，甚至还有城市人来种腰果，所以这个性质可能会导致城市里的竞争压力变小，失业率从而变低。
举例，国际市场价格5元，关税1.2，相当于农民实际卖3.8
而国内价格4元＞3.8，所以农民会卖给国内
如果移除关税，农民卖5元＞4，所以农民会更profit
B别的国家对加工厂有补贴，解释了为什么别的国家出得起5块钱，和其他国家无关
C无关比较 文章关注的是一个数据的自身变化：即加工工厂失业人数的变化，导致的城市失业率的变化。和农民有多少人无关
D加强，加工厂以低于国际市场价格买入：即有关税时，以国内价4元买入，有好处：卖价有竞争力
即有关税时有好处，那么移除关税可能带来坏处：倒闭 失业率增加，所以加强了p-c
E不profit 即有关税时，大量农民进城，有坏处：失业率增加
那么移除关税有好处：失业率减少，削弱
