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?
A, Some of the by-products of processing cashews are used for manufacturing paints and plastics.
B. Other countries in which cashews are processed subsidize their processing plants.
C.More people in Kernland are engaged in farming cashews than in processing them.
D.Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
E.A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities
问题分析：A说处理cashew的一些副产品应用于生产油漆和塑料，没说过，干掉。
B围绕其他国家谈到，范围与原文没关系，干掉。
C说在K这个国家里，种C的比处理C的人要多，没说过，干掉。
D说买这种没有处理过的c能够让processors以比较有竞争力的价格卖了这个nuts，文章说的是关税提升，cashew会卖的不多，这个说的是买cashew会让nut卖的不多，虽然都谈的是卖的价格高低问题，但是这个选项明显张冠李戴，干掉。
Er如果crop不挣钱就会让越来越多的farmer进入城市，文章谈过城市的就业率问题，就业率的前提是这个城市里有人，这个选项与原文存在的前提有关，留着。
