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?
错选C。逻辑链的理解是：however因为加工厂都在城市，取消税会严重影响政府降低失业率的努力在未来5年。CE里，我觉得E是支持，driving increasing number of farmers into the cities不就是会hamper effort to reduce unemployment 吗？另外觉得however之前是迷惑信息。

通过unlike A,后面接对应的名词，排除了A.B,但已有解答关于to recognize 修饰谁，有疑问，难道不修饰最近的名词吗？那C是people,D是disinclined,E是disincination,在此就排除了C因为语义不通，然后用while 后面加V，主句变成有两个动词修改了原意，不如while doing,排除E。
