Q2:

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?

1. Some of the by-products of processing cashews are used for manufacturing paints and plastics.
2. Other countries in which cashews are processed subsidize their processing plants.
3. More people in Kernland are engaged in farming cashews than in processing them.
4. Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
5. A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

答案选E,我想不通。我选的是D.

我不是NN，这道题也做错了，想了一些原因，交流一下。

关键是题目的命中点-失业率

D虽然说明了提高价格对processer的好处，但是并没有充分的原因说明对解决失业问题有好处；

E提供了一个助长失业率的他因，因为现行的低价导致农村人口向城市涌进，与题目的原来的原因恰恰相反，达到weaken的作用。 

同意。题目是说放开关税后，大家都去卖未加工的产品了，那么在城里面做加工生意的人就没事做了，就失业了。

E 说，导致城里人失业的原因是大量农民工涌进城内。属于他因削弱。
