Q15:

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.

题干说出口高关税使得nuts都在国内卖.  但后来说提高关税使更多农民可以在世界市场价格下获利, 如何获利?关税都提高了

谁给解释一下

谢了

我的理解:非加工的腰果能卖个好价钱（即去除出口关税），但政府不想这样，因为加工

厂都在城里，（如果去掉关税，农民们都种并且卖非加工腰果的话，城里加工厂可能就

会关门）所以就会使政府减少城里失业的目标无法实现。

削弱reasoning应该是说：不去掉关税，也不会有城里的失业。选项E是说如果（保持高

的出口关税）种腰果无利可图的话，很多小农就会跑到城里（造成城里新的失业人口，

也就是说政府减少城里失业人口的目标仍然没有实现）

应该是E吧？
