T9-Q2 请教！

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 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 plants 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

答案是E，我选C。

请解释下E的逻辑关系，谢谢！

if 取消cashew关税－农民从出口中获利

if 取消cashew关税－本地加工厂（均在城市）无原料－造成城市失业上升

结论－取消cashew关税，造成城市失业上升

问反对（可反对条件，或结果）。

E）保留cashew关税－农民失利－从农村来到城市－城市失业上升，得出－保留cashew关税，造成城市失业上升。异因同果。反对条件成立，正确选项。

C）More people in kernland are engaged in farming cashews than in processing them 有迷惑性，但不要忘了我们的目的是什么，是反对原文的结论。城市失业的上升与C的比较无关。

thanks! 也看到了其他帖子的讨论。

但E选项是有一个假设的，就是lack of profit是由于tariff产生的。这属于common sense?

GMAT中一般都有线索，很少去依靠common sense.

看这里

原文If the tariff were lifted and unprocessed were sold at world market prices, more farmers could profit by growing cashews. 与E选项 A lack of profitable crops 对应
