GWD 31-3-2 这道逻辑题本身逻辑有问题吗？

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.

关于答案（E）有很多讨论，我就不多说了，但是关于题干，我觉得有点问题。

翻译文如下：

Kernland 国对出口未经加工的腰果征收高额的关税，以保证所有的腰果都被出售给本国的加工企业（农民就赚不到钱了么）。如果提高（？）关税，腰果就会被以全球市场统一价格出售，更多种植腰果的农民就会从种植业中获利。然而，所有的腰果加工企业都在城市，取消关税就会严重的妨碍政府在未来五年内降低城市失业率的努力。

我的问题：这里我就没搞明白，关税和腰果农利润到底是什么关系的？！

怎么提干里面有相反的论述呢？（看我标注的红方黄方）

请大牛指点阿！

关于E的解释是：

典型农民工进城的故事，中国人答不出来不应该。

本来农民种c,但政府不让出口，要的人少，养活不了家里的７，８个女娃，只好进城去c的加工工厂了。现在形式转好，工厂倒闭后就回家种地了，老婆孩子热炕头，又能通过出口ｃ赚取外汇，谁会在城里晃悠呢。所以工厂倒闭了也不会增加失业人口，因为都回家了。

超级不明白的啊！！！

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.

这里说的是城市的失业率哦.

这个关税和我们理解的不同,是"负"关税,就是这个N国内比国际便宜,所以政府为了照顾国内加工N的工厂,就对出口征收"负"关税,从而使得N在国际上没有竞争力.但这么做,less farmers could profit by growing cashews.  所以他们"可能"跑到城市里,从而增加城市的失业率,这是典型的解决老问题,又有新问题类型.

我不明白题干

不过现在明白了 对不起 误导大家拉

If the tariff were lifted

意思是说：如果关税取消的话。。。

单词不认识，真丢人拉
