求救一道CR题

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?

A. Some of the by-products of processing cashews are used for manufacturing paints
and plastics.

B. Other countries in which cashews are processed subsidize their processing plants.

C. More people in Kernland are engaged in farming cashews than in processing them.

D. Buying unprocessed cashews at lower than world market prices enables cashew
processors in Kernland to sell processed nuts at competitive prices.

E. A lack of profitable crops is driving an increasing number of small farmers in
Kernland off their land and into the cities.

答案为E
但我很想知道C为何不对？
政府计划征收高关税=》产品内销=》增加国内城区加工就业人数
降低关税=》产品外销=》农民获利
政府计划未来5年降低城区失业率
C农村农民人数大于城区加工业人数，如果征收高关税，农民将会大量失业(该死，政府只管城区，不管农村啊！)
E如果征收高关税，将会有不断增加的农村人口涌入城市，提高失业率  （weaken arguement）
这道题感觉C比较容易诱惑，但是刚才写出了CR链后，发现政府是只管城区，不管农村啊

我试着分析一下哈～

argument关键词是reduce urban unemployment

A. Some of the by-products of processing cashews are used for manufacturing paints
and plastics.
无关
B. Other countries in which cashews are processed subsidize their processing plants.
和reduce urban unemployment无关
C. More people in Kernland are engaged in farming cashews than in processing them.
题目说urban大部分都是processing 所以这个和reduce urban unemployment无关
D. Buying unprocessed cashews at lower than world market prices enables cashew
processors in Kernland to sell processed nuts at competitive prices.
无关
E. A lack of profitable crops is driving an increasing number of small farmers in
Kernland off their land and into the cities.
