Kernland imposes a high tariff on the export of unprocessed cashew nuts
in order to ensure 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 plnts 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 cashew 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.
