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?
Some of the by-products of processing cashews are used for manufacturing plants and plastics
Other countries in which cashews are processed subsidize their processing plants
More people in kernland are engaged in farming cashews than in processing them
Buying unprocessed cashews at lower than world market prices enables cashew processors in kernland to sell processed nuts at competitive prices
A lack of profitable crops is driving an increasing number of small farmers in kernland off their land and into the cities

Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted.This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job.On the contrary, since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base.The high success rate shows insufficient canvassing effort.
Which of the following, if true, provides more support for the argument?
Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.
This year the average size of the donations to Smithtown University from new donors when the university’s fund-raisers had contacted was larger than the average size of donations from donors who had given to the university before.
This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the university’s fund-raisers having made any contact with the donors.
The majority of the donations that fund-raisers succeeded in getting for Smithtown University this year were from donors who had never given to the university before.
More than half of the money raised by Smithtown University’s fund-raisers came from donors who had never previously donated to the university.
I donot understand why the key is A? My initial answer was C, but now I understand why C is not correct. How do you reason to sort A out?
