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? - Some of the by-products of processing cashews are used for manufacturing paints 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.
这题答案给的是E。小妹愚见，这个E只是说缺少利润使得很多农民离开了他们的土地而去了城市，但这并不能weaken政府的担心--取消了关税以后，乡镇的就业率就不会下降了。盼指点
In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent. In contrast, in the year prior to the tax increase, sales had fallen one percent. The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes. The argument above requires which of following assumptions? - During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
- The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
- The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
- For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
- As the after-tax price of a pack of cigarettes rises, the pretax price also rises.
