Passage2
The International Coffee Agreement(ica) was set up in1963 to try to stop the downward drift of prices, and to "stabilize prices above their free market level. "It did this by regulating the supply of coffee beans coming on to the world market. Producing countries each agreed to export a "quota", a certain quantity of coffee, which was a little less than they would have normally exported without controls. By exporting slightly less than they might have done, the producing countries received a higher price per bag-and their overall revenues were higher. When coffee prices rose, producing countries were allowed an increase in their quotas, when prices fell their quotas decreased.
The agreement managed the market in a modest way but its biggest problem was that a timebomb(定时炸弹) markedoverproductionwas persistently ticking away underneath it-and finally exploded. Coffee producers had constrained their exports but not their output. This led to a huge build-up of stocks that countries could not sell, and it was clear that when the agreement ended, many of the stocks would be released on to the world market and the price would plummet.
The United States wanted larger quotas to be given to the producers of the higher quality Arabica coflees. And like other importing countries it wanted action to end the black market in international coffee trade, whereby countries traded their surplus unofficially, at a price sometimes only half that of the official world market price; half-price was thought better than dumping coffee beans in the sea or letting them rot.
50.The quotas can be adjusted according to the world coffee market prices
A、True
B、False
【正确答案】：A
【名师解析】:根据文章内容，国际咖啡协议（ICA）通过控制咖啡豆的供应来稳定价格，其中提到了当咖啡价格上涨时，生产国的配额可以增加；当价格下跌时，配额可以减少。这表明配额确实是根据世界咖啡市场价格进行调整的。因此，选项A "True" 是正确的。
