标题: OG20 求问 为什么我总觉的正确选项是错的 [打印本页] 作者: 1998JIN 时间: 2019-8-1 13:38 标题: OG20 求问 为什么我总觉的正确选项是错的 Supply shortages and signs of growing demand are driving cocoa prices upward.Unusually severe weather in cocoa-producing regions—too much rain in Brazil and too little in West Africa—has limited production. Further, Europe and North America recently reported stronger demand for cocoa. In the first quarter, grinding of cocoa beans—the first stage in processing cocoa for chocolate—rose 8.1 percent in Europe and 16 percent in North America. Analysts have concluded that cocoa's price will continue to rise at least into the near future.
Which of the following would, if true, most strengthen the reasoning above?
A Ground cocoa beans can be stored for long periods before they spoil.
B Several European and North American manufacturers that use cocoa have recently improved their processing capacity.
C It takes new cocoa trees five or six years before they start bearing fruit.
D Governments in Europe and North America are likely to change current restrictions on cocoa imports.
E Historically, cocoa production has varied widely from year to year.
A. Ground cocoa beans can be stored for long periods before they spoil.- Weaken
喔～～有沒有可能有存貨？ 既然有存貨又不會壞掉, 那價格絕對不會“在最近的將來”上升
B. Several European and North American manufacturers that use cocoa have recently improved their processing capacity.- Irrelevant, the processing capacity was not a bottleneck and thus improvement in processing capacity will not help.
C. It takes new cocoa trees five or six years before they start bearing fruit.- Correct, this addresses the issue from supply side. What it means that people cannot increase the production of Cocoa in short notice and thus supply WILL NOT increase
D. Governments in Europe and North America are likely to change current restrictions on cocoa imports. - Irrelevant, we have no idea how strict the current restrictions are. It may be that current restrictions are already very little. Also, we are told that demand and supply factors are driving up the prices.
改變到底是變好還是變不好, 題目沒說, 所以我們不要自己下定論
E. Historically, cocoa production has varied widely from year to year. - Irrelevant
