11.. GWD7-Q37:（CD-5-37）
Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high.Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business.With fewer suppliers, meat prices will surely rise.Nonetheless, observers expect an immediate short-term decrease in meat prices.

Which of the following, if true, most helps to justify the observers’ expectation?

A.The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.

B.Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.

C.Some people who ate meat regularly in the past are converting to diets that include little or no meat.

D.As meat prices rise, the number of livestock producers is likely to rise again.

E.Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.


答案选B，但我认为B和C都对。我是这样理解的。
B中被挤出市场的农民很早就把牛卖到市场上，暂时性供给增加，价格下降
但C说的是需求减少也就是说供给太多，所以价格会下降。
 不太懂，求大牛们指点~

an immediate short-term decrease 是题眼，你得找一个马上立即短期的上升的价格的举动

首先要注意很多题目要求你选的是最佳选项。

当然C也是可以解释的，但是要注意C选项说的是some people，而B选项则是generally。B的说服力显然更大。

tips：在逻辑里一些很模糊的词, 如果出现就要注意, 虽然有时侯是正确选项, 但因为这些词比较不具代表性或比较主观, 应引起重视.
概念模糊的词: some, many, certain某些;
主观: willing to, interested, aware.
