GWD 20-37

RT.看不懂这个题。

Q37:

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?

1. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
2. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
3. Some people who ate meat regularly in the past are converting to diets that include little or no meat.
4. As meat prices rise, the number of livestock producers is likely to rise again.
5. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

Answer: B

答案是B。不懂是为啥。大家给指点一下~~谢谢~~

这是一道支持题 关键在于读出支持什么 、

根据问题 要支持observers’ expectation 既增大“an immediate short-term decrease in meat prices”的可能性

B 说农民离开行业前会将livestock送往市场 那么价格有可能在短期内下降（因为供应量猛增）等到农民离开之后价格可能会回升 符合 short-term 的观点

CD有迷惑性 C说明价格可能会下降 D说明供应量会上升 方向都对了 但是没有符合 short-term 的观点 支持的强度不如B

E说明农民的成本可能降低 没有支持observers’ expectation     A为无关选项

祝好运！

同意楼上的答复，围绕价格的问题，主要针对供应与需求展开，实际上，大家如果不约而同地将未出栏的牲口销往市场，长期的供应会在短期内释放，使得市场短期内的价格下降。而后期的供应在前期提前透支，势必导致后期的产品价格提高。这在经济学上无论什么产品都是解释的通的。

不过个人而言，这道题不够严谨，消费者的需求应该远远超过供应，才会对价格产生影响，但这已超出GMAT范畴，毕竟考的是豆芽文嘛！

这道题我这里的答案是E,我也认为是E,到底是什么？那位高手告诉我一下？谢谢啦
