Escalating worldwide demand for corn is expected to cause the market price of corn to rise sharply and remain high. Although corn is extensively used as feed for livestock, livestock feed accounts for only a small fraction of the retail price of meat. Therefore, the increase in corn prices is very unlikely to produce any comparable long-term increase in the retail price of meat.

Which of the following, if true, most seriously weakens the argument?
A The cost of shipping and handling meat has also risen sharply.
B Livestock producers who currently use corn to feed their livestock have the option of switching to other kinds of feed.
C The rising cost of feed is leading some livestock producers to leave the business, thereby reducing the future supply of meat.
D Worldwide demand for grains other than corn has also increased.
E The price of corn affects the retail price of a variety of other food products more than it affects the price of meat.

为什么选C啊，不太懂，大家都不养livestock哦，那么肉的需求就减少，需求减少价格会上升？？？？

C答案的意思是大家不养livestock减少了肉的供应，潜台词是肉的价格会提高

不养说明肉没那么多消耗了么，没人买了，价格应该会降低啊

果子cx

应该是物以稀为贵吧 供应少了 需求不变或增加的话 价格会上升

C选项说的不是对肉的需求少了，而是由于成本升高， livestock producers 会 leave the business，供给少了， 那么自然价格就提高了。
