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.
Ans:B
題目是說由於對玉米的需求增加所以其價格上漲並且會維持下去
而玉米是家畜的主要飼料 但在該產業利潤是控制的非常緊的
所以預期許多農夫會離開家畜產業
肉類供給將會減少所以價格會上漲
但作者預期肉類價格在短期會下跌 要找原因支持
答案B我不知該如何解釋
但我覺得DE應該都可以支持啊
D=>肉類價格上漲=>利潤增加=>農夫變多=>肉類產量增加=>價格下跌
E=>農夫加強使用其他的飼料代替玉米,表示玉米價格對農夫的影響沒那麼大,就不會有文章後面的問題產生了啊?自然不會推導出肉類價格將上漲的結論....
請大大幫我解惑
我的思路哪裡出現問題了
