Which of the following most logically completes the argument below?

Davison River farmers are currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profitable. Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Therefore, planting spring wheat will be more profitable than planting winter wheat, since‗‗‗‗‗‗.

A. the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices
B. new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested
C. the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region
D. spring wheat has uses that are different from those of winter wheat
E. planting spring wheat is more profitable than planting certain other crops, such as rye
ANS: A

我想是:春麥跟冬麥有不同的用途吧!

[dibert8]

選到 (C) 咧!
(A) 似乎放諸四海皆準,但是沒有說春麥的情形,這樣能保證春天種春麥比較好嗎?
(C) 春麥適應土壤(雖然限水),應該收成好過冬麥吧?
這樣的思路有什麼問題嗎?

可是我覺得(C)是無關選項耶

因為新政府的限水政策(而且限水只針對冬麥)
Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average.

答案(A)：
即使冬麥的價格較高
但是收成面積較小
結果利潤還是會比種春麥低
(Profit=Price*Q，當Q減少幅度大過Price上升的幅度，Profit還是會下降)

(C)雖然春麥適應土壤的能力好
但是題目前提說兩種麥子獲益力一樣好
(Winter wheat and spring wheat are usually about equally profitable.)
更何況，(C)沒有說冬麥的適應力比較差還是比較好

啊!原來是跟題目牴觸了.
好見解!

題幹問的是獲利相關的問題
就給它一個跟錢相關的選項吧

只有(A)能滿足

感覺作答法......
