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

答案是A。。知道其他的都不对 不用解释了。。
请问A是 winter wheat 已经缩小侯的产量不能弥补winter wheat 的高价。。那岂不是说winterwheat带来的利润更高了吗。。原文说的是springwheat利润高啊。。。？ 还是我理解错了。。

草稿纸

利润不等于价格，gross profit=价格x产量-成本（成本这里不考虑）

也就是说(w低产量 x w高价) < (w 正常产量 x w 正常价格) = (s 正常产量 x s正常价格)

也就是说(w低产量 x w高价) < (w 正常产量 x w 正常价格) = (s 正常产量 x s正常价格)
