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??????.

1. the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices
   

   
   

2. new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested
   

   
   

3. the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region
   

   
   

4. spring wheat has uses that are different from those of winter wheat
   

   
   

5. planting spring wheat is more profitable than planting certain other crops, such as rye  这题没人讨论过，想来只是我太弱了，大家选什么呀。

这道题应该选A。

你的问题是什么呀？

题干说：种冬麦和夏麦一样有利可图。目前由于政府的一个新的限制，限制对冬麦的灌溉，而

不限制对夏麦的灌溉。所以种夏麦更有利，因为——

A，冬麦的减产不能被价格的升高带来的收入弥补，也就是无利可图（进一步支持原文）

B，夏麦必须早点种植（无关）

C，夏麦更适合土壤，那么就一定可以带来利润吗？

D，无关比较，并没有涉及到利润

E，out of scope，文章没有提到rye

不知道说明白没有，请指正！

如何排除B选项？

如果种植冬小麦，就没法种植春小麦，因为田地里的冬小麦尚未收割，所以不能种植冬小麦。

b哪里错了？
