It is crucially important to farmers that the herbicides they use tocontrol weeds not damage their crops. One very effective herbicide is safe forcorn, but soybeans are damaged even by the herbicide’s residue, which remainsin the soil more than a year after the herbicide is applied. Soybeans and cornare not sown together in the same filed; nevertheless, most farmers arereluctant to use the herbicide on their corn.
Which of thefollowing, if true, provides the strongest justification for the farmers’reluctance?
A.   The residue of the herbicide in the soil a year after applicationis not enough to control most weeds effectively.
B.    To maintain the nutrients in thesoil, corn and soybeans are often planted in a field in alternate years.
C.   The demand for soybeans is growing faster than is the demand forcorn.
D.   For maximum yield, soybean plants are grown closer together to eachother than are corn plants.
E.   The application of herbicides is less critical for soybean than forcorn crops.
中文是說:有一個是除草劑對玉米有效，對棉花無效，這種效果超過一年以上。問strengthen
正確解答是Ｂ:玉米和棉花在同一區域每年輪流種植。

我疑問的是，題目中有一句：＂ Soybeans and cornare not sown together in the same filed＂，
意思是說不能一起種在一塊田裡。
那這樣不就和答案是違背的嗎？

有人可以協助解答嗎？

Thank you~明天就考了...

种大豆的时候地里就不种玉米，种玉米的时候地里就不种大豆，所以大豆和玉米不是“together"播种在同一块田里的。
