It is crucially important to farmers that the herbicides they use to control weeds not (?) damage their crops. One very effective herbicide is safe for corn, but soybeans are damaged even by the herbicide’s residue, which remains in the soil more than a year after the herbicide is applied. Soybeans and corn are not sown together in the same filed; nevertheless, most farmers are reluctant to use the herbicide on their corn.
Which of the following, if true, provides the strongest justification for the farmers’ reluctance?
A: The residue of the herbicide in the soil a year after application is not enough to control most weeds effectively.
B: To maintain the nutrients in the soil, corn and soybeans are often planted in a field in alternate years.
C: The demand for soybeans is growing faster than is the demand for corn.
D: For maximum yield, soybean plants are grown closer together to each other than are corn plants.
E: The application of herbicides is less critical for soybean than for corn crops...
有人知道这道题选什么不 XDF老师给的A 但是有人说是B
好像是OG有的？？
这道题我记得做到过，选B。
A完全是无关选项可以第一个排除的。题目讨论的是对crops的damage。而A选项只讨论了对weed的持续效果时间。要是xdf的老师真认为选A的话那只能为你花的钱感到可惜了，哈哈。
