Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable. Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and begin raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly, at least over the next several years.

Which of the following, if true, most seriously weakens the plan's chances for success?

AThe cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.
BTests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops.
CIn the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.
DFew consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
EThe species of insect that has infested cotton plants has never been known to attack soybean plants.

正确答案: B

大家是不是都忽略了B里面是说In the PAST several years.讲过去的事情和未来的prediction有什么关系啊...
另外想问A选项，我知道是基于第一句话，但是有虫害--》有价格提升不等于无虫害--》无价格提升吧？,有了杀虫剂，不一定价格就会跌吧？从原文infer不出来啊...
