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?

(A) The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb. >> Strengthens
(B) Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops. >> Weakens. If this pesticide helps restore the level of cotton production to the earlier level, then price of cotton will also gets restored to earlier level. Thus, farmers planning to switch to cotton (from soy) will not be able to get the 'high prices' for cotton that they are expecting.
(C) In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton. >> Doesn't affect the conclusion
(D) Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying. >> Doesn't matter as long as they are willing to what they are paying now.
(E) The species of insect that has infested cotton plants has never been known to attack soybean plants. >> Irrelevant
