标题: 请教一道GWD31的题目，在汇总里没有找到

我的是GWD31第一套的40题，找不到，不知道我的材料是不是不一样啊

题目是

Q40:

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?

The cost of raising soybeans has increased significantly over the past several years and is expected to continue to climb.
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.
In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.
Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.
The species of insect that has infested cotton plants has never been known to attack soybean plants.

我想问一下D为什么不对，谢谢。

D说顾客们不愿意付比现在高的价格去买cotton，但是如果他们愿意花和现在一样高的价格去买cotton，种植者们就有利可图了，所以，这个不能算weaken.

是不是B是肯定的事实，而D只是可能而不是肯定的所以不选？

谢谢，呵呵
