答案是B,但我觉得即便有pesticide，文章里也没说能够非常快的把价格降回来啊。。。大家帮忙看看

GWD-10-Q40

Insect infestations in certain cotton-growing regions of the world have caused dramatic increase 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 being 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?

1. The cost of raising soybeans has increased significantly over the past several year and is expected to continue to climb.

2. 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.

3. In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.

4. Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.

5. The species of insect that has infested cotton plants has never been known to attack soybean plants.

A

这是一道很容易的题目，逻辑链的起源就是 cotton有虫害导致了后面一系列的事情

那么newly developed杀虫剂的出现可以减少虫害

所以就weaken了

太简单了

Insect
infestations in certain cotton-growing regions of the world have caused
dramatic increase 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 being 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?

1. The cost of raising soybeans has increased significantly over the past several year and is expected to continue to climb. ---cost 上升了，不一定income就上升到比cotten高，所以无法削弱
   
2. 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.---害虫多导致价格上升，现在解决了害虫的问题，价格就不会上升了，所以cotten不一定income多，削弱了argument.
3. In the past several years, there has been no sharp increase in the demand for cotton and for goods made out of cotton.---无关，原文是从price的角度分析的
4. Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.---说的是cotten不是cotten  goods，无关
   
5. The species of insect that has infested cotton plants has never been known to attack soybean plants.---这个不能削弱，s不受insect影响，产量不变化，所以价格更加stable，那么选择cotten倒是好了

可是B的话，即便cotton价格不再上升，但现在已经是比原来高很多了，种soybean的人也有理由来种cotton啊。。。
