GWD-10-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?

 

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

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.

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

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

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

答案是选B么？

应该是B

答案是B。原文说因为害虫袭击导致棉花产量下降进而导致价格上升。如果新的不昂贵的杀虫剂可以杀死这些害虫，那产量就会上升，价格就会下降。这样growers想take advantage of the high price的计划就泡汤了。因此选B。

但是C也可以削弱啊，因为没有sharp increase demand，所以农民种了以后就会使supply 更多，价格下降啊，那么这么一来不就阻碍了他们take advantage of high price of cotton的设想了吗？请大侠给解答下啊

C不行。

因为前提是：Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton。棉花产量减少而需求没有被减少。因此如果此时增产就可以赚钱。
