Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market.Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans, the price of which has long been stable, and to 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 calls into question the reasoning on which the plan is based?

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 infected 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. Many consumers consider cotton cloth a necessity rather than a luxury and would be willing to pay significantly higher prices for cotton goods than they currently pay.

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



结论：taking advantage of the high price of cotton to increase their income significantly at least over the next several years.

看到有人的解释
B选项：一种不贵有效且又环境安全的农药问世了。就削弱的cotton高价的优势；
觉得逻辑很牵强
C选项：没棉花的需求没有增加，但是种植量增加，从供需关系上讲，将会使价格下降，从而削弱结论

我觉得逻辑关系上来讲C更合理，

请NN过来指教！！！

我的理解是，根据题干  供给减少了，即使需求不增加，价格也会上升。

题干不是说cease growing soybean,began to raising cotton instead吗？供给明显是增加，怎么会是减少呢？

tkcamfan

害虫入侵棉花地迫棉花价格上升（这里就是说棉花的供给减少了），cease growing soybean,began to raising cotton instead是说他们准备停止种黄豆，转而种棉花

这些日子，他成了心底的隐痛，挥之不去。异火丹师离去的背影装满忧伤。这么多年以来，他眼睛里的哀怨和伤情一直留在我心里，偶尔想起，想起流氓高手II的他为我打架，头破血流的样子，感到一阵心悸，有痛的感觉。这次意外重逢，我的心忽然猛烈的跳了起来。他的两鬓竟然有了灵武九天的白发，额头和眼角的皱纹层层叠叠，眼睛多了沧桑，一种令几乎可以令人笑傲华夏的沧桑。我们相对无言，不知道从哪里开口，身边人来人往，没有人知道我和他曾经有过一段故事，一段关于青春的故事。在邪龙道意外相遇的几十分钟，我和他加起来说的话不到十句，听到的都是扑通扑通的心跳，他转身离去的时候，我莫名其妙地想哭。他走了，像十几年前一样。那时候，我恶狠狠地催他走，让他永远都不要来找我要神印王座，让他永远忘记我。当时他一步三回头，噙着泪水黄龙真人异界游，那个场景至今仍然历历在目。如今，他和从前一样离去，只是他没有回头，没有多看我一眼。如今只能纯阳仙境，将沧桑的脸在今晚被我写进了文字里……
