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.

Answer: B

可是我觉得应该是C

我认为是B,因为涨价是虫引起的,现在有了好的杀虫剂,那么虫的影响没了,价钱就要下来了。C是无关内容。
把所有的困苦都看做是有意义的,是生命对你的磨练,也许,是为了让你成大事而做准备。

想通了,C确实是无关选项。谢谢Sammen
