GWD10-40

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B  我也选了B  但是我觉得D也说的过去啊

因为文中先是说了虫灾会导致棉花价格的上涨 那如果消费者不愿意去高价买的话 也会weaken 计划的成功啊

可是消费者喜好与价格之间的关系并没有在原文指出，所以这里的陷阱是典型的“引入熟悉的陌生第三者outsider”
