再来一题 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. 这一题我用排除法:由于原文是要weaken the plan that the gower's income will increase,因此必定会有影响income的元素 而且和cotton有关 A 提及到cost irrelevent B 这个应该是support吧 C 无关吧(原文信息中无法推断出过去的信息) D明显会影响收入 correct E无关
