试题详情

题目:

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?

选项:

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:

B

提问:

做题时,排除了A,B,E;不沾边;但是很纠结C,D,因为B没有讲到pesticide,最后选了C,请老师指点

提问:

请唐老师用技巧讲一下(不是讲逻辑链), 为什么E被排除? 为什么句子带了"袭击大豆"就不对?一开始的计划是,不种大豆,种棉花... 我的理解是, E也是讲种棉花, 只是多加了一句, 不知昆虫是否袭击大豆. E的表述, 是和计划-不种大豆,种棉花-相关的.

提问:

D为什么排除呢?题干说停止种大豆,开始种棉花会带来收入增加,B和D中都提到了棉花,B说了便宜的杀虫剂,D说了price,所以选B是因为便宜比price与增加收入更有关吗?

您好,这道题目想要请王文静老师来回答一下,我是之前广州班的学生,这个题目我选的是C,题目让我们削弱这个计划,这个计划就是为了提高收入去种棉花,很明显这个B跟这个额计划没有关系了直接就排除了这个B,感谢老师的解答!

提问:

之前问:请老师解释一下E为什么不对?E也讲了昆虫的事情,而且就文章“不种黄豆种棉花”的计划,感觉E的相关性更强一些 老师的解答: 原文逻辑链:弃大豆改种棉花————》显著提高未来几年的收入 B: 有一种治疗棉花虫害的好药出来了 E: 攻击棉花的害虫不攻击大豆 补充提问:我理解的B:有一种好药出来了但不治棉花的害虫,老师的理解是有一种治疗棉花虫害的好药出来了,这样选B反而支持了种棉花的原文;反而E攻击棉花的害虫不攻击大豆起到削弱作用,还是不理解为什么E不行

提问:

这道题,改正思维点能排除错选了。 但是,有一个毛病,就是做题看选项的时候通常很注意结论,但是可有可能把文中的前提给忘了,所以导致觉得不相关。 已经不是第一次遇到这样的问题了,请问老师有什么办法能解决忘记原文前提这一问题吗??谢谢

提问:

做这道题看选项时,每个选项感觉与文章都无关,尤其是B,没有提到pesticide。
