Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers' report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically.
Which of the following would it be most useful to know in order to evaluate the argument?
Plant scientists have been able to genetically engineer vegetable seeds to produce crops that are highly resistant to insect damage. Although these seeds currently cost more than conventional seeds, their cost is likely to decline. Moreover, farmers planting them can use far less pesticide, and most consumers prefer vegetables grown with less pesticide, therefore, for crops for which these seeds can be developed, their use is likely to become the norm. Which of the following would be most useful to know in evaluating the argument above?
A. Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage. C. Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage. D. Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds. E. Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past.

请问一下各位NN,能不能麻烦分析一下这道evaluation的premise和conclusion?总感觉在B、D之间有点迷惑! Thx in advance!

Bg: Plant scientists havebeen able to genetically engineer vegetable seeds to produce crops that arehighly resistant to insect damage. Counterpromise: Althoughthese seeds currently cost more than conventional seeds, their cost is likely to decline. Additional promise: Moreover,farmers planting them can use far lesspesticide, and most consumers prefervegetables grown with less pesticide, Conclusion: therefore,for crops for which these seeds can be developed, their use is likely to become the norm.
We know that new cropshave many advantages, so they are likely to become norm. So we have to find adisadvantage of new crops…

When we answeryes it supports. When we answer no it doesn’tweaken…
对比下这两个。。。- - 也许这就是为什么大家都说逻辑JJ是把双刃剑吧。。。。

69. Scientists have modified feed corn genetically, increasing its resistanceto insect pests. Farmers who tried out the genetically modified corn lastseason applied less insecticide to their corn fields and still got yields comparableto those they would have gotten with ordinary corn. Ordinary corn seed,however, costs less, and what these farmers saved on insecticide rarelyexceeded their extra costs for seed. Therefore, for most feed-corn farmers, switchingto genetically modified seed would be unlikely to increase profits. Which of the following would it be most useful to know in order to evaluate theargument? (A) Whether there are insect pests that sometimes reduce feed-corn yields, butagainst which commonly used insecticides and the genetic modification are equally ineffective (B) Whether the price that farmers receive for feed corn has remained steadyover the past few years (C) Whether the insecticides typically used on feed corn tend to be moreexpensive than insecticides typically used on other crops (D) Whether most of the farmers who tried thegenetically modified corn last season applied more insecticide than wasactually necessary (E) Whether, for most farmers who plant feed corn, it is their most profi tablecrop Argument Evaluation
哇哇哇~~谢谢上邪~~~你的回答好满意啊!我做的时候也是记着这两题,但是翻了一下没找到。 “teddy你之所以觉得B分不清楚是因为你清楚的记得下面的两道题 可是抛开那两道题你再体会这个promise---conclusion的关系 因为有优点 所以使用普遍。。如果我们要削弱使用普遍 那么就要找一个缺点出来 而B所讲的就与这个逻辑链毫无关系了the issue whether farmers use pesticides in large amounts doesn't matter at all。。。就算我过度使用了 并不影响使得我新crops普遍使用的优点”
上面的第二题的“终结者”分析是正确的,但是E里面也并没有提到关于这么一点amount减少的杀虫剂的量的cost与成本的cost差相比那个大,反而是B,只要 other crops包含genetic modified cotton,那就正好解释了您的思路,因为之前使用杀虫剂比现在使用的贵很多,所以虽然现在量只减少了一点点,但是足以抵消成本的cost差,BE的争议到此结束。
