Plant scientists have been able togenetically engineer vegetable seeds to produce crops that are highly resistantto insect damage. Although these seeds currently cost more than conventionalseeds, their cost is likely to decline.Moreover, farmers planting them can usefar less pesticide, and most consumersprefer vegetables grown with less pesticide, therefore, for crops for whichthese 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 argumentabove?
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…
A. Whether plant scientists havedeveloped insect-resistant seeds for every crop that is currently growncommercially
irrelated
B. Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage.
Irrelated
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
C. Whether plants grown from the newgenetically engineered seeds can be keptcompletely free of insect damage.
Irrelated
D. Whether seeds genetically engineered toproduce insect-resistant crops generate significantly lower per acre cropyields than do currently used seeds.
E. Whether most varieties of crops currently grown commercially have greater natural resistance toinsect damage than did similar varieties in the past.
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。。。。
Scientists have made genetic modifications to cotton toincrease its resistance to insect pests.According to farmers" report, theamount of insecticide needed per acre to control insect pests was only slightlylower for those who tried the modified seed than for those who didnot.Therefore, since the modified seed costs more than ordinary seed withoutproducing yields of higher market value, switching to the modified seed wouldbe unlikely to benefit most cotton farmers economically.
Which ofthe following would it be most useful to know in order to evaluate theargument?
Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed
Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops[争议 BE]
Whether for most farmers who grow cotton it is their primary crop
Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did
Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide

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
