Day 59
1.        自带杀虫天赋的种子之一
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?
A.Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed
B.Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops
C.Whether for most farmers who grow cotton it is their primary crop
D.Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did
E.Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide

2.        自带杀虫天赋的种子之二
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.

3.        火星人入侵地球啦！

"The panic touched off by Orson Welles’s 1938 radio broadcast of the science-fiction classic War of the Worlds has often been the ascribed to the lingering anxieties of the Depression era and apprehension about the a second world war; political and economic unease supposedly made people psychologically prepared to believe that Earth had been invaded by Martians.

Which of the following, if true, would most seriously weaken the attempt above to explain the panic of 1938?

(A) Film adaptations of War of the Worlds are generally regarded as less realistic than Welles’s radio version.

(B) Rebroadcasts of Welles's War of the Worlds during times of peace and economic optimism have on occasion resulted in similar panics.

(C) The 1898 publication of the novel on which the radiobroadcast of War of the Worlds was based resulted in no public disturbances.

(D) Even after the invasion depicted in the 1938 radio broadcast had been widely publicized as fictitious, some people maintained that they had seen the Martian invaders.

(E) Some people who had not listened to the 1938 radio broadcast were nonetheless caught up in the resulting panic."

DAY 59BDB

1. P: 抗虫棉花所需要的杀虫剂用量只有轻微减少，没有更高的市场价值

C: 不会增加农民收入

评价：1. 是否普通棉花的杀虫剂牌子更贵，抗虫棉花的杀虫剂牌子便宜，从而降低成本

2.P：抗虫棉花种子在未来价格会下降，使用杀虫剂更少，成本低且消费者更喜欢

C：抗虫作物会变得越来越普遍

评价：这种作物的平均每亩单产量是否会下降

3. 减弱电台节目和恐慌的相关性，另外的相似失败案例削弱

E.Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide
P:科学家给棉花做了一些基因调整去增强其对害虫的抵抗力，但是调整后的那批也只比之前没调整的那批稍微好了一点点
C:所以，花了大价钱去买那调整后的棉花也没啥特别高的市场价值，所以换种这批棉花也对农民没啥经济上的好处，挣不到钱。
思路：评估，该扣结论，一定是要看是不是跟提高农民经济的选项。
A：跟其他的crops有啥关系？
B:跟杀虫剂也没关系啊，要看新的转基因物的经济效益
C：没提经济
D:这里其实提到了样本数量，可能是之前得出的结论缺少新作物样本对比，保留
E:农民的想法无关。

E.Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past.
F:前面都一样，都是转基因物巴拉巴拉，
P:用这种种子可以少使用杀虫剂，而消费者更喜欢这种杀虫剂用得少的蔬菜
C：所以之后越来越多人会用这种种子
思路：评价，感觉要和是不是少用杀虫剂相关，因为只有相关了，消费者买得多，农户才种得多
A：跟这种种子的价钱有关吗？
B:只提之前的种子感觉不太充足
C：感觉这个可以
D：新的种子比之前那种产量更少？嗯。。。也有可能，产量少了，那农户就不种了可能，所以不会变得norm.
E:most有啥用啊，要就要对比之前的的现在的。

3.        火星人入侵地球啦！
1938年，某电台播送了一段蛊惑人心的节目引起了空前panic（恐慌）。当时世界经济处于大萧条时期而且政治上二战爆发在即。结论说电台节目使人们深信earth is invaded by Martian.
问：削弱
A.        说一些没有听广播的人也恐慌了
B.        电台节目是基于一本写于1895年的某fiction改编的。但是fiction本身在当年并没有引起恐慌。
P：由于电视放的节目引起恐慌，恰逢二战在即
C:所以那个节目让人深信火星人要入侵地球了
思路：削弱，可以削弱因果关系哇，提到不是那个节目的原因就可以了
选A，确实，听没听节目的人都恐慌了，那说明不是节目的直接原因。
