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

P：新种子要的农药至少一点 + 新种子成本高&不会更高产
C：换到新种子不划算




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.


P：用更少的杀虫剂，用户喜欢
C：新种子将成为趋势
Support：去除他因；D

"The panic touched off by Orson Welles’s 1938 radio broadcast of the science-fiction classic War of the Worlds has often been 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."

C：sicfi -> panic

Weaken：：直接打破因果关系：无sicfi -> panic

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

评估题：

F：genetic modifications to cotton to increase its resistance to insect pests

P：modified seed每公顷用的杀虫剂比寻常种子用的杀虫剂少——modified seed costs more ，no higher market value

C：switching to the modified seed 不咋盈利

总共成本是杀虫剂的成本+seed的成本

正选D：

这个是说两个的样本数量相当，排除两者之间的用量差异是因为误差引起的。如果
一种种了一亩，另一个十亩，一亩的平均数准确率就低很多。

F：vegetable seeds resistant to insect damage

P：cost more but likely to decline；use far less pesticide and consumers prefer

C：their use become the norm

正选D：注意 significantly lower，太小众（供给太少的产品——norm的概率低）
