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?
請問一下 題目是說: cost: modified seed >> ordinary seed
且 the amount of insecticide 對於modified seed只是稍微少一點點
所以題目結論說: modified seed unlikely to benefit
A. Whether farmers who tried the modified cotton seed had ever tried growing
other crops from genetically modified seed.
"had tried" growing "other crops" 時間+跳脫範圍 刪
B. Whether the insecticides typically used on ordinary cotton tend to be more
expensive than insecticides typically used on other crops.
B是正解 可是我覺得是無關比較阿(other crops)?????
C. Whether for most farms who grow cotton it is their primary crop
補充無關事實 刪
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.
無關比較
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.
最後說 殺蟲劑用量異常的高 則成本高 所以反駁結論
我覺得好像很合理 請問是哪裡想錯了
謝
