标题: 求教大家，一道GWD TN的逻辑试题

Scientists have made genetic modifications to cotton to increaseits resistance to insect pests. According to farmers’ report, the amount ofinsecticide needed per acre to control insect pests was only slightly lower forthose who tried the modified seed than for those who did not. Therefore, sincethe modified seed costs more than ordinary seed without producing yields ofhigher market value, switching to the modified seed would be unlikely tobenefit most cotton farmers economically.

Which of the following would it be most useful to know in order toevaluate the argument?

A. Whether farmers who tried the modifiedcotton seed had ever tried growing other crops from genetically modified seed.

B. Whether the insecticides typically used onordinary cotton tend to be more expensive than insecticides typically used onother crops.

C. Whether for most farms who grow cotton itis their primary crop

D. Whether the farmers who have tried themodified seed planted as many acres of cotton, on average, as farmers using theordinary seed did.

E. Whether most of the farmers who tried themodified seed did so because they had previously had to use exceptionally largequantities of insecticide.
