GWD 11, question 3:

EFT;">Scientistshave made genetic modifications to cotton to increase its resistanceto insect pests. According to farmers’ report, the amount ofinsecticide 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 seedwithout producing yields of higher market value, switching to themodified seed would be unlikely to benefit most cotton farmerseconomically.

EFT;">Whichof the following would it be most useful to know in order to evaluatethe argument?

1. EFT;">Whether    farmers who tried the modified cotton seed had ever tried growing    other crops from genetically modified seed.
   
       
   
2. EFT;">Whether    the insecticides typically used on ordinary cotton tend to be more    expensive than insecticides typically used on other crops.
   
       
   
3. EFT;">Whether    for most farms who grow cotton it is their primary crop
   
       
   
4. EFT;">Whether    the farmers who have tried the modified seed planted as many acres    of cotton, on average, as farmers using the ordinary seed did.
   
       
   
5. EFT;">Whether    most of the farmers who tried the modified seed did so because they    had previously had to use exceptionally large quantities of    insecticide.
   
   
   

The answer key is B. I don't understand... Why do we care about other crops? 想不明白... Thoughts anybody? Thanks!

B肯定不对的，比较下来就觉得E是唯一的靠普点的，
这题好像OG上有类似的，但是选项比这个更好的
