问题     Genetically modified(GM)foodstuffs are here to stay. That’ s not to say that food produced by【C1】______agriculture will disappear, but simply that food buying patterns will polarize.

It’ s not just a question of more mouths to feed either. What is often forgotten is that all these extra people will take up space, reducing the overall land【C6】______for agriculture.
    It may well be that in the long term it is the developing world that benefits most from GM foods. It’s true that for the next ten years or so GM crops may be too expensive. But the lesson of personal computers is applicable here—once the technology has been developed for money-spinning crops,【C7】______maize, soy beans and cotton, it will become【C8】______for all.

A)predicted B)common C)conventional D)like
E)available F)disappear G)purpose H)depression
I)improved J)preference K)correlation L)pace
M)pesticide N)affordable O)variety
【C10】
