    What does the hamburger say about our modern food economy? A lot, actually. Over the past several years Waldo Jaquith intended to make a hamburger from scratch, to no avail. "Further reflection revealed that it’s quite impractical—【C1】________ impossible—to make a hamburger from scratch," he writes. "Tomatoes are in season in the late summer. Lettuce is in season in spring and fall. Large mammals are【C2】________ in early winter. The process of making such a burger would take nearly a year and would inherently involve omitting some core hamburger ingredients."
    That the hamburger—our delicious and comforting everyman food—didn’t【C3】________ 100 years ago is a greasy, shiny example of all that is both right and wrong with our modern food economy. Thanks to fertilizers, genetically modified crops, concentrated farming operations and global overnight shipping, much of the world was lifted out of starvation【C4】________ it could finally grow【C5】________ quantities of food with decreasing labor input.
    But these same【C6】________ that allow food to be grown out of season and in all corners of the globe contribute to a whole host of environmental【C7】________. The "industrialization of food," as author Paul Roberts puts it, is an endless cycle driven by very small price【C8】________ that force food processors to adopt more advanced techniques to produce even more food at lower prices. This system will only be aggravated as food demand increases. Recently David Tilman and Jason Hill of the University of Minnesota released a study【C9】________ that global food demand could double by 2050. It’s【C10】________ that our current, impractical food economy can sustain that demand.
【C5】
选项
答案A
解析 此处需填入形容词，修饰粮食产量。根据out of starvation(免于挨饿)，选择sufficient“充足的”。large可说明量多，但很难说明是否足以消除饥饿，因此不选。
