问题     Not content with its doubtful claim to produce cheap food for our own population, the factory-fanning industry also argues that "hungry nations are benefiting from advances made by the poultry (家禽) industry".  In fact, rather than helping the fight against malnutrition (营养不良) in "hungry nations", the spread of factory fanning has, inevitably aggravated(加重)the problem.
    Large-scale intensive meat and poultry production is a waste of food resources. This is because more protein has to be fed to animals in the form of vegetable matter than can ever be recovered in the form (ff meat. Much of the food value is lost in the animal’s process of digestion and cell replacement. Neither, in the case of chicken, can one eat feathers, blood, feet or head. In all, only about 44% of the live animal fits to be eaten as meat.
    This means one has to feed approximately 9 - 10 times as much food value to the animal as one can consume from the carcass. As a system for feeding the hungry, the effects can prove disastrous. At times of crisis, grain is the food of life.
    Nevertheless, the huge increase in poultry production throughout Asia and Africa continues. Normally  British or US firms are involved. For instance, an American based multinational company(跨国公司)has this year announced its involvement in projects in several African countries. Britain’s largest suppliers  of chickens, Ross Breeders, are also involved in projects all over the world.
    Because such trade is good for exports, Western governments encourage it. In 1979, a firm in Bangladesh  called Phoenix Poultry received a grant to set up a unit of 6,000 chickens and 18,000 laying hens. lifts almost doubled the number of poultry kept in the country all at once.
    But Bangladesh lacks capital, energy and food and has large numbers of unemployed. Such chickenraising  demands capital for building and machinery, extensive use of energy resources for automation(自动化), and involves feeding chickens with potential famine-relief protein food. At present, one of Bangladesh’s main imports is food grains, because the country is unable to grow enough food to feed its population. On what then can they possibly feed the chicken?
According to the author, in factory, vegetable food______.
选项 A、is easy for chickens to digest
B、is insufficient for the needs of poultry
C、is fully utilized in meat and egg production
D、is inefficiently converted into meat and eggs
答案D
解析 细节题。本题问的是：作者认为养殖场的蔬菜______。根据第2段第2句“This is because more protein has to be fed to animals in the form of vegetable matter than can ever be recovered in the form of meat”可知，食物浪费的原因是喂给动物的以蔬菜形式表现的蛋白质在其肉中要流失一部分，因此并未在肉中完全转化，故选D 。
