问题 According to the Oxfam report, the next 20 years will see ______ percent increase in the need for food.
  
An international aid group is calling for an overhaul of the world’s food system, saying prices for staples such as corn will double in the next 20 years. London-based Oxfam released a report Tuesday saying demand for food is expected to rise 70 percent by 2030, as climate change, lower crop yields and rising energy prices pressure food supplies.
    The group says those hardest hit will be the poor, who spend as much as 80 percent of their income on food. The report recommends addressing the problem by boosting food reserves, ending the use of food crops in biofuels, and ending speculation in worldwide food markets. It also calls for a shift away from large-scale commercial food producers to smaller local growers.

选项 A、increasing the stock for food.
B、adjusting the food production scale.
C、cultivating more lands to grow.
D、halting profiteering in the food market.

答案C

解析 细节判断题。新闻中指出,为了解决粮食需求、控制价格猛涨的局面,可以增加粮食储备、结束将粮食作物用作生物燃料以及停止世界粮食市场的投机买卖行为.还可以从大规模生产商品粮转型为地方上的小规模种植。选项A、B、D与新闻内容相符,本题要求选出与新闻报道不相符的一项,所以答案是C。
