{{B}}Questions 57 to 61 are based on the following
passage.{{/B}} Genetically Modified (转基因的) crops are everywhere. It seems even in Europe, strict laws designed to keep the European Union free of GM crops and products are not working, instead are posing problems for the EU: Farmers’ representatives say that supplies of animal feed for poultry and pigs are being refused entry at European ports when found to contain even trace amounts of GM material. Under Europe’s "zero-tolerance" laws on GM, introduced in 2007, the presence of even a few seeds of GM material will rule out an entire shipment. The animal feed industry says that the laws are unworkable because GM material is almost unavoidable, given today’s global supply chain. "Though we understand the consumer concern in Europe, we don’t understand zero tolerance because it closes down trade," says A. GM material is universal B. European laws are impractical C. only the international supply chain can work out D. goods should be prohibited once any GM stuff is found 更多"{{B}}Questions 57 to 61 are based o"的相关试题: [单项选择]
