2（）| The Food and Drug Administration said
Wednesday that it is trying to track down as many as 386 piglets that may have
been genetically engineered and wrongfully sold into the U.S. food
supply. The focus of the FDA investigation is pigs raised by researchers at the University of Illinois in Urbana Champaign. They engineered the animals with two genes: One is a cow gene that increases milk production in the sow. The other, a synthetic gene, makes the milk easier for piglets to digest. The goal was to raise bigger pigs faster. There has been no evidence that either genetically altered plants or animals actually trigger human illness, but critics warn that potential side effects remain unknown. University officials say their tests showed the piglets were not born with the altered genes, but FDA rules A. all the offspring have their mothers’ genetic engineering B. part of the offspring have their mothers’ genetic engineering C. none of the offspring have their mothers’ genetic engineering D. half of the offspring have their mothers’ genetic engineering [单项选择]石材幕墙的铝合金挂件厚度不应小于（）mm。
