问题 The 386 piglets wrongfully sold into food supply are from ______. [br] It can be inferred from this passage that ______.
选项 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
答案 B
解析 推断题。第七段提到，伊利诺伊大学称，每头仔猪都做了八次检验以确保它们没有转基因遗传，若检出带有转基因遗传的则被送回用于研究，由此可推断B正确，即部分仔猪携带母猪的遗传基因。
