We can infer from this passage that GM foods_________A、are banned by the American government
B、have scared away most American consumers
C、have already arrived on American dinner tables
D、are welcomed by more and more American people
【正确答案】：C
【题目解析】： 判断推理题。文章在介绍了美国议会通过的禁止各州强制要求贴转基因食品标识之后，又介绍了美国民众对转基因食物标识的态度。最后得出结论We didn't find evidence that thelabels will work as a warning（没有证据证明这样的标识能起到警告作用）。由此可以推断，美国人虽然看到这样的标识仍然会买转基因食品。C选项的内容符合文意。因此选项C为正确答案。
