问题 The United States calls for some countries to research the bionics since 1960. [br] The U.S. Rubber Company is making tests of using the elastic skin of a dolphin for beats and submarine hulls.
选项 A、Y
B、N
C、NG
答案 B
解析 文章第十一段指出"…the U.S. Rubber Company is making tests of a rubber ’skin’ for boats and submarine hulls，modeled on the elastic skin of a dolphin"．用橡胶“皮”进行测试而不是用弹性好的海豚皮来做测试，题干与原文不符。
