问题 The United States calls for some countries to research the bionics since 1960.
SAGE needs a mechanical frog’s eye to separate the important details from the unimportant ones picked up by its international network of radar "eyes".
选项 A、Y
B、N
C、NG
答案A
解析 第五段倒数第一、二句话指出"Its international network of radar ’EYES’ supplies a tremendous mass of unimportant details…build a mechanical frog’s eye into SAGE…"需要能够区分重要与非重要的细节的雷达装置植入一只机械青蛙眼，由此可知题干是符合原文的。
