问题 Before DNA fingerprinting is used, suspects ______. [br] The National Academy of Sciences holds the stance that ______.
选项 A、DNA testing should be systematized
B、only authorized laboratories can conduct DNA testing
C、the academy only is authorized to work out standards for testing
D、the academy has the right to accredit laboratories for DNA testing
答案 B
解析 国家科学院的立场要参看文章最后一句话：And in April，the National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories．(四月份时，国家科学院要求DNA检测实验室建立严格的标准和鉴定合格体系)，由此可知，他们的立场便是只有权威试验室才能进行 DNA检测。B表达的意思与原文相符，故为答案。选项A. “DNA测试应系统化”与文意不符。
