The doctor decided to test the chips himself because he believed that ______.
选项 A、nobody would dare to try it
B、they can be used for identification purposes
C、it has been proved successful on animals
D、his patients expected him to experience it first
答案B
解析 第三段讲到“9.11事件后医生决定对芯片进行测试。因为如果死难者的名字和其他重要信息输入到芯片上，他们的身份就能被辨识了。”所以，医生决定对芯片进行测试是因为相信电脑芯片可用于身份识别。所以[B]为正确答案。
