By saying "no document is safe any more", the author probably means ______.
What lies at the core of both old and new ways of anti-faking is ______.
选项
A、the quirks of the keys of the typewriters
B、the drums and mirrors of the printers
C、the subtle defects of printing devices
D、the special skills of the experts
答案
C
解析
由题干中的the core of both old and new ways of anti-faking定位到原文第二段第一、二句His approach is based on detecting imperfections in the print quality of documents.Old-school court scientists were able to trace documents to particular typewriters based on quirks of the individual keys.[精析] 事实细节题[考频:51]。原文第二段第一句就说,他的方法建立在检测文件打印质量的瑕疵上,然后下文接着说,老式的方法主要靠打字机键盘的特定字体弯曲来追踪文件,又说他的方法与老式的相似,利用打印机内部的滚筒和磁镜设计方面有瑕疵的事实来追踪文件。因此可以推断新旧两种方式的共同核心在于印刷设备的细微缺陷。故C)与之相符,为正确答案。[避错] A)“打字机键盘的特定字体弯曲”是老方法的依据,排除;B)“打印机内部的滚筒和磁镜”不具体,原文指“打印机内部的滚筒和磁镜存在工程学的瑕疵”,排除;D)“专家的特殊技巧”在原文没有提及,故排除。
