题目解析:
这道题目是推断类题型,定位词是biographers 传记作者,根据关键词还原定位:“But—unlike the authors of so many biographies—they hardly ever wrote in order to deceive posterity; hence, archival evidence has an unusual degree of authenticity.” 这句话将行政文件的作者与传记作者进行了对比。They 还原原文指的是archival evidence ,和传记写作者不同,行政文件不是为了欺骗后代,archival evidence 更具真实性;反向推断,传记写作者撰写的信息可能为了欺骗后代而编撰部分信息misrepresented the facts in their writings。因此,A选项正确。
