company, whose research was based on
company, which researched
company, in its research of
company’s research, having been based on
company’s research on
这个题中关于having been done的问题,其实只要翻译一下选项就可以很轻松的看出D选项的问题。D的意思是:不像auto 公司的研究是基于crash的,保险公司的研究则考虑了更多东西。E则是,不像auto对crash的研究,保险公司的研究考虑了更多的东西。
在D当中,你要考虑更多因素,怎么可能研究的基础还不同呢?这明显是不合逻辑的。而E就很好的解决了这个矛盾,并且其逻辑更加合理。
