Unlike the automobile company, whose research was based on crashes involving sport utility vehicles, the research conducted by the insurance company took into account such factors as a driver’s age, sex, and previous driving record.
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
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。
会引起歧义
会引起歧义
C选项having been based on是伴随状语，修饰最近的动作，最近的动作为took into account 主语为the research conducted by the insurance company 。显然是不合理的，因为这个having been based on逻辑上是企图描述前方的 the automobile company’s research
E选项正确
比较对象对等
Unlike A, who do B, C do D.这个结构里通常要求do B和do C构成unlike的点。
A，Unlike the automobile company‘s research, based on crashes, the research took into account such factors as a driver’s age, sex, and previous driving record.
研究考虑司机的年龄、性别、驾驶记录与研究建立在碰撞的基础上没法unlike，要unlike的话是：另一家公司将研究建立在B基础上。
而且从常识理解，他们为啥考虑司机的年龄、性别、驾驶记录？为了研究。所以改成unlike the research on crashes，关于碰撞的研究，ok
D，having been based on表示先时性，不像A的研究，已经以撞车为基础，B的研究考虑了其他的。
E，不像A的关于汽车碰撞的研究，B的研究考虑了其他的。ok
同时，紧跟名词的comma+ing除了可以做定语修饰名词，还有充当伴随状语的歧义。
D：having been based on VS based on
