选E
ABC选项：company和research比较对象不可比。
D选项：比较对象虽然是对等的，但是having been based on crashes在本选项中更像是一个伴随状语，用来修饰整个题目的主句。这显然是不符合逻辑的，该部分在逻辑上应修饰company。
E选项：正确。

having been based on 这个结构放在两个名词中间，容易造成修饰歧义，是修饰前面的名词呢还是后面的名词呢

这道题的比较对象应该是automobile company' research 和 后面 insurance company的research，research on 表达没问题，意思是“关于...的研究”

GMATCLUB解释更合理 Answer (E) makes clear that the research on sport utility vehicles was the auto company’s research. Answer (D), by contrast, introduces a comma and a construction (having been based on) that allows this modifier to refer to the noun before the comma (the auto company’s research) or the noun after the comma (the insurance company’s research). Eliminate choice (D) for an ambiguous sentence structure.

D. 1. XXXX, having... ,XXXX，容易造成修饰不清。 伴随状语可修饰主语。 2. having been;having done 强调时态， 即以前怎样，现在怎样，如 Having finished his breakfast, Joy went to play tennis.

这就是很简单的比较对象的问题，根据后面the research，推出前面也应该是company's research

注意未划线部分，后面对象是research，前面对象也要对应的选company's research，所以直接排除A,B,C（以company为对象）。D的表达不简洁，因此E优选

https://gmatclub.com/forum/unlike-the-automobile-company-whose-research-was-based-on-crashes-240773.html#p2030952 【D】 The modifier having verb-ed/ having been verb-ed has a very specific usage. It is used express the first action out of the two actions done in the past. This modifier modifies an action by presenting another action performed by a noun entity. The action denoted by the having modifier presents the action done prior to the modified action denoted by the verb associated with the noun. For example: Having finished his breakfast, Joy went to play tennis.. In the above-mentioned sentence, the highlighted modifier modifies the following clause. The sentence means that Joy first finished his breakfast and then went to play tennis. Now let's see how this modifier has been used in Choice D: company's research, having been based on Clearly, this modifier has not been used correctly in the sentence. The modifier having been based on modifies the preceding noun the automobile company's research. Choice D seems to suggest that the first the research was based on something, and then something else was done with it. However, this after action is not mentioned in the sentence for the obvious reason that no such information is intended to be conveyed by the original sentence.
