AjiteshArun sir,

How is "in its research" in option C ambiguous?
After "in its research", the main clause starts with "research", not with Insurance Company.
If Insurance Company would have been there, then this phrase could be ambiguous.

Furthermore, in option A isn't the usage of "whose" incorrect? Who/Whose can only be used for living things.

Please evaluate where am I going wrong.

Thanks

Hi krndatta,

We can read the sentence option C leads to like this:
1. {Unlike the automobile company, in its research of crashes involving sport utility vehicles}, the research...

or like this:
2. Unlike the automobile company, {in its research of crashes involving sport utility vehicles, the research...}

The main reason to remove both A and C, of course, is the (incorrect) comparison (the automobile company/the research conducted by the insurance company).

As for whose, it can be used to refer to pretty much anything. That is, we can say something like "the question, whose difficulty level was not known".

Show more

Two different reasons.

1/ "Having been __ed" describes something that occurred in the past that has some kind of impact on the present situation. E.g., Having been harassed in the city's main park, Smith was loath to return there.

2/ When a comma-separated __ING modifier precedes a clause, it should describe a background circumstance, or an already-ongoing action or state, with obvious relevance to whatever is described in the main clause. (For an example of a background circumstance, please see the example above. Example of of an already-ongoing action: Coming home from school, the wind blew me off my bike.)

Neither of these requirements is satisfied here.

My doubt is that Unlike should be followed by Noun or Pronoun. As per Answer E, it is followed by a clause. How is it possible. Please help.

Hi sourabhgx,

The automobile company's research on crashes involving sport utility vehicles is a noun phrase. Because there's no verb in this phrase (involving isn't a (complete) verb), we're not looking at a clause. More generally, an -ing on its own, without a helping verb, can never be a complete verb.

As AjiteshArun mentions, "unlike" is not followed by a clause in E.

You can watch our video on Clauses here.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses Clauses & Phrases, their application and examples in significant detail. If you or someone is interested, PM me your email-id; I can mail the corresponding section.

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.

(D) company's research, having been based on

Can you please help me understand why D is incorrect meaning-wise?

I think the comparison is different between D & E but I am not able understand exactly how?

The research by IC took into account certain factors whereas the research by AC is based on SV crashes. So both took different factors into consideration and this difference is highlighted using "Unlike"

So how E is different from D?

Is there a difference between "Research on" vs "Research based on"?

'having been' is a perfect participle which is used to signal an event prior to another event and often tells us why the second event took place.

Having been to the play already, I did not want to go again.

There is no such meaning here and hence, (E) is better than (D).
