Unlike the automobile company, whose research was based on crashes

Unlike X, Y --> Here X and Y must be ||.

Y : Research , so X must be research only. Hence, option A, B and C out.

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'a age, sex, and previous driving record.

(A) company, whose research was based on
(B) company, which researched

Dear Friends,

Here is a detailed explanation to this question-

Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of the sentence is that the automobile company's research on crashes involving sport utility vehicles is unlike the research on crashes involving sport utility conducted by the insurance company in that the insurance company's research took into account such factors as a driver's age, sex, and previous driving record.

Concepts tested here: Meaning + Comparisons

• Comparisons must always be made between similar things.

A: This answer choice incorrectly compares "the automobile company" to "the research conducted by the insurance company"; remember, comparisons must always be made between similar things.

B: This answer choice incorrectly compares "the automobile company" to "the research conducted by the insurance company"; remember, comparisons must always be made between similar things.

C: This answer choice incorrectly compares "the automobile company" to "the research conducted by the insurance company"; remember, comparisons must always be made between similar things.

D: The sentence formed by this answer choice alters the meaning of the sentence through the phrase "having been based on crashes involving sport utility vehicles"; the construction of this phrase incorrectly implies that the automobile company's research on an unspecified topic is unlike the research conducted by the insurance company in that the insurance company's research took into account such factors as a driver's age, sex, and previous driving record because it was based on crashes involving sport utility; the intended meaning is that the automobile company's research on crashes involving sport utility vehicles is unlike the research on crashes involving sport utility conducted by the insurance company in that the insurance company's research took into account such factors as a driver's age, sex, and previous driving record.

E: Correct. The sentence formed by this answer choice uses the phrase "research on crashes involving sport utility vehicles", conveying the intended meaning - that the automobile company's research on crashes involving sport utility vehicles is unlike the research on crashes involving sport utility conducted by the insurance company in that the insurance company's research took into account such factors as a driver's age, sex, and previous driving record. Further, Option E correctly compares "the automobile company's research" with "the research conducted by the insurance company".

Hence, E is the best answer choice.

All the best!

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'a age, sex, and previous driving record.

(A) company, whose research was based on
(B) company, which researched
(C) company, in its research of
(D) company's research, having been based on
(E) company's research on

My 2 cents.
It is important to identify what this q is testing.

This q is testing comparison - whether we are comparing things correctly.
If you look at the not underlined part, you can see that subject after comma is research.
So, the underlined part's subject should be research.
Then you are left with D and E.
D is wrong as the verb's form is wrong.
E is correct.

Isn't E completely changing the meaning of the sentence?

A / D) -> research based on crashes w/ spot vehicles (meaning the result was based on the subset of observations within those crashes)

E) -> research on crashes (meaning the crashes, not any other results were the focus of the sentence)

Clearly D is awkward, but shouldn't such a drastic change in meaning render option E) wrong?

^ Same as above. I'm not sure why option E is correct, since I think "research based on xx" and "research on xx" have 2 different meanings.

"Research on xx" means you're researching xx subject, whereas research based on xx might mean you're researching on other topic, but using evidences from xx subject

^^^^
I agree with Vezax27 and gmatwarrior9117.

After seeing that A, B and C were comparing the wrong things, I had choice D and E left.
I just automatically saw "research on" and eliminated E, because I was taught that on the GMAT, the word "research" followed by a preposition is always incorrect. The second portion of choice D "having been based on" sounds awkward, but because it there was no preposition after "research" I ended up picking D.

Maybe I'm not understanding the use of "research" + preposition?

If anybody can shed some light on the usage of |research" + preposition, that would be great!

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

What is wrong with the bold part except for awkwardness can anybody shed some light on this?

Hi Prashant10692 ,

There is a very good explanation given here.

Please let us know in case of any further queries.

Hello gmatwarrior9117,

I am not sure if you still have this doubt. Here is the explanation nonetheless.


This official sentence presents incorrect contrast between the automobile company and the research.

In order to maintain this incorrect contrast but to convey the intended meaning, the sentence uses the expression whose research was based on crashes.

The expression actually means that the topic of the research was certain types of crashes. The expression does not mean that the company was doing some other research and used the results of these types crashes for its research.

So there is no meaning change in the correct answer choice E. Because the correct answer presents correct contrast, the structure becomes precise.



Hope this helps.
Thanks.

Hello Everyone!

It looks like there have been some great discussions on this question already! Let's break things down even further to determine which option is the best one. Before we get started, here is the original question with the most important differences between each option highlighted in orange:

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.

(A) company, whose research was based on
(B) company, which researched
(C) company, in its research of
(D) company's research, having been based on
(E) company's research on

After a quick glance over the question and 5 options, it's clear that this is an example of a COMPARISON sentence. Whenever we see comparison questions on the GMAT, the first thing we should look at is parallelism!

This sentence uses the structure "Unlike X, Y..." to indicate this is a comparison. Both X and Y need to be parallel for this to be correct. Let's look at each sentence with the option added in to see how each answer stacks up:

(A) 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.

This is NOT PARALLEL because it's trying to compare the automobile company to research, which are not parallel in nature.

(B) Unlike the automobile company, which researched 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.

This is NOT PARALLEL for the same reason as option A: it's attempting to compare a company to research, which are two completely different things.

(C) Unlike the automobile company, in its research of 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.

Again, this is NOT PARALLEL because it's trying to compare a company to research, which aren't parallel in kind.

(D) Unlike the automobile company's research, having been 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.

This is PARALLEL because it is comparing two things of the same type: the automobile company's research and the insurance company's research!

(E) Unlike the automobile company's research 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.

This is PARALLEL because it is comparing two things of the same type: the automobile company's research and the insurance company's research!

We can eliminate options A, B, and C because they don't use parallel structure to create a proper comparison!

Now that we're left with only options D & E, let's take a closer look to find which one is the better option:

(D) Unlike the automobile company's research, having been 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.

This option is INCORRECT because it's overly wordy and slightly misleading. There is no reason to say "having been based on" when simply saying "on" means the same thing. It also subtly suggests that we should be comparing what both sets of research are based on, rather than just saying that both studies are about sport utility vehicle crashes that cover different topics.

(E) Unlike the automobile company's research 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.

This option is CORRECT because it's clear and concise! It's clear that both studies are about sport utility vehicle crashes, but that they each cover different factors. It's also much easier to say "on" rather than "having been based on."

There you go - option E is the correct answer because it's clear, concise, and uses parallel structure to show a comparison!


Don't study for the GMAT. Train for it.

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.

(A) company, whose research was based on
(B) company, which researched
(C) company, in its research of
(D) company's research, having been based on
(E) company's research on

By looking at the question we can see two things clearly : research of/on: Correct is you do research on something.
So: C out.
D. having been not acceptable in GMAT.
A. not parallel, same for B.

AjiteshArun
in option c
in it's research modifying the automobile company or the main clause ‘the research conducted by the insurance company took…’,

Hi saby1410,

You're right. That modifier is ambiguous, as we can't be sure what in its research of points to. It could refer either to the automobile company or to the research conducted by the insurance company.

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'a age, sex, and previous driving record.

(A) company, whose research was based on
(B) company, which researched
(C) company, in its research of
(D) company's research, having been based on
(E) company's research on

My 2 cents.
It is important to identify what this q is testing.

This q is testing comparison - whether we are comparing things correctly.
If you look at the not underlined part, you can see that subject after comma is research.
So, the underlined part's subject should be research.
Then you are left with D and E.
D is wrong as the verb's form is wrong.
E is correct.

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.


Unlike (used for noun) the automobile company,
- whose (modifying co.) research was based on crashes involving sport utility vehicles,
the research (sub) conducted (ed-mod.) by the insurance company took (verb) into account such factors as a driver's age, sex, and previous driving record.

error - AC is compared to research

(B) company, which researched
which also modifies company. same as A

(C) company, in its research of
incorrect comparison

(D) company's research, having been based on
having been implies sequence. eg - having been scolded, I decided to leave.

(E) company's research on
correct- research to research
