Need to clarify this

It was the coincidence of the geographic range of the sickle cell gene and malaria that first drew attention to the possibility that the sickle cell gene might confer resistance to the disease.

Here in option A , wont that just point to malaria as that always points to the previous noun

or that will refer to the coincidence of ............. sickle cell gene and malaria -
which means that points to coincidence .....

Any help would be appreciated


No, "that" (or any modifier as such) does not necessarily refer to the previous noun (i.e. the noun touching it).

This is an emphatic usage "it was X that did Y". Here "that" refers to "coincidence".

Please note that there are exceptions to "modifier touch rule" and this is such an exception. Another mission critical modifier (especially prepositional modifier) may come in between a noun and its modifier. Here the prepositional modifier "of the geographic range of the sickle cell gene and malaria" comes in between the "coincidence" and "that" and such exceptions are allowed in GMAT.

[Nonetheless I see a different problem with option A: it appears that "that of" is missing before "malaria". Probably the parallelism is violated - " geographical range" is compared to "malaria". The correct sentence would be:

It was the coincidence of the geographic range of the sickle cell gene and that of malaria that first drew attention to the possibility that........

There should be 3 "that"s in the sentence; I have tried to match them with their respective antecedents using different colours above.]

(A) It was the coincidence of the geographic range of the sickle cell gene and malaria that
--> CORRECT

(B) It was the geographic range of the sickle cell gene coinciding with malaria that
--> seems to say range coincided with malaria-illogical
Also meaning is changed: also the coincidence should be the main subject as because it was the coincidence NOT the geographical range that drew the attention

(C) The geographic range of the sickle cell gene coinciding with malaria was what
-->seems to say range coincided with malaria-illogical

(D) The geographic ranges of the sickle cell gene and malaria coinciding was what
--> In this sentence subject is plural (geographic ranges) hence singular "was" is incorrect

(E) It was that the geographic ranges of the sickle cell gene and malaria were coincident that
--> awkward and full of problems

Hi,

Good question.

We are comparing the geographic ranges of the sickle cell & malaria & not just the geographic range of the sickle cell

Hope this clears your doubt :-)

It was the coincidence of the geographic range of the sickle cell gene and malaria that first drew attention to the possibility that the sickle cell gene might confer resistance to the disease.

(A) should be wrong coz it is comparing geographic range of the sickle cell gene with malaria
IMO it should compare the coincidence of the range of the two.

(B) B also same problem

(C) C also same problem

(D) here the word ranges says that they are comparing the two ranges...

(E) awkward.

Guys please correct me if i am wrong .
am i missing out on the meaning of the sentence

Using your interpretation, since there are multiple geographic ranges, shouldn't "geographic range" be plural?

Here the usage of "that" is as follows:

The relative pronoun "that" is used to create to a copy of the noun it refers to ("geographic range"). The usage is similar to the following:

The car I used to have was bigger than that I have now.

A present participle modifier by itself cannot be used as the subject of a sentence. In option D, "coinciding " is a present participle modifier (X and Y coninciding) and hence cannot be used as a subject.

Verb-ing used a gerund can be subject of a sentence. e.g. Singing is my favourite hobby. ....correct.
Verb-ing used as a present participle cannot be the subject. e.g. Jane singing is very nice to listen to......wrong. (This usage is similar to to option D)

I would say your interpretation and the question are more like this:

The car you have and that I do are blue. (Your interpretation)

Vs

The car you and I have is blue.

If your interpretation is correct, the question should be:

The cars you and I have are blue.

Does this make sense?

Yes, probably I understand your point. That is the reason I suggested that "that of" is required before "malaria":
....coincidence of the geographic range of the sickle cell gene and THAT OF malaria...

Instead, let us consider that the singular "geographic range" is changed to plural "geographic ranges" as follows:
....coincidence of the geographic rangeS of the sickle cell gene and malaria...

This in my view is slightly ambiguous. This usage may imply that the multiple ranges are common for both sickle cell gene and malaria. The idea that two different ranges (one of sickle cell gene and the other of malaria) coincided is not very clear. The "car" example above would probably make the problem clearer:

The cars you and I have are blue...... this may imply that you and I own the same cars, and those cars are blue.
The car I have and that you have are blue.... this makes it clear that your car and my car are not the same, and they are blue.

Did I understand your point correctly?

Exactly. If the GMAT sentence had said "that of" there would have been no ambiguity. Unfortunately, this is only hypothetical.

The reality is that the "geographic range" in the sentence represents two geographic ranges, so grammatically it should be plural. I'm sure there is a reason for the singular form to be correct, some kind of exception, but what is it? How can we generalize this reason, this rule, this exception?

In the car example, let's try to make it resemble the GMAT sentence even more:

"The car of mine and that of yours"

Now, without the option of saying "that of", which is the case in the GMAT sentence, would you say, with the objective of retaining the original meaning,:

"The car of mine and yours"?

I think saying it that way would imply there is only one car. Likewise, saying "the geographic range of the sickle cell gene and malaria" implies only one geographic range.

Or maybe there is in fact only one geographic range?

In order to have a coincidence there has to be two distinct entities, not one - one entity cannot coincide all by itself. Hence there must be two ranges (one of SCG and the other of M). Therefore in my view the usage of singular or even a plural that belongs to both the groups simultaneously is not correct - there has to be two different groups that concincide.

It was the coincidence of the geographic range of the sickle cell gene and malaria that first drew attention to the possibility that the sickle cell gene might confer resistance to the disease.

(A) It was the coincidence of the geographic range of the sickle cell gene and malaria that--------> looked pretty right Answer

(B) It was the geographic range of the sickle cell gene coinciding with malaria that ----> Incorrect.Showed Illogical relationship between geographic range and the sickle cell

(C) The geographic range of the sickle cell gene coinciding with malaria was what ------>Incorrect for the same reason as Answer Choice B and use of what is suspicious in Correct Answer Choice

(D) The geographic ranges of the sickle cell gene and malaria coinciding was what --------->Incorrect for the same reason as Answer Choice B and use of what is suspicious in Correct Answer Choice

(E) It was that the geographic ranges of the sickle cell gene and malaria were coincident that----->Incorrect for the same reason as Answer Choice B,in addition to this reason this choice is ambiguous(used "that" two times illogically)

Correct Answer A

Can you please explain this. Specially I am not able to understand the thing about why there need to be two distinct entities?

It was coincidence of time that Einstien and Max Plank both researched on Particle Physics.

This suggests that Einstien and Max Plank both researched Particle Physics at the same time.

Here also, it says It was the coincidence of the geographic range of the sickle cell gene and malaria

This suggests that sickle cell gene and malaria both had the same geographic range.

Where am I going wrong in my interpretation?

So you're basically saying the GMAT's official answer is incorrect? I would agree with that. What a weird GMAT question.
