1st point of elimination : IDIOM is  greater..than  and  more..than  NOT  greater..as  or  more...as

OPTIONS LEFT : C and E

E has verb error : for plural differences singular 'is' is being used. HENCE answer is c

gamelord · Answer

I'd like to know "greater ... than" should be used only refer to single statistic otherwise used "more ... than".
Why greater ... than could be used here ?

varunjoshi31 · Answer

My approach to solve this as follows :

1. Here sense of smell is being needs to be parallel with the underline statement "scenting ability"
2. Since sense of smell is singular we need is ... Eliminate D & E
3. In A,B and C B has an error with inappropriate use of more, hence eliminated
4. Between A and C, C has the correct usage of the idiom

VKat · Answer

In option a, if we would have "more than " in place of "more as", so that time, can we go with option a

sayantanc2k · Answer

Yes, A would then be correct. Moreover, you may as well omit the repeated part "there is", bringing you to the OA C.

(I did not understand what you meant by the phrase "so that time".)

thangvietname · Answer

in choice E. "differences between two members" is not logic. there is only one difference. there can not be many differences between two members , at least in this context of this sentence.

Skywalker18 · Answer

Though certain breeds of dog are renowned for their sense of smell, there  is often a greater difference in scenting ability between two members of a single breed as there is  between members of different breeds.

A. is often a greater difference in scenting ability between two members of a single breed as there is -- idiom issue -- greater ... than
B. is often more difference in scenting ability between two members of a single breed as to find one - idiom issue -- more .. than
C. is often a greater difference in scenting ability between two members of a single breed than - Correct
D. are often greater differences in scenting ability between two members of a single breed as there are -- idiom issue - same as A ; also differences is incorrect as we are talking about only kind of difference
E. are often greater differences in scenting ability between two members of a single breed than there is - two verbs in this choice are not in the same quantity

Answer C

GMATPolvon · Answer

Could the 'as' in answer A mean the resemblance?, and why it is not a correct answer?

pyaasa · Answer

Why is ‘in scenting ability’ not repeated in C?

Greater x in ability than y!

Hi pyaasa Let's look option C. Though certain breeds of dog are renowned for their sense of smell, there is often a greater difference in scenting ability between two members of a single breed than between members of different breeds. here we are comparing difference in scenting ability between 1.two members of a single breed and 2.members of different breeds. Thus comparison is fine if we don't use scenting ability with both nouns. As long as sentence makes sense we can omit scenting ability here. Hope this helps

CrackverbalGMAT · Answer

Hi

It is not clear what you mean by "resemblance". Resemblance between what? Please clarify.

The sentence is clearly comparing the "differences in scenting ability" between:

a) two individuals of the same breed
b) members of different breeds

When comparative forms are used, we need to make use of "than" and not "as", which is typically used to denote same-ness. Hence, the usage of "as there is..." in option (A) is incorrect.

Hope this clarifies.

Though certain breeds of dog are renowned for their sense of smell, there  is often a greater difference in scenting ability between two members of a single breed as there is  between members of different breeds.

Meaning analysis:   Some breeds of dogs are well known for their sense of smell. But, there is a big difference in the scenting ability between two members in the same breed compared to between two members of different breeds.

So if X and Y are two different breeds and if A and B belong to breed X then... there is a big difference in the scenting ability between A and B as compared to between X and Y.

Sentence Structure:  
Though  (contextual word that means there is some change/difference in the direction the information is going to be presented) 
certain breeds  (subject) 
of dog  (prepositional phrase that modifies "breed") 
are renowned  (verb) 
there is  (verb) 
for their sense of smell  (prepositional phrase that gives additional information stating "for what" the dogs are renowned) 
often a greater difference ("greater" is the comparison word)
in scenting ability  (this is the property on which the comparison is being made) 
between two members of a single breed (element 1 of comparison)
as there is  ("as" is used to mark the end of the comparison marker)   (the correct comparison marker is "greater than") 
between members of different breeds.  (element 2 of comparison)

As mentioned in the Sentence structure, the correct comparison marker is "greater than" and not "greater as"

Again, the correct comparison marker is "more than" and not "more as". Moreover, the phrase "to find one" makes the sentence inferior. "between two members of a single breed" cannot be parallel to "to find one"

Correct. All entities are made parallel. The correct comparison marker "more... than" rectifiers the comparison error.

Same error as (A). Note, "there are greater differences..." is parallel to "there are between...". I believe the parallelism out here is correct.

Here the singular verb "is" is used for plural entity "differences".

Correct Choice:  (C)

CEdward · Answer

There are a number of ailments that the incorrect choices are suffering from in this example. The first thing to note is that 'greater...than' is idiomatic not 'greater...as' in comparison-based questions

(A) is often a greater difference in scenting ability between two members of a single breed  as  there is
(B) is often  more  difference in scenting ability between two members of a single breed as  to find one 
(C) is often a greater difference in scenting ability between two members of a single breed than (Correct)
(D)  are  often greater  differences  in scenting ability between two members of a single breed  as there are 
(E)  are  often greater  differences  in scenting ability between two members of a single breed than there  is

In D and E, the use of the plural 'are' and 'differences' does not make sense. If interpreted literally, that would mean there are multiple differences in scenting ability between two members of a single breed.

In choice E, if "there are" replaces "there is", is E correct?
