The correct verb is "represent" leaving us with B, C and E. B's "one of which is" distorts the meaning. C's "each of which of those borrowed" makes that phrase a subject, requiring it's own verb and "represent" is already for "All the letters...".

This leaves us with E.

Why is "one of which" wrong? I felt E is distorting the meaning. In such sentences, how do we determine which is the intended meaning? I usually take what A conveys as the original meaning. here this is clearly not working.

You're right that choice A conveys the intended meaning of the sentence and that the correct choice must echo the meaning that A conveys. But according to MGMAT, one can veer off from A's intended meaning if the meaning is non-sensical.

At this point, it's a matter of debate. I just feel that "one of which is borrowed from either Latin or Greek" isn't right. To say out of all of the letters in the Cyrillic alphabet, and say that one of those letters came from either Latin or Greek - I just feel that it should be changed. Sorry I couldn't be more technical.

In my review, I often see that the GMAT's intended meaning can be debated, especially when you're choosing between two "grammatically correct choices". The answer can very well be B since it's grammatically correct.

Maybe others could chime in.

Can somebody expalin me what is difference in usage of the words "represent" and "represents"???

I too agree that the orginal sentence should be changed to get a full meaning..

first by saying all of the alphabhets and then by saying one of which doesnt make any sense.
the second sentence shud be each of which -> which refers to all of the alphabets..
Agree with the answer E.
@Utin,
Represent is used as a verb when referring to plural subjects.
Represents is used as a verb when referggin to singular subjects.

since All of the alphanbets is the suject here, it is a plural one and it needs a plural verb represent and not represents.
Hope this answers your question.

I felt the same way as you did..........My option is E

All represent ............represent for plural noun.........

He represents ...........represents for Singular noun

Has to be E.
Represent should be the correct usage becasue of 'letters' being plural!

After using All, each of which makes sense

IMO E.

We need "represent" and "each of which"

Whenever in doubt whether to use represent or represents.. go by this rule:

Say in your mind "Boys play; Boys play"... You will never go wrong..
You cant use Boys plays.. or Boy play.. you will use the right S-V everytime..

+1 E
"All of the letters" is plural, so A and D out. (representS)
B changes the meaning. The sentence is talking about the letters, not about an specific letter.
C is ackward ("of those"?)
E is right. Each is singular (IS).

I think I deserve kudos

In case of SANAM Pronouns like ALL ( in this case ), we look for object of " Of " i.e. Letters here that is Plural.
or u can remember this as SANAM of IT then verb should be singular
SANAM of THEM ( e.g. letters here ) then the verb should be Plural : Represent : so left with B,C or E.
C goes out because of Highlighted Text
B goes out as One of which does not convey the message for including every Cyrillic Alphabet but E does
E : Correct Ans.

why E , "each of which" is singular so it should be "Represents"
So Option D is better , it eliminates this error.

each of which is the correct usage.
represent plural form is required here.

E fits the bill.

All of the letters in the Cyrillic alphabet, one of which is borrowed from either the Greek or Latin alphabet, represents specific sounds in spoken Russian.

one of which is borrowed from either the Greek or Latin alphabet, represents
one of which is borrowed from either the Greek or Latin alphabet, represent
each of which of those borrowed from either the Greek or Latin alphabets, represent
each of which has been borrowed from either the Greek or Latin alphabet, represents
each of which is borrowed from either the Greek or Latin alphabet, represent

All...represent, 'each' should be there, also E is more concise and non-wordy.

I have a question around C. If we remove [of those] from C, will C be grammatically correct?
In other words, will the usage of [either the Greek or Latin alphabets] will still be valid or invalid in the current context of the sentence? If different, how will it mean different?

Just for additional reference, new C will look like:
All of the letters in the Cyrillic alphabet, each of which of those borrowed from either the Greek or Latin alphabets, represent specific sounds in spoken Russian.

All of the letters in the Cyrillic alphabet, one of which is borrowed from either the Greek or Latin alphabet, represents specific sounds in spoken Russian.

(A) one of which is borrowed from either the Greek or Latin alphabet, represents

(B) one of which is borrowed from either the Greek or Latin alphabet, represent

(C) each of which of those borrowed from either the Greek or Latin alphabets, represent

(D) each of which has been borrowed from either the Greek or Latin alphabet, represents

(E) each of which is borrowed from either the Greek or Latin alphabet, represent


Good one
