Electronic Mail Systems

[sk8ternite]

Because a large number of electronic mail systems exists having hundreds of thousands of subscribers, prove that while Americans may write fewer letters, another method of communication has arisen to take the place of writing letters.

(a)Because a large number of electronic mail systems exists having hundreds of thousands of subscribers, prove
(b)That there exists a large number of electronic mail systems that have hundreds of thousands of subscribers is proof
(c) The existence of a large number of electronic mail systems, which have hundreds of thousands of subscribers, proves
(d) Electronic mail systems, which have hundreds of thousands of subscribers, by their existence prove
(e) The existence of electronic mail systems having hundreds of thousands of subscribers are proof

Whats wrong with B? I thought C was wrong because we do not know what which is modifying, electronic mail systems or a large number of electronic mail systems. What is the rule with which?

IMO - C

The existence....., which...proves
I am not sure why exactly B is wrong but one reason can be

That there exists a large number of electronic mail systems that have hundreds of thousands of subscribers is a proof - without 'a' sounds the sentence sounds awkward.

That is just my opinion there may be much better reasons to eliminate 'B'. On the whole option B sounds awkward.

[vikram_k51]

C seems the best.

In my opinion one reason why B could be wrong because
there seems to be ambiguity as to what is the proof "existence of electronic mail systems " or "having hundreds of thousands of subscribers "

while in C, there is a non essential clause starting with ",which" and it clarifies that the clause "The existence of a large number of electronic mail systems" is the proof.

I hope i am clear

C SEEMS BEST

EXPERTS PLEASE HELP!

I agree with "mehravikas" explanation. Also, we need to have "a" before proof.
