Hi e-gmat,

My analysis on this question. Could you please review and let me know if my thought process is correct -

Marconi's conception of the radio was as a substitute for the telephone, a tool for private conversation:instead, it is precisely the opposite, a tool for communicating with a large, public audience.

Hi Nishant,
Thank you for posting your query here and a very good analysis I must say!

SENTENCE STRUCTURE

Marconi's conception of the radio was as a substitute for the telephone, a tool for private conversation:
• instead, it is precisely the opposite, a tool for communicating with a large, public audience.

OPTION A: Incorrect

1) The way this sentence is worded, it suggests that Marconi’s conception was a substitute for the telephone. This meaning is absolutely illogical because an idea cannot be a substitute for a tool. From the context, we can understand that the radio was conceived as a substitute for the telephone. Hence, this sentence has meaning error.
2) The pronoun “it” seems to illogically refer to “Marconi’s conception”.

The Noun + Noun modifier “a tool for private conversation” modifies “telephone” correctly, since logically we know that radio is not a tool for private conversation.

OPTION B: Incorrect

1) “but” acts as a parallel market in this choice and is followed by a “which” clause. However, this “which” clause is not parallel to anything that lies on the left side of the marker.
2) Also, it is not clear what the modifier “which” refers to in this sentence. It can either refer to “radio” or to “telephone”.

As you have mentioned, “but” should be followed by an independent clause. However, the clause starting with “which” is not an independent clause.

OPTION C: Correct

This option changes the subject from “Marconi’s conception” to “Marconi”. This removes the meaning error of the original sentence.
Also, “it” in the second clause clearly refers to radio.

Here, “that” doesn’t refer to radio. It refers to “a tool for private conversation”.

OPTION D: Incorrect

1) “Conceived of X to be Y” is incorrect idiomatic usage. The correct usage is “conceived of X as Y”.
2) The relative pronoun modifier “which” seems to modify “telephone”. This gives an illogical meaning.
Note that, “which” can’t jump over “to be a tool for private conversation, a substitute for the telephone” and modify “radio” since this modifier is not one unified phrase.

OPTION E: Incorrect

1) This choice repeats the idiom error of option D.
2) The phrase “other than what” is wordy and redundant. It gives the meaning similar to “precisely the opposite”.

Hope this helps!
Deepak

The question is basically testing Idiom and Pronoun usage.

A: Conception X was as Y
B: Conceived X as Y
C: Conceived X as Y
D: Conceived X to be Y
E: Conceived X to be Y

Logic: Correct Idiom: Conceived X as Y. So A, D and E are eliminated

B: "which" : goes back to 'conversation' rather than back to 'radio'.

E: Correct. Correct Idiom, Present Perfect tense and no ambiguity.

Hope it helps!

Can someone please explain the error in option B. I read MGMAT and BTG explanation regarding the same but its still not clear to me.

Marconi’s conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is precisely the opposite, a tool for communicating with a large, public audience.
B. Marconi conceived of the radio as a substitute for the telephone, a tool for private conversation, but which is

As per Mitch:
Quote:
http://www.beatthegmat.com/og-12th-ed-marconi-conception-t62687.html#280168
In B, the pronoun which seems to refer -- incorrectly -- to the telephone, but the radio is the tool for communicating with a large, public audience.
>> Request someone to explain it further with example.

As per Ron
Quote:
http://www.manhattanprep.com/gmat/forums/post36053.html#p36053
that choice says "BUT which..."
this means that "which..." is the second part of a parallel structure. the first part of this parallel structure is "a tool for private conversation".
BOTH parts of this parallel structure modify "telephone". (this is how parallel structures work: both/all parts of them MUST have the same grammatical function.)

After cutting the fluff:
as a substitute for the telephone
but which
is precisely the opposite, a tool for communicating with a large, public audience.

Does this mean
X conceived of Y as Z but <..>
What follows but shall be || to Z.

Option C : Correct:
Marconi conceived of the radio as a tool for private conversation that could substitute for the telephone;
instead, it has become precisely the opposite, a tool for communicating with a large, public audience.

Hi JarvisR, B mentions: ....but which is...

Whenever we have this kind of structure (but which, and that, but that etc.), there has to be a corresponding parallel structure to the left of the conjunction (and/but).

In B, there is no corresponding parallel structure on the left hand side of but. Hence, B is not correct.

I appreciate your inputs on the shared query.

This seems to be in line with Ron's explanation. Can u please confirm, if i understood it correctly (i have mentioned the structure breakdown in my original post).

Also, some of the posts point that "which" links to telephone. To me its ambiguous, can be telephone/radio.

Hi JarvisR, you mention:

What follows but shall be || to Z.

As I mentioned in my above post, what follows but is: which is..., and so, there has to be a corresponding which structure on the Left hand side of but.

Currently, there is no "which" structure on the Left hand side of but. In other words, what follows but is actually not parallel to anything; in fact, that is the problem with B.

So, it would not be appropriate to mention that what follows but is parallel to Z.

Hi JarvisR, I think we are doing a bit of circulation argumentation here. What I have been saying is that which is not really parallel to anything. So, it's a moot point discussing what "which" is referring to.

In other words, had there been a which structure on the LHS of but, then whatever the which on the LHS was referring to, which on the RHS would refer to the same entity. Since we don't have a which on the LHS, we can't figure out what "which" on the RHS is referring to.

I believe that the construction is perfectly fine:

The conception was something but it has become something else. It denotes the change that has happened.

A. Incorrect - Because in this sentence the subject is "Marconi's conception" which do not agree to the latter part that starts after "it is". Why? because, "Conception" cannot be a tool for communicating with a large, public audience.

B. Incorrect - Which is used incorrectly

C. CORRECT - The sentence says that "Marconi came up with "Radio" as a way of private communication which could substitute "Telephone"; instead, it has become opposit (past perfect for is used) because "Telephone" has already become a tool if communication with a large public.

D. Incorrect - Use of "to be" is incorrect

E. Incorrect - Use of "to be" is incorrect
