Hi abhi398.
I'm glad to help.

The simple concept of personal computing, hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society, remains perhaps the most important technological idea of the last 50 years.

a) hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society
Correct. "hatched" (Verb-ed modifier) || permeating (Verb-ing modifier) <== both modify "the simple concept of PC".
Note:
* Verb+ed modifier ==> always modifies a preceding NOUN - a concept of personal computing. The modifier does not modifies the nearest noun - personal computing because of the critical mission preposition "OF".
* Verb-ing modifier + comma ==> modifies a preceding clause. The preceding part is not a clause, but a noun phrase. ==> "permeating" modifies "the simple concept of PC".

b) which was hatched by several Silicon Valley entrepreneurs and that permeated almost all of modern society
Wrong. Parallelism problem.

c) which was hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society
Wrong. Parallelism problem.

d) hatched by several Silicon Valley entrepreneurs, and which permeates almost all of modern society
Wrong. Parallelism problem.

e) a concept hatched by several Silicon Valley entrepreneurs and that permeated almost all of modern society
Wrong. Parallelism problem.

Hope it helps.

Until now I thought that for parallelism, one side needs to be parallel with the other i.e. -ed / -ed, or -ing / -ing. Now this jumps off!
a) thanks for the explanation
b) can you pinpoint to some references? I can't find something similar in the MGMAT SC guide...

A is the only answer choice that maintains parallel structure.

"The simple concept of personal computing" is modified by:
- hatched by several Silicon Valley entrepreneurs. Verb-ED Modifier
- and permeating almost all of modern society. Verb-ING Modifier (with no comma)

Even if it sounds counterintuitive, a Verb-ED Modifier and a Verb-ING Modifier (with no comma) are parallel.

Another way to think about this is that they are both phrases that modify a noun.
You can mix phrase + phrase (answer choice A) but you cannot mix phrase + clause (answer choices C, D, and E)

The simple concept of personal computing, hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society, remains perhaps the most important technological idea of the last 50 years.


The question becomes very simple if you just rearrange the parts of the sentence as follows :

Hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society
, the simple concept of personal computing remains perhaps the most important technological idea of the last 50 years.

This makes it very clear that the modifying clause "hatched by ....& permeating almost...." is modifying the SUBJECT "The simple concept" ...

If we don't do this, the original sentence gives you an impression that "hatched" (a verb-ed modifier) is modifying the noun "personal computing" which is right before the modifier... (I made this mistake and got the question wrong)

Once you do this, the question becomes a parallelism question and you just have to check whether "hatched" and "permeating" are parallel to each other ...and yes they are ...

This structure is not present in any of the answer choices except A ..

Hence A is correct.

a) hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society
b) which was hatched by several Silicon Valley entrepreneurs and that permeated almost all of modern society
c) which was hatched by several Silicon Valley entrepreneurs and permeating almost all of modern society
d) hatched by several Silicon Valley entrepreneurs, and which permeates almost all of modern society
e) a concept hatched by several Silicon Valley entrepreneurs and that permeated almost all of modern society

Why is option E wrong
That in D refers to concept so i think it is alright and is parallel .
Am i correct in my reasoning ?
Please explain

In option E "hatched" and "that permeating" are not parallel....

Hence, E is incorrect...

Had it been "a concept THAT hatched...and THAT permeating..." than it would have been grammatically parallel ...

Does this makes sense ?
