The most vexing problem faced by researchers exploring wind-powered generation of electricity is achieving a constant flow of power from an unpredictable natural source that meets demand, but so the flow does not overload electrical grids with sudden voltage increases

A. achieving a constant flow of power from an unpred-ictable natural source that meets demand, but so the flow does not overload
B. achieving a constant flow of power from an unpredictable natural source, which meets demand but without overloading.
C. how to achieve a constant flow of power from an unpredictable natural source, a flow that meets demand but does not overload.
D. how to achieve a constant flow of power from an unpredictable natural source, but a flow that meets demand without overloading
E. how a constant flow of power from an unpredictable natural source can be achieved, which meets demand but does not overload.

The most vexing problem is "NOUN" the parallelism is maintained only when before and after part of "is" in same

but in option C "how to achieve a constant flow" is a phrase

Can some one explain

Hi RaviChandra

The basic structure of a sentence is: Subject + Verb + Object (S-V-O)
We do not have any rule that requires S and O must be parallel. S and V, however, must follow the subject-verb agreement rules.

For example:
My weakness is that I don't know how to spend on my salary

Subject: my weakness is a noun
Object: "that I don't know how to spend on my salary" is even a clause.

Hope it helps.

Hi Thankyou for the explanations. I was referring to "Watch out for Link verbs" Section in Chapter 4 "Parallelism Strategy" (MGMAT)

This part says,

Wrong: The bouquet of flowers WAS a giving of love.

The two sides of the linking verb was are the bouquet and a giving. These two sides are not as structurally
parallel as possible. In order to achieve true parallelism, we can rewrite the sentence replacing giving
with the noun gift, so that the two sides of the linking verb are as structurally similar as possible.

Right: The bouquet of flowers WAS a gift of love.

Can you please tell if i have inferred this wrong.... i bit a confused

Hi RaviChandra

I gotcha :)

You misunderstood what MGMAT wants to convey. The book means subject and object should be parallel in terms of meaning.

For example: The bouquet of flowers WAS a giving of love.
The bouquet is something real, physical. It can't be an action "giving" (gerund form of verb give) ==> You must change a giving to a gift.

That's the idea the book wants to tell you.

Please see the sentence right below the example you quoted in page 60 ==> see the underlined part "in meaning".

Hope it's clear now.
