A new telecommunication device gives the user the freedom to choose no

Bunuel,

I think C can't be the answer to this-if you look at it, it is not parallel. It should have 'gives the freedom to choose not only A but also B(A and B both should be nouns). But this is not the case here.

A. gives the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission are used to send

B. is giving the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission are used for sending

C. gives the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission is used to send

D. is giving the user the freedom to not only choose the radius of the distance of the signal, but also which of two differently priced methods of transmission is used to send

E. gives the user the freedom to choose not only the radius of the distance of the signal, but also to determine which one of two differently priced methods of transmission is used for sending


I am finding it difficult to find the right answer. Answer choice C is using non parallel structure not only + noun phrase , but also + relative pronoun phrase

What is the subject of the second clause?

"Methods" or Transmission or Methods of transmission"

Need some expert view.

Which is a pronoun. It can easily substitute nouns. I see no problems here. C is correct.

Logically going by the options available to choose the answer from, option C suits the requirements. Explained below

A. gives the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission are used to send- which of two differently priced methods of transmission are used. This statement has verb error "are" cant be used with singular subject- which of two .
B. is giving the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission are used for sending- "is giving"(present continuous) is wrong as the statement simply presents a fact and therefore the use of Simple Present tense is imperative

C. gives the user the freedom to choose not only the radius of the distance of the signal, but also which of two differently priced methods of transmission is used to send- Bingo! This is presented in Simple present tense and also uses "is" for subject "which of two".

D. is giving the user the freedom to not only choose the radius of the distance of the signal, but also which of two differently priced methods of transmission is used to send- "is giving"(present continuous) is wrong as the statement simply presents a fact and therefore the use of Simple Present tense is imperative. Also, use of "to not only choose" changes the intended meaning of the sentence

E. gives the user the freedom to choose not only the radius of the distance of the signal, but also to determine which one of two differently priced methods of transmission is used for sending- "for sending" is wrongly used. In depth detail discussion for why it is wrong is presented here: https://gmatclub.com/forum/to-verb-vs-f ... 44017.html

VERITAS PREP OFFICIAL SOLUTION:

Of the several decision points available to you on this problem, two should stand out as absolute, binary choices:

-Parallel structure in a not only...but also construction

-Subject-verb agreement

Remember: arguably your greatest weapon on Sentence Correction is that you control the order in which you make decisions, so you do not necessarily have to deal with the first decision ("gives" vs. "is giving" ) first. If you are unsure of the absolute nature of any decision ("is giving" is strange because it's a temporary action, as though right now at this ver moment a user is being given these choices...but is it 100% wrong/illogical?), you always have the power to search for a decision you prefer.

The "not only...but also" distinction is a great one because wrong answers are easy to eliminate. If you ignore everything from "not only" through "but also," what's left needs to make complete sense as its own sentence, and here two answers do not pass that test:

(A) ...gives the user the freedom to chose which of two methods (this works)

(B) ...is giving the user the freedom to choose which of two methods (this also works)

(C) gives the user the freedom to choose which of two methods (this also works)

(D) is giving the user the freedom to which of two methods (this doesn't make sense)

(E) gives the user the freedom to choose to determine (this doesn't make sense)

So now you're down to (A), (B), and (C), and here you may see a subject-verb agreement decision toward the end of each choice between "is used" and "are used." What is the subject? Note here that "two differently priced methods" is part of a modifier:

A new device gives he user the freedom to choose...which of two differently priced methods...

So "which" is the singular subject (and if you think logically, too, the user chooses one of the two, so only one method is actually used to send the signal). This means that you need the singular "is," and only answer choice (C) properly uses both the proper singular verb and proper "not only...but also" parallelism, so (C) is correct.
