New fall shows added to the television network’s upcoming we

New fall shows added to the television network’s upcoming weeknight schedule have increased overall viewership, critical acclaim, popularity among all age groups, and have decreased ratings on the network’s shows online

A) [and] popularity among all age groups, and have decreased – require “and” before final element that was increased

B) [and] popularity among all age groups, and decreased – require “and” before final element that was increased

C) and popularity among all age groups, while decreasing [not sure about this, but doesn't seem wrong either] [Correct]

D) [and] increased popularity among all age groups, but decreased – require “and” before final element that was increased. second "increase" is redundant

E) and popularity among all age groups were increased, while decreasing – second "increase" is redundant

Two parallel elements are mentioned in the sentence-
1) 'have increased viewership' and ' have decreased ratings'
2) viewership, critical acclaim and popularity among all age groups

popularity among all age groups, and have decreased and is missing to have 2nd parallel elements
popularity among all age groups, and decreased and is missing to have 2nd parallel elements
and popularity among all age groups, while decreasing correct choice.
increased popularity among all age groups, but decreased 'increased' is not required
and popularity among all age groups were increased, while decreasing 'increased' is not required

first of all u need "and" before the last item of the identical list to make the parallelism complete---> have increased overall viewership, critical acclaim and popularity among all age groups !!
always remember that parallelism is not random ,that means that u put things in parallel only when they are suppose to be in parallel !!
so by that rule we can virtually rule out A, B and D
E is wrong again for wrong parallelism .
so C is definitely the answer here

Parallelism is the key.three items should be in parallel:: overall viewership, critical acclaim, popularity among all age groups.
There should be a and before last item.

Why not parallel structure between (A):

New fall shows added to the television network’s upcoming weeknight schedule have increased overall viewership, critical acclaim, popularity among all age groups, and have decreased ratings on the network’s shows online.

McQueen, the simple answer is that "while" is not a parallel marker. It indicates a modifier that builds on the earlier action. The fall shows have increased 3 things, and they have done all this while decreasing something else. Using a parallel verb linked with "and" or "but" would work as well, but there's nothing wrong with the modifier form in C. (I'm assuming you meant C, not D.)

Below response from Manhattan instructor DmitryFarber may clarify your doubt.

Thanks!

I think there is a typo in the question. Should it be 'ratings OF the network’s shows online', instead of 'ratings on the network’s shows online'? (The official question says 'ON').

I picked D. I was of the opinion that 'increased' in the question is parallel to 'decreased' and should not be changed to 'decreasing'. Please let me know if I was wrong in thinking so. Thank you

New fall shows
Have increased A, B, and C
And Have decreased D

A) popularity among all age groups, and have decreased - And is missing before third item in sub-list.
B) popularity among all age groups, and decreased -Same as A
C) and popularity among all age groups, while decreasing - Correct.
D) increased popularity among all age groups, but decreased - Shows have increased ''Increased popularity''...seems wrong and redundant. And is required to separate items.
E) and popularity among all age groups were increased, while decreasing - Noun are made parallel with clause. Wrong.

Kudos please....

Here in the above question, parallelism is at issue.
Viewership, acclaim, and popularity have to parallel and without any conjunction before the third itme parallelism cannot be established.
C offers us the same
Hence C is correct

OFFICIAL EXPLANATION

The correct response is (C). Adding new fall shows have increased overall viewership, acclaim, and popularity. However, they have also decreased online viewership for that network . For sentence clarity, the list of three elements that have been increased require “and” before the final element. Also, contrast is needed between these three positive effects and the one negative outcome for the overall meaning of the sentence to make sense.

Hi,

I am confused about this question,
I was expecting to see an option which has " have increased - while ....have decreased"
So isn't there any problems with the usage "have increased- while decreasing" in the OA, don't these need to be parallel?

I will appreciate any clarification.

In strict sense "while" is a conjunction and hence a subject and verb should follow. But here "while"+ "participle" is also acceptable. Here it acts as an adverbial modifier and gives us additional information about another effect.

New fall shows have A, B and C and have X.---Parallelism is correct.
New fall shows have A, B and C (while) decreasing X---How is this parallel?
