Managing your irrigation system well and watering your grass wisely not only saves water, but helps to ensure the success of your lawn.

A. saves water, but helps to ensure the success of your lawn.
B. saves water, but also help to ensure the success of your lawn
C. saves water, but the success of your lawn is more helpfully ensured
D. save water, but also help to ensure the success of your lawn
E. save water, but also the success of your lawn is more helpfully ensured

The answer here is just APPAULING!

OK, let me see if I can explain this for you. There are a few key issues at play on this question. First you have the "not only..., but also" phrasing. When you use "not only" you need "but also" to complete the phrase, so A & C are eliminated.

Second you have to determine the proper Subject/Verb agreement (the saves/save split at the beginning). Your subject is the combination of noun phrases - "Managing your irrigation system well" (one 'thing') and "watering your grass wisely" (another 'thing'). The word 'and' is very powerful and it creates a compound, or plural, subject. The plural subject requires the plural form of the verb, so we want 'save' (no 's' on the plural form of the verb) - eliminate B.

We're left with D & E, and here comes parallelism to finish it off. When we say 'not only SAVE water', we are going to need a verb (HELP) after 'but also' to maintain parallelism - eliminate E. That leaves us with answer choice D.

Does this help? Do you have other questions?

Kyle i have seen answers with not only and but. Do you think We can use this argument here ?

Great question. In the case of this sentence, answer choices A & C (missing 'also') have a grammatical error with the singular verb 'saves', so the question don't really make us choose between 'but also' or 'but'. It's probably best to say that 'not only X, but also Y' is preferred but 'not only X, but Y' is acceptable. When in doubt, look back to rock solid grammar rules like subject/verb agreement.

Great explanation. I was hoping that the question was erroneous. Reminder to brush up on basics

e) save water, but also the success of your lawn is more helpfully ensured

In tha above Doesnt the correct ans seem awkward? Somehow "saves water but helps" sounds better? Can any expert explain this ans..

SOME THEORIES:
1) If two nouns are connected by AND then the resultant subject is compounded hence plural and thats why it needs a plural verb.
2)correct idiom is NOT ONLY X,...BUT ALSO Y...==>X AND Y SHOULD BE PARALLEL.

In this question two nouns PHRASE i.e
1)irrigation system well and 2) watering your grass wisely
they are connected by AND hence needs a plural verb.

basing this we can eliminate option A/B/C ..because they contain singular verbs SAVES

now between D AND E
IN E SAVE WATER....is not parallel to the success of.....

hence correct option D

HOPE IT HELPS

This question relies on the conjunction not only ... but also. The construction is awkward but grammatically correct and is often tested because of this fact. Once you Eliminate A and C for an incorrect conjunction then you need parallelism to surround that conjunction - save and help must be in the same form - they must be either saves and helps or save and help

Is D the answer. I would choose D because managing and watering need the plural verbs. Saves and Helps are not plural verbs but singular verbs.

"not only" but "also"...... : idiomatic usage
"saves", "helps" : parallelism

Came across this question in the free GMAT verbal test.
I can't understand exactly why it should be D and not B.
I get the claims of idiom but not the ones about parallelism here...

The sentence with "save" doesn't somehow read so well for me...Can someone please explain this?

My Pick : D
Correct idiom usage,
E is awkward
You can also do a 3/2 split between saves/save and between idiom usage
not only...but/not only... but also

Managing your irrigation system well and watering your grass wisely not only saves water, but helps to ensure the success of your lawn.
1 issue with original sentence: incorrect idiom
Quote:
a. saves water, but helps to ensure the success of your lawn ---incorrect idiom
b. saves water, but also help to ensure the success of your lawn ---saves/help conflict
c. saves water, but the success of your lawn is more helpfully ensured ---incorrect idiom +weird
d. save water, but also help to ensure the success of your lawn
e. save water, but also the success of your lawn is more helpfully ensured ---correct idiom but obviously weird

Try reading the sentence this way:
Managing your irrigation system [strike]well and watering your grass wisely[/strike] not only saves water, but helps to ensure the success of your lawn.

Now read it with option D :
Managing your irrigation system [strike]well and watering your grass wisely[/strike] not only save water, but also help to ensure the success of your lawn

Now lets see with option B:
Managing your irrigation system well and watering your grass wisely not only saves water, but also help to ensure the success of your lawn
saves and help do not agree in verb (I don't know what word to use..... singular/plural clash)....I hope you are getting what I am trying to say,
it can either be saves/helps...or save/help, but any other choice option has incorrect idiom usage.
hope this helps,

PS: I have a silly one what the hell does OA stands for????
to this day I can't figure it out, I know I just did/offered OA but its annoying not to know what it stands for...aaarrrghhh!

How is this not A??? "save water". No one writes like that in English. GMAC needs to get in touch with f***ing reality. I can understand the parallelism structure is off, but that's just not grammatically correct.

Not only .... but also

Not only and but also go hand in hand in a sentence , this idiom helps in bringing || between two phrase/clause after not only and but also.

I have seen not only .. but also used without also too, still the sentence was gramatically correct.
