I have tried and tried but have not been able to justify this answer in a way that it makes sense to me. Out of all the sentence correction practice questions I have done this has been the 1st that has set me back

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

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
