Sentence Correction

Does not only has to be followed by "but also" always ?

I have seen in many standard newspapers such as NY times, wall street in whihc it is not used the way we learn for GMAT .

David Cameron is trying to prove Lear wrong. He wants to demonstrate to the British electorate and the wider world that a smaller, less expensive state could not only be a better and more efficient state. It would also create more room for personal freedom and individual initiative .

Could any exeprt explain whether in GMAT, we should consider options not following not only .. but also in the intended way.

Thanks.

GMAT english and regular english have lot of differences.

This vis too much of generalisation. GMAT follows standard english generally but too rigidly. Any expert comment please.

If not only is there it must be followed by "but"' or but also, but not vice versa.

Not only...but is correct
Not only.. but also is correct
.................but also is correct (you dont need not only)

Correct me if I am wrong, i learnt these from Ron Posts and GMATFIX.
