Bad source?

"Not only..." should be followed by "but also..."

Personally I think it's ok with "not only... but" (without "also"). I myself met this type of structure several times.

The OA should be B, because skills in measuring, not "skills to measuring"

Not necessary, you can have 'not only X but Y' or 'not only X but also Y'. Both are correct.

As far as I know 'Skill in' is correct. I am trying to find out the same on net but not getting it.

IMO E.
What is the OA?

If you guys can cite an OG example of such structure without "but also..." I would like to see it.

On the other hand, I see 6 questions from the OG that have such structure, and none of the correct answer without:

Verbal Guide 1, #52.
Verbal Guide 2, #106.
Verbal Guide 2, #63.
Verbal Guide 2, #68.
Verbal Guide 2, #46.
Official Guide 11, #64.

Hi Uwhusky,
I cant tell you which qn it is exactly. But, there is only 1 GMATPREP problem that used this Not only X but Y rule.

Are you referring to this question: https://www.manhattangmat.com/forums/not ... t3129.html?

Yes.. I think this is the same one..

Read through the post, it does not violate the idiom "not only...but also..." It's an entirely different construction.

Ya... that question follows a different rule...

You may note the following:

Not only x... but also y.
&
not only x... but y - both are correct.....

In the following q but also at is not present in the non underlined part... hence you should just concentrate on not only x... but y

The skill and the precision of the Anasazi, ancient inhabitants of the Southwest, in measuring the movements of the Sun a ... t only at Chaco Canyon but at a number of other sites

(A) in measuring the movements of the Sun and Moon is evidenced not only at - is evidenced is wrong... we are measuring 2 things..
(B) in measuring the movements of the Sun and Moon are evidenced not only at - correct
(C) in measuring the movements of the Sun and Moon is evidenced at not only - lacks parallelism
(D) to measure the movements of the Sun and Moon is evidenced at not only - lacks parallelism
(E) to measure the movements of the Sun and Moon are evidenced not only at - to measure is wrong

Hope it helps... I'm searching for that not only x... but y construction for you... will post it for sure if im able to locate it...
