SC from OG again

[ayushbiy]

[OG question deleted by moderator]

- I didnt understand why C is wrong. D takes a new meaning military action rather than militarily. How can somebody know whether we were supposed to change the form altogether or not.

[divudu.v]

A and B met to consider X and Y.
Here X and Y should be parallel.

X - Russian attempt, which is a noun .
So, Y is also expected to be a noun.

Only D has Y - military action (noun)

Instructors,
Please correct me if I am wrong
