A was greatest in the North, as was B. Both A and B were greatest in the North. Just as A was greatest in the North, B was also greatest in the North.

Why not ALSO here?

 

[Raymott]

Why not ALSO here?

Why not ALSO where? Did you read this bit: "B was also greatest in the North."

Why not ALSO here?

Are you asking if choice 3 is correct?

 

[Freeguy]

Yes

It isn't. 'Also' does not function as a conjunction.
