it is or those are?

[KLPNO]

Hello everyone,

Should I use plural or singular in the following sentence?

It is the south and the east of the country where the company wants to concentrate its activities.

Or should it be "Those are..."?

Thank you.

[5jj]

It is.

[KLPNO]

It is.

Thank you, fivejedjon.

Note such it is = plural noun who sentences as:

It was men who went to war, but it was women who urged them to go.
