To find out the land area of each of the countries you:
141,973 - 673= 141,300
141,300 / 2 = 70,650
A= 70650 + 673 = 71,323
B= 70650
To check these answers you can add them both together and they add up to 141,973
I believe a "a bird" is a subject because I did process of elimination. It can't be a verb, because you cannot "do a bird." It depends what the context of the sentence is as well. Is there a clear object, or subject? Otherwise, I would say subject.
