A. It's, because the birds gender is unknown
I would say b or c. Tbh if it was me answering I would go with c. Hope this helps!!
I would say Subordination but i would get a second opinion
Major.
Because the subject of the sentence is "I", "major" is the subject compliment.
I hope I helped! :))
I actually did this for an assignment awhile back. First of all I would use “following through WITH a promise” unless the assignment said on. I can’t remember exactly what I said but I think it was something about watering a plant bc I mean if you don’t water a plant constantly it will die and if you constantly break promises whatever relationship you have will also break or die. I got a good grade so I hope this helps if you decide to use it :)
