Hi,
I think i just didn't understand the task. I thought i am to use informal style while giving my answers. You can give me another work if you want to be sure that i know this subject.
Dear instructor,
I apologize, but I believe I may have misunderstood the task requirements. I had thought informality of style was permitted within my responses. Please allow me to attempt a revised submission if you wish to confirm my knowledge on this subject.
