it is not private, it is personal. i previously had this exercise and i answered: "that is not private, it is personal and was marked wrong.
how are these two answers different. and if "that" is wrong how would it be said in Greek other than "Αυτό"
I think "that" might have been correct but without context can't be sure. It may have been overlooked. If you can recall the sentence let us know.
it was this same sentence which I got marked wrong for answering "that is not private" instead of " it is not private" they are the same I think in English.
