JessicaWin..., I think your reply was, 'NOT OKAY!' Lelouch, like myself, was simply asking, Is the translation correct. No need to be shouted at! If, someone said to me, ''You know the newspaper.'' I would hear that as a question, i.e. there should be a ''?'' at the end. So, YES, we know it is German but, what does it mean in English if, 'Du kennst die Zeitung.', is not a question?
If anyone has a constructive reply ...
I think the problem is that the sentence sounds like a question but there is no '?'-symbol. You, yourself, have ''hit the nail on the head'' with your suggested comparison of, ''you know the internet?" Here you automatically but a '?' symbol at the end and this makes your meaning perfectly clear.
I have not looked at the hints! If asked, ''Do you know 'xyz' ?'' Yes, I might use the word 'acquainted' in my reply. And, I may use the word 'acquainted' in a question to another. ( It would depend upon whom I was conversing with!? ) To me, here, 'acquainted' has a meaning of, familiarity, 'knowing', awareness; ''being aware of'', etc.
What I think is really in question with this translation is, ''Is it a statement or a question.'' If it is a statement; then its English translation reads strangely and I do not know what it is saying. Or, if it is a question then where are the ?-symbols.
