why is this wrong?
i do not know if the police followed you
It may have more to do with poliziotto meaning policeman.
right. But we say "police" - not "policeman" of "police officer".
You are correct. Thanks.
Police = polizia. Policeman/police officer = poliziotto.
I'd report it, and ask them to accept it, since they've allowed other sentences to leave out the word "has" in the previous lessons.
Cop doesn't work?
