I realise you cannot avoid some confusion but it is impossible to know whether this "Pardon!" is the Romanian or the English. Previously I answered "Scuze!" and it was the wrong answer since the translation was Ro-Eng. This time it is Eng-Ro. I will live with this. It cannot be perfect.
You could say"Pardon me" but Duolingo doesn't accept that. The direct translation for Pardon would be "pardon me".
