"Do you wear shoes?"
Translation:Tu porți pantofi?
"Do you wear shoes?" could be translated to Romanian as:
"(Tu) porți pantofi?", where "tu" is the second person singular
"(Voi) purtați pantofi?", where "voi" is the second person plural
"(Dumneavoastră) purtați pantofi?", where "dumneavoastră" is the (very) polite version of the second person, and the number (singular vs plural) is given by the context.
Also, make sure you put the question mark at the end of each question, as I noticed that Duolingo sometimes refuses the answer if the "?" is missing.
