Hi, <br/><br/>A: Who is she?<br/><br/> B : She is Sarah.<br/><br/> A: What is she?<br/><br/> B: She is a nurse.<br/><br/>Who is for people.<br/><br/>What is for things.<br/><br/>Can you ask someone you meet for the first time "What are you?" meaning "What's your job?" <br/><br/>Isn't it more natural to say "What do you do?" or simply "What's your job?"<br/><br/>Thanks.
