Task: Question Answering
Input (English): Passage: Singing-and-dancing stage star Julie is told that husband Marty is reported missing in action during the Korean War. After a long waiting period, she makes plans to marry Vernon, who is Marty's best friend. After the marriage, Marty (who crashed but survived on an island) turns up at one of Julie's shows. Upon discovering Julie's new marriage, Marty demands his rights as her first husband.
Julie finds that she is legally married to both Marty and Vernon. She soon realises that she must choose who she wants to be with, if only to avoid being branded a bigamist. But Julie loves the idea of having two husbands and so she decides to try to live with them both, to the annoyance and disapproval of Marty and Vernon who both know that her idea will not work out.
Meanwhile, Julie's close friend Gwen has a secret crush on Marty and hopes to be with him, if only Julie could make her up mind as to who she wants. After a long serious decision and a talk with them both, Julie decides that she is more in love with Marty and she leaves Vernon, who has now fallen for Gwen. 
Question: Who is Julie's first husband?
Output (English): Marty.
