Task: Question Answering
Input (English): Passage: Robert and Cathy Wilson (Robert Donat and Deborah Kerr) are a timid married couple in 1940 London. He is a bookkeeper, she a bored housewife. However, their tedium-filled lives are drastically changed by the war. He enlists in the Royal Navy, while she (against his wishes) joins the Wrens. During the three years the couple are apart, they are transformed, each becoming much more self-confident.
Cathy's assertive new friend, Dizzy Clayton, helps her break out of her shell. She begins going out with Dizzy's cousin, naval architect Richard, who falls in love with her. However, she remains faithful (if unenthusiastically) to her husband.
Meanwhile, Robert toughens up on sea duty and in time becomes a petty officer. His hands are badly burned when his ship is sunk, but he stoically rows in the lifeboat for five days without complaint. He recuperates in a hospital, tended by Elena, a beautiful nurse. On the last night of his stay, he asks her out to dinner. He is attracted to her, but she informs him that she lost her beloved husband only six months earlier, kisses him, and leaves.
Robert and Cathy both receive ten-day leaves, but each dreads being reunited with the dowdy spouse each remembers and being forced back into the dreary life they shared. 
Question: What is the first name of the person who joins the Wrens?
Output (English): Cathy.
