Task: Question Answering
Input (English): Passage: Tom Stansfield is a researcher at a publishing company who works under the tyrannical Jack Taylor. Tom has a crush on his boss' daughter, Lisa, who is completely controlled by her overprotective father. She reveals to Tom that her father is making her house-sit the same night as a party she wants to attend, but Tom convinces her to stand up to her father and attend the party anyway. Lisa asks him to come to their house that night, leading Tom to think that she has invited him to the party; in reality, she just wants him to fill in for her - he reluctantly agrees.
A comedy of errors ensues, including the return of Lisa's older brother, Red, on the run from drug dealers. Red dumps drugs into the toilet, and instead returns a bag of flour to the drug dealer. One of Tom's tasks is to guard their owl, O-J, which lives in an open cage (it has not been able to fly due to a deep depression, from the loss of a prior mate). When the bird drinks from the toilet polluted with drugs, it flies away. Jack's ex-secretary Audrey goes to the house to try to earn her job back. After fighting with her boyfriend, she stays over at the house.
Lisa returns home after finding out that her boyfriend Hans is cheating on her. Tom hides from her everything that happened and she spends some time with her thinking he is homosexual. He clarifies to her that he's actually straight and she starts to like him. Audrey's friend thinks she has breast cancer and asks Tom to feel her breasts. Lisa walks in on them and is disgusted by the situation. 
Question: Who has a boyfriend named Hans?
Output (English): Lisa.
