Definition: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: 1974, the present. Dorothy Yates lives with her husband Edmund in an isolated farmhouse in Haslemere, Surrey. They have just been released from a mental institution to which they were committed in 1957 after it was found Dorothy was a cannibal who killed and partially ate at least six people. It is later revealed that her cannibalism can be understood as an attempt to cope with a childhood trauma when she found out that she had eaten parts of her pet rabbit that her parents had cooked and served as dinner. Although her husband Edmund was convicted, it is later revealed that he only faked his dementia in order to remain with his wife. He is a truly devoted husband who loves his wife dearly and does not take part in the actual acts of murder in 1957 and in the present, only helping in covering them up. Now, it seems as if Dorothy has had a severe relapse. She secretly lures lonely young people to her home, promising tea and a tarot card reading, only with the sessions ending with a violent murder and "feast".  
Jackie, Edmund's daughter by previous marriage, lives in London but secretely visits her dad and stepmum at night to bring her parcels containing animal brain, thereby implicitly feigning to commit murders for her so as to contain Dorothy's murderous urges. At the same time, Jackie tries to control her 15-year-old stepsister Debbie, Dorothy's actual daughter that she and Edmund had shortly before being committed to the asylum. Debbie has been recently thrown out of the orphanage. She now stays with Jackie and rides with her boyfriend Alec, head of a violent biker gang. Debbie incites Alec to start a fight with a barman in one of London's hip nightclubs because he denied her liquor due to her being underage. When they get thrown out, the bike gang later ambush and assault the barman with a chain but leave when spotted. Debbie, however, decides to stay behind and hides the body in the trunk of a car before the police arrive.
Output:
Who does Alec's girlfriend stay with?
