input question: Generate a question that has the following answer: He tries to strangle her and threatens to put her son in gay prostitution. for the following movie plot: Liz is a Los Angeles street prostitute. The audience first sees her attempting to get a customer on a busy downtown street near a tunnel. She addresses the audience directly on her life and problems throughout the film. When a van stops by, she gives it the brush off, recalling the last time she serviced a man in a van: it turned out there were several other men in the van, who gang-raped her and left her for dead. A passerby gives her his handkerchief and offers to take her to a hospital. She refuses, makes up a boyfriend story and asks for some money. She sends him the money back with a thank you note and a new handkerchief. Liz isn't merely attempting to get a customer, however: she is attempting to escape her pimp, Blake. Blake is a well-dressed, businesslike and extremely controlling man. As Liz stops off at a strip club for a drink, she explains how she ended up as she did: she was a small town girl, who married a violent drunk named Charlie (Frank Smith). Though they have a child together, she can no longer take it and leaves him, taking her son with her, as he's sleeping it off. She takes a job on the graveyard shift at a diner, and when a customer offers her more money to have sex with him, she decides, given her rather low pay, to take it. She does this independently for a time until she meets Blake, who takes her to LA. Though Blake does do some things for her (including getting her tattooed), he is ultimately as cruel as her husband, so she decides to escape from him. A local homeless person/street performer named Rasta decides to treat Liz to a movie. Though Rasta is a bit scary (his act involves walking on broken glass), Liz agrees. At this point the scenes of Liz and Rasta at the movie are intercut with Blake explaining his life to the audience, giving the impression that Liz and Rasta are watching Blake's soliloquy. After the movie, Liz talks to the audience about her son, whom she clearly loves, though he's now in foster care. She finally gets a customer and services him. He has a heart...???
output answer: What does Blake do to Liz when she tries to stop him?

Generate a question that has the following answer: Michelle for the following movie plot: Following up on the surprise success of their micro-budget production THE PUFFY CHAIR (2005), brothers Jay and Mark Duplass turn their handheld DV camera toward skewering the pretentiousness of the independent film world while tossing in a few horror film scares for good measure. The result is entertaining and unique, with enough laughs, insight, and excitement for adventurous viewers. After seeing the accolades heaped up on a colleague for his laughable film (WE ARE NAKED) at a Los Angeles film festival, Matt (Ross Partridge) decides that he can do better. With his sometime girlfriend, Catherine (Elise Muller), and friends Michelle (Greta Gerwig, HANNAH TAKES THE STAIRS) and Chad (Steve Zissis) in tow, they immediately set off to a cabin in the woods for the weekend to create the film that will make them all famous on the festival circuit. While Chad focuses his energy on winning the affections of uninterested Michelle, Matt comes up with the cinematic construct of a stranger with a paper bag on his head terrorizing a group of people in the woods. After the initial evening of alcoholic brainstorming, though, the idea becomes reality, and the friends' relationships are tested as they find themselves in a truly scary situation. The idea for BAGHEAD was hatched on the set of the THE PUFFY CHAIR when, during a discussion requesting those involved to think of the scariest thing imaginable, someone said, "A guy with a bag on his head staring into your window." Though it may be a flimsy starting point for a film, the Duplasses surround the idea with a believable cast, truthful insight into relationships, and a few genuine chills. The result is clever, funny, and refreshingly difficult to classify.

Answer: Who does Chad have a romantic interest in?

Problem: Given the question: Generate a question that has the following answer: Watching TV. for the following movie plot: The plot alternates between events immediately following the death of Robert (Anthony Hopkins), a brilliant mathematician whose genius was undone by crippling mental illness, and flashbacks revealing the life he shared with his daughter Catherine (Gwyneth Paltrow). Catherine is also a mathematician, but she struggles with living in her father's shadow, with balancing her demanding studies with caring for her father and also with the fear that she may have inherited his mental illness. At home, Robert clings to sanity by constantly bombarding Catherine with complex mathematical problems. In the opening scene Robert startles Catherine while she watches TV in the middle of the night. He gives her a bottle of champagne for her birthday, and they chat for a while about the nature of insanity, ending with the revelation that Robert died last week and his funeral is tomorrow. Awakened from this dream, Catherine realizes that Hal (Jake Gyllenhaal), a former graduate student of Robert's, is still upstairs, reading through Robert's books. Robert filled many notebooks with meaningless notes. Hal believes that Robert's genius may have withstood his illness, and clues to that genius might lie among the gibberish of his notebooks. When Hal comments on the vast amount of work Robert did, a suspicious Catherine searches Hal's backpack. Though Catherine finds nothing in Hal's bag, a notebook falls out of his coat. He explains that he wanted to give the notebook as a birthday present because it "had something written in it about her, not math, her". Hal is forced to leave, giving the notebook as intended, when Catherine calls the police. The next day, for the funeral, Catherine's sister Claire (Hope Davis) arrives in town. A huge contrast to the unkempt Catherine, Claire is an overly put together, neurotic New Yorker. Relations between the sisters are tense, and Catherine cannot stand her sister's constant harping on matters of appearance. Catherine is also upset that Claire didn't care for her father as much as Catherine did...
