Detailed Instructions: 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.
Q: Passage: Anthony is a man with an American father and a deceased Japanese mother living and working in Tokyo. One day his son is run over and killed by Yatsu, this film's version of "The Metal Fetishist". Shortly afterward Anthony begins to transform into metal. He discovers that the work of his scientist father may be the key to his transformation. In his father's house he discovers a secret room with files and papers detailing the Tetsuo Project as a way to turn people into androids. He also learns that his father met his mother while they each researched the project. Anthony's wife arrives but before she sees her transformed husband a S.W.A.T. team arrives and she is taken hostage. Anthony's transformation finishes its hold and he defeats the S.W.A.T. team with bullets fired from his body, but refrains from killing them. The severely injured team is extracted, but then killed by Yatsu.
