Given the task definition and input, reply with output. 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.

Passage: Ivanhoe "Ivan" Martin is a poor Jamaican man in search of a job. He leaves his rural home after his grandmother dies to live with his impoverished mother in Kingston. He meets Jose, who takes him to see Django, a Spaghetti Western. Excited by urban life, he tries to get work but fails. He finally gets a job with a preacher, he also takes a broken bicycle frame and rebuit it into a working bicycle, and uses it to run errands for a record producer. He gets into trouble with the preacher after he used his church for secular songs. After being fired by preacher he returned to the house to collect his bicycle, that preacher had now officially given to Ivan's colleague, the two fight after he refuses to give Ivan the cycle; Ivan slashes him with a knife, a crime for which he is sentenced to a whipping.
Ivan interests the record producer in a song he writes and performs, "The Harder They Come", but he only gets $20 for it. He dreams of stardom, but the stranglehold the producer has on the music industry condemns Ivan to work for a pittance. Eventually Jose offers him an opportunity dealing marijuana, moving the drug from the country to the city on a motorbike. When Ivan complains about the pay and conditions, Jose informs on him to the police. On his next trip, when a policeman tries to flag Ivan to stop, he panics and shoots the officer.
Next, Ivan meets a woman in a hotel. While he is in bed with her, the police surround the room and try to capture him. He shoots his way out, killing three officers. On the run, he returns to shoot and wound the girl he slept with, believing she and Jose betrayed him. He then finds Jose and pursues him, shooting at him, but Jose escapes.
Who does Ivan attack with a knife?
