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: Former Marine and Defense Intelligence Agency spy Robert McCall now lives in a diverse apartment complex in urban Massachusetts. He is working as a Lyft driver and assists the less fortunate with the help of his close friend and former CIA colleague, Susan Plummer. McCall travels to Istanbul by train to retrieve a local bookstore owner's daughter who was kidnapped by her father. He also helps Sam Rubinstein, an elderly Holocaust survivor who is looking for a painting of his sister; the two siblings were separated when they were transported to different camps by the Nazis, but the painting has been auctioned off and Sam cannot prove that he owns it. After discovering that the apartment courtyard has been vandalised, McCall accepts an offer from Miles Whittaker, a young resident with an artistic but troubled background, to repaint the walls. At some point, McCall rescues Miles, who had been lured away by a gang to commit crimes for them.
One day, Susan and DIA operative Dave York, McCall's former teammate, are called to investigate the apparent murder-suicide of an agency affiliate and his wife in Brussels. When the two separate after reaching their hotel, Susan is accosted and killed in an apparent robbery by two men who got off the elevator on her floor. When he receives the news, McCall begins to investigate both her death and the case she was working on. After reviewing CCTV footage, McCall determines that the suspects' foreknowledge of her floor and the expertly-delivered fatal stab suggest that she was targeted. He also confirms that the incident Susan was looking into was staged to look like a murder-suicide, and that Susan's death is probably connected to it. McCall makes contact with his former partner, York, who had thought him dead for years, and informs him of his findings.
A:
