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.
Input: Passage: In contemporary wartime San Francisco, chemist and blackmailer Albert Baker is killed by hit man Philip Raven, who recovers a stolen chemical formula. Raven is double-crossed by his employer, Willard Gates who pays him with marked bills and reports them to the Los Angeles Police Department as stolen from his company, Nitro Chemical Corporation of Los Angeles. Raven learns of the setup and decides to get revenge. LAPD detective lieutenant Michael Crane, who is vacationing in San Francisco to visit his girlfriend, nightclub singer Ellen Graham, is immediately assigned the case. He goes after Raven, but the assassin eludes him.
Meanwhile, Gates hires Ellen to work in his LA nightclub after an audition where she sings and performs magic tricks. Then she is taken to a clandestine meeting with Senator Burnett, where she learns that Gates and Nitro Chemical are under investigation as suspected traitors, and is recruited to spy on Gates. Unknown to each other, she and Gates board a train for Los Angeles, followed by Raven. By chance, Raven and Ellen sit next to each other. The next morning, Gates is alarmed when he sees them asleep with Raven's head on her shoulder. He wires ahead to alert the police, but Raven forces Ellen at gunpoint to help him elude them again. He is about to kill her but is interrupted by workmen, allowing Ellen to flee. From Gates's club, she tries to contact Crane, but he has left San Francisco to return to LA.
