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: American sailor David Martens, on shore leave in England, visits his brother Jack's grave. He meets fashion designer Sally Meadows, who by coincidence works with Jack's ex-fiancée, Diana, a model.
Successful stylist Kingsley Beauchamp and financial backer Madame Dupont own the company where Sally and Diana are employed. Expensive jewels are to be worn by Diana when she models a new dress, but Beauchamp hires two men, Costard and Podd, to break into a safe after hours and steal the gems.
Diana stumbles on the robbery and Costard kills her. He knocks David unconscious and decides to frame him for the theft, crashing a car with David inside, reporting it stolen and placing a ruby bracelet in David's pocket.
While the police make David a prime suspect, Beauchamp and Costard dispose of Diana's body and the diamonds. They decide to murder David after he suspects them, using gas, but Sally saves him.
Diana's body is found in a river. David goes to Beauchamp's home and discovers the missing dress worn by Diana. He knows that Beauchamp is about to fly to Amsterdam, so he hurries to the airport. Costard is there, being double-crossed while Podd smuggles the jewels on Beauchamp's behalf. The police arrive in time to arrest all three.
Output:
Who frames the sailor?
