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.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
Passage: Ladies' man and amateur crime solver Gay Laurence, the "Gay Falcon", reluctantly agrees to give up both habits to mollify his fiancée, Elinor Benford. He and his uncouth sidekick, Jonathan "Goldie" Locke, become unenthusiastic stockbrokers. When Elinor asks him to attend a party given by Maxine Wood to mingle with potential clients, he refuses to go to that much trouble.
However, when Wood asks for his help via pretty assistant Helen Reed, he cannot resist. It seems that Wood's soirées have been plagued by jewel thefts, and she is particularly worried about the diamond of her guest, Vera Gardner.
At the party, Elinor becomes annoyed when she figures out why Gay changed his mind about attending, and retaliates by dancing with Manuel Retana. In frustration, she grabs the flower from Retana's lapel and flings it at Gay. He calmly picks it up and attaches it to his lapel. Vera Gardner then insists on dancing with Gay; she hands him her diamond secretly, much to his puzzlement, then leaves the room. Moments later, a shot rings out, and she is dead. The killer is seen by Goldie as he makes his getaway.
Police Detectives Bates and Grimes take Goldie to the police station on suspicion of murder. Gay persuades Inspector Mike Waldeck to release Goldie so he can flush out the real murderer. Then he and Helen go to see Maxine, leaving Goldie in the car. While they are gone, Goldie is abducted by Noel Weber, Gardner's killer. Weber orders Goldie to call Gay to offer to trade Goldie's life for the diamond. However, Weber is shot, and once again, Goldie is found by the police near a dead body.
Answer:
Who is worried about the diamond of Vera Gardner?
