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.

Example Input: Passage: By the time Hope was exhibited, Watts had already committed himself to donate his most significant works to the nation, and although he received multiple offers for the painting he thought it inappropriate not to include Hope in this donation, in light of the fact that it was already being considered one of his most important pictures. In mid-1886 Watts and his assistant Cecil Schott painted a duplicate of the piece, with the intention that this duplicate be donated to the nation allowing him to sell the original. Although the composition of this second painting is identical, it is radically different in feel. The central figure is smaller in relation to the globe, and the colours darker and less sumptuous, giving it an intentionally gloomier feel than the original.In late 1886 this second version was one of nine paintings donated to the South Kensington Museum (now the Victoria and Albert Museum) in the first instalment of Watts's gift to the nation. Meanwhile, the original was briefly displayed in Nottingham before being sold to the steam tractor entrepreneur Joseph Ruston in 1887. Its whereabouts was long unknown until in 1986 it was auctioned at Sotheby's for 869,000 (about 2,500,000 in 2019 terms), 100 years after its first exhibition.On their donation to the South Kensington Museum, the nine works donated by Watts were hung on the staircase leading to the library, but Hope proved a popular loan to other institutions as a symbol of current British art. At the Royal Jubilee Exhibition of 1887 in Manchester, an entire wall was dedicated to the works of Watts. Hope, only recently completed but already the most famous of Watts's works, was placed at the centre of this display. It was then exhibited at the 1888 Melbourne Centennial Exhibition and the 1889 Exposition Universelle in Paris, before being moved to Munich for display at the Glaspalast. In 1897 it was one of the 17 Watts works transferred to the newly created National Gallery of British Art (commonly known as the Tate Gallery, now Tate Britain); at the time, Watts was so highly regarded that an entire room of the new museum was dedicated to his works. The Tate Gallery considered Hope one of the highlights of their collection and did not continue the South Kensington Museum's practice of lending the piece to overseas exhibitions.
Example Output: What is the last name of the person who wanted to donate a duplicate to the nation so he could sell the original?

Example Input: Passage: Tom Hepple, a geologist, and Gerri Hepple, a counsellor, are an older married couple who have a comfortable, loving relationship. The film observes them over the course of the four seasons of a year, surrounded by family and friends who mostly suffer some degree of unhappiness. Gerri's friend and colleague, Mary, works as a receptionist at the health centre. She is a middle-aged divorcee seeking a new relationship, and despite telling everyone she is happy, appears desperate and depressed. She often seems to drink too much. The Hepples' only child, Joe, is 30 and unmarried and works as a solicitor giving advice on housing.
In the summer, the Hepples are visited by Ken, Tom's old friend from his student days. Ken is overweight, eats, smokes and drinks compulsively and seems very unhappy. Tom and Gerri host a barbecue in Ken's honour. Mary drives her newly bought car to the party, but gets lost and arrives late. Having had some wine, she flirts with Joe, whom she has known since he was a child. He remains friendly but does not reciprocate the flirtation. After the party, Mary reluctantly gives Ken a lift to the train station. He makes a clumsy romantic advance and Mary irritably rejects him.
Months later, in the autumn, Mary is once again at Tom and Gerri's home. Joe arrives with a new girlfriend, Katie. Mary appears rude and hostile towards Katie, which is not appreciated by Tom and Gerri. This creates a rift between Gerri and Mary.
In the winter, Tom, Gerri, and Joe attend the funeral for the wife of Tom's brother, Ronnie. Towards the end of the service, Ronnie's estranged son, Carl, arrives, and angrily asks why the ceremony was not delayed for him. At the reception at Ronnie's house, Carl becomes aggressive and walks out. Tom and Gerri invite Ronnie back to London to stay with them for a while and Ronnie agrees.
Example Output: Who flirts with Tom's child?

Example Input: Passage: Detective Mike Hoolihan is investigating the murder of Jennifer Rockwell, an astrophysicist at an observatory in New Orleans. She had presented a talk on black holes in the evening, but was found dead in the morning by the manager of the observatory. She had been shot in the face, but there was no weapon. There is a sock and a jar of moisturizing cream found at the scene.
The manager claims that he was out all night with an associate. The sock is traced to Jennifer's boyfriend, who claims he left hurriedly to work on a new theory.
Jennifer's home is full of tchotchkes and other old nick-nacks. Mike passes out when she picks up a Florida snow globe, and imagines unique blue marbles similar to one that is on a string around her neck. When she comes to, she talks about the marble, and how she doesn't remember where it came from. She was an orphan, and has always had it.
Her co-investigator and supervisor suggest that this looks like "The .38 Caliber Killer", who killed young women, but hadn't struck in many years. The murderer always exchanged nick nacks with his victims.
While doing a more detailed search of the area, Mike finds a gun in a case, and a red scarf she had been having dreams about. The gun, a .38 revolver, is traced to the observatory manager, who admits he found it, and tried to dispose of it so he wouldn't be a suspect.
Figuring from where the gun originally lay, Mike concludes that Jennifer had shot herself. The investigators agree.
In photos of the crime scene, Mike realizes that there are no photos of the jar of moisturizing cream that she noted. When she buys a jar of the cream, she reacts as if memories come flooding back.
Example Output:
What is the last name of the person whose boyfriend owned the sock?
