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.

Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.
Who finds the shipping magnate's opera tickets?

Passage: Harrison married model Pattie Boyd on 21 January 1966, with McCartney serving as best man. Harrison and Boyd had met in 1964 during the production of the film A Hard Day's Night, in which the 19-year-old Boyd had been cast as a schoolgirl. They separated in 1974 and their divorce was finalised in 1977. Boyd said her decision to end the marriage was due largely to George's repeated infidelities. The last infidelity culminated in an affair with Ringo's wife Maureen, which Boyd called "the final straw". She characterised the last year of their marriage as "fuelled by alcohol and cocaine", and she stated: "George used coke excessively, and I think it changed him ... it froze his emotions and hardened his heart." She subsequently moved in with Eric Clapton, and they married in 1979.Harrison married Dark Horse Records' secretary Olivia Trinidad Arias on 2 September 1978. They had met at the A&M Records offices in Los Angeles in 1974, and together had one son, Dhani Harrison, born on 1 August 1978.He restored the English manor house and grounds of Friar Park, his home in Henley-on-Thames, where several of his music videos were filmed including "Crackerbox Palace"; the grounds also served as the background for the cover of All Things Must Pass. He employed ten workers to maintain the 36-acre (15 ha) garden. Harrison commented on gardening as a form of escapism: "Sometimes I feel like I'm actually on the wrong planet, and it's great when I'm in my garden, but the minute I go out the gate I think: 'What the hell am I doing here?'" His autobiography, I, Me, Mine, is dedicated "to gardeners everywhere". The former Beatles publicist Derek Taylor helped Harrison write the book, which said little about the Beatles, focusing instead on Harrison's hobbies, music and lyrics. Taylor commented: "George is not disowning the Beatles ... but it was a long time ago and actually a short part of his life."Harrison had an interest in sports cars and motor racing; he was one of the 100 people who purchased the McLaren F1 road car. He had collected photos of racing drivers and their cars since he was young; at 12 he had attended his first race, the 1955 British Grand Prix at Aintree. He wrote "Faster" as a tribute to the Formula One racing drivers Jackie Stewart and Ronnie Peterson. Proceeds from its release went to the Gunnar Nilsson cancer charity, set up after the Swedish driver's death from the disease in 1978. Harrison's first extravagant car, a 1964 Aston Martin DB5, was sold at auction on 7 December 2011 in London. An anonymous Beatles collector paid £350,000 for the vehicle that Harrison had bought new in January 1965.
What were the last names of the two people who were married and McCartney was the best man?

Passage: Chartwell is a country house near the town of Westerham, Kent in South East England. For over forty years it was the home of Winston Churchill. He bought the property in September 1922 and lived there until shortly before his death in January 1965. In the 1930s, when Churchill was excluded from political office, Chartwell became the centre of his world. At his dining table, he gathered those who could assist his campaign against German re-armament and the British government's response of appeasement; in his study, he composed speeches and wrote books; in his garden, he built walls, constructed lakes and painted. During the Second World War Chartwell was largely unused, the Churchills returning after he lost the 1945 election. In 1953, when again Prime Minister, the house became Churchill's refuge when he suffered a devastating stroke. In October 1964, he left for the last time, dying at his London home, 28, Hyde Park Gate, on 24 January 1965.
The origins of the estate reach back to the 14th century; in 1382 the property, then called Well-street, was sold by William-at-Well. It passed through various owners and in 1836 was auctioned, as a substantial, brick-built manor. In 1848, it was purchased by John Campbell Colquhoun, whose grandson sold it to Churchill. The Campbell Colquhouns greatly enlarged the house and the advertisement for its sale at the time of Churchill's purchase described it as an "imposing" mansion. Between 1922 and 1924, it was largely rebuilt and extended by the society architect Philip Tilden. From the garden front, the house has extensive views over the Weald of Kent, "the most beautiful and charming" Churchill had ever seen, and the determining factor in his decision to buy the house.
In 1946, when financial constraints forced Churchill to again consider selling Chartwell, it was acquired by the National Trust with funds raised by a consortium of Churchill's friends led by Lord Camrose, on condition that the Churchills retain a life-tenancy. After Churchill's death, Lady Churchill surrendered her lease on the house and it was opened to the public by the Trust in 1966. A Grade I listed building, for its historical significance rather than its architectural merit, Chartwell has become among the Trust's most popular properties; some 232,000 people visited the house in 2016, the fiftieth anniversary of its opening.

What was the last month Winston Churchill lived at Chartwell?
