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: Consider Input: 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.

Output: What were the last names of the two people who were married and McCartney was the best man?


Input: Consider Input: Passage: 4 is the fourth solo studio album by American singer Beyoncé. It was released on June 24, 2011 by Parkwood Entertainment and Columbia Records. Following a career hiatus that reignited her creativity, Beyoncé was inspired to create a record with a basis in traditional rhythm and blues that stood apart from contemporary popular music. Her collaborations with songwriters and record producers The-Dream, Tricky Stewart and Shea Taylor produced a mellower tone, developing diverse vocal styles and influences from funk, hip hop, and soul music.
Severing professional ties with father and manager Mathew Knowles, Beyoncé eschewed the music of her previous releases in favor of an intimate, personal album. 4's lyrics emphasize monogamy, female empowerment and self-reflection, a result of Beyoncé considering a maturer message to contend artistic credibility. In May 2011, Beyoncé submitted seventy-two songs to Columbia Records for consideration, twelve of which appeared on the standard edition.
4 was promoted in mid-2011 by television performances and festival appearances, such as Beyoncé's headlining Glastonbury Festival set. The album received generally positive reviews by music critics; several publications included it on their year-end lists. It was her fourth consecutive album to debut at number one on the US Billboard 200, and it also reached number one in Brazil, France, Ireland, South Korea, Spain, Switzerland and the United Kingdom. 4 spawned the international singles "Run the World (Girls)", "Best Thing I Never Had", "Party", "Love on Top" and "Countdown". "Love on Top" won the Grammy Award for Best Traditional R&B Performance at the 55th annual ceremony. As of December 2015, 4 has sold 1.5 million copies in the United States.

Output: What is the name of the person whose collaborations with songwriters and record producers The-Dream, Stewart, and Taylor produced a mellower tone, developing diverse vocal styles and influences from funk, hip hop and soul music?


Input: Consider Input: Passage: Another major influence in his work was the rise of interest in vernacular architecture. By the time Douglas moved to Chester, the black-and-white revival using half-timbering was well under way, and Douglas came to incorporate this style in his buildings in Chester and elsewhere. The black-and-white revival did not start in Chester, but it did become Chester's speciality. The first Chester architect involved in the revival had been Thomas Mainwaring Penson, whose first work in this genre was the restoration of a shop in Eastgate Street in the early 1850s. Other early Chester architects involved in the revival were T. A. Richardson and James Harrison and it came to be developed mainly by T. M. Lockwood and by Douglas. Part of Douglas's earliest work for the Grosvenor family, the entrance lodge to Grosvenor Park, used half-timbering in its upper storey; this is the first known use by Douglas of black-and-white. Other vernacular motifs were taken from earlier styles of English architecture, in particular, the Tudor style. These include tile-hanging, pargetting and massive brick ribbed chimney stacks. In this style, Douglas was influenced by the architects Nesfield and Shaw. Douglas also used vernacular elements from the continent, especially the late medieval brickwork of Germany and the Low Countries.A characteristic of Douglas's work is his attention to both external and internal detailing. Such detailing was not derived from any particular style and Douglas chose elements from whichever style suited his purpose for each specific project. His detailing applied particularly to his joinery, perhaps inspired by his experience in his father's workshop, and was applied both to wooden fittings and to the furniture he designed. A further Continental influence was his use of a Dutch gable. The most important and consistently used element in Douglas's vernacular buildings was his use of half-timbering, which was usually used for parts of the building. However, in the cases of Rowden Abbey and St Michael and All Angels Church, Altcar, the entire buildings were timber-framed.


Output: Half-timbering is a component of what type of architecture?
