Problem: Background: Sir Richard Starkey  (born 7 July 1940), known professionally as Ringo Starr, is an English musician, songwriter, singer, and actor who gained worldwide fame as the drummer for the Beatles. He occasionally sang lead vocals, usually for one song on an album, including "With a Little Help from My Friends", "Yellow Submarine", "Good Night", and their cover of "Act Naturally". He also wrote the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying". Starr was twice afflicted by life-threatening illnesses during childhood, and he fell behind in school as a result of prolonged hospitalisations.
Context: When Starr married Maureen Cox in 1965, Beatles manager Brian Epstein served as best man, with Starr's stepfather Harry Graves and fellow Beatle George Harrison as witnesses. Soon afterwards, the couple's matrimony became the subject of a US novelty song, "Treat Him Tender, Maureen", by the Chicklettes. Starr and Maureen had three children together: Zak (born 13 September 1965), Jason (born 19 August 1967) and Lee (born 11 November 1970). In 1971, Starr purchased Lennon's former home, Tittenhurst Park at Sunninghill in Berkshire and moved his family there. Following Starr's repeated infidelities, the couple divorced in 1975. Maureen died from leukaemia at age 48 in 1994.  In 1980, while on the set of the film Caveman, Starr met actress Barbara Bach; they were married on 27 April 1981. In 1985, he was the first of the Beatles to become a grandfather upon the birth of Zak's daughter, Tatia Jayne Starkey. Zak Starkey is also a drummer, and during his father's regular absences, he spent time with The Who's Keith Moon. Zak has performed with his father during some All-Starr Band tours. In total, Ringo Starr has eight grandchildren - one from Zak, four from Jason and three from Lee. In 2016, he was the first Beatle to become a great-grandfather.  Starr and Bach split their time between homes in Cranleigh, Surrey; Los Angeles; and Monte Carlo. In the Sunday Times Rich List 2011, Starr was listed at number 56 in the UK with an estimated personal wealth of PS150 million. In 2012, Starr was estimated to be the wealthiest drummer in the world. In 2014 Starr announced that his 200-acre Surrey estate at Rydinghurst, with its Grade II-listed Jacobean house, was for sale. However, he retains a property in the London district of Chelsea off King's Road, and he and Bach continue to divide their time between London and Los Angeles.  In December 2015, Starr and Bach auctioned some of their personal and professional items to the public via Julien's Auctions in Los Angeles. Highlights of the collection included Starr's first Ludwig Black Oyster Pearl drum kit; instruments given to him by Harrison, Lennon and Marc Bolan; and a first-pressing copy of the Beatles' White Album numbered "0000001". The auction raised over $9 million, a portion of which was set aside for the Lotus Foundation, a charity founded by Starr and Bach.  In 2016, Starr expressed his support for the United Kingdom's withdrawal from the European Union, explaining: "I thought the European Union was a great idea, but I didn't see it going anywhere lately." In 2017 he described his impatience for Britain to "get on with" Brexit, declaring that "to be in control of your country is a good move."

Answer: In 1980, while on the set of the film Caveman, Starr met actress Barbara Bach; they were married on 27 April 1981.

Background: Ai Weiwei (Chinese: Ai Wei Wei ; pinyin: Ai Weiwei,  English pronunciation ; born 28 August 1957 in Beijing) is a Chinese contemporary artist and activist. His father's (Ai Qing) original surname was written Jiang (Jiang ). Ai collaborated with Swiss architects Herzog & de Meuron as the artistic consultant on the Beijing National Stadium for the 2008 Olympics.
Context: On 22 June 2011, the Chinese authorities released Ai from jail after almost three months' detention on charges of tax evasion. Beijing Fa Ke Cultural Development Ltd. (Chinese: Bei Jing Fa Ke Wen Hua Gong Si ), a company Ai controlled, had allegedly evaded taxes and intentionally destroyed accounting documents. State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he is prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of the government. On 23 June 2011, professor Wang Yujin of China University of Political Science and Law stated that the release of Ai on bail shows that the Chinese government could not find any solid evidence of Ai's alleged "economic crime". On 24 June 2011, Ai told a Radio Free Asia reporter that he was thankful for the support of the Hong Kong public, and praised Hong Kong's conscious society. Ai also mentioned that his detention by the Chinese regime was hellish (Chinese: Jiu Si Yi Sheng ), and stressed that he is forbidden to say too much to reporters.  After his release, his sister gave some details about his detention condition to the press, explaining that he was subjected to a kind of psychological torture: he was detained in a tiny room with constant light, and two guards were set very close to him at all times, and watched him constantly. In November, Chinese authorities were again investigating Ai and his associates, this time under the charge of spreading pornography. Lu was subsequently questioned by police, and released after several hours though the exact charges remain unclear. In January 2012, in its International Review issue Art in America magazine featured an interview with Ai Weiwei at his home in China. J.J. Camille (the pen name of a Chinese-born writer living in New York), "neither a journalist nor an activist but simply an art lover who wanted to talk to him" had travelled to Beijing the previous September to conduct the interview and to write about his visit to "China's most famous dissident artist" for the magazine.  On 21 June 2012, Ai's bail was lifted. Although he is allowed to leave Beijing, the police informed him that he is still prohibited from traveling to other countries because he is "suspected of other crimes," including pornography, bigamy and illicit exchange of foreign currency. Until 2015, he remained under heavy surveillance and restrictions of movement, but continues to criticize through his work. In July 2015, he was given a passport and may travel abroad.
