Problem: Background: Rabindranath Tagore FRAS ( ( listen); Bengali: [robindronath thakur]), also written Ravindranatha Thakura (7 May 1861 - 7 August 1941), sobriquet Gurudev, was a Bengali polymath who reshaped Bengali literature and music, as well as Indian art with Contextual Modernism in the late 19th and early 20th centuries. Author of Gitanjali and its "profoundly sensitive, fresh and beautiful verse", he became in 1913 the first non-European to win the Nobel Prize in Literature. Tagore's poetic songs were viewed as spiritual and mercurial; however, his "elegant prose and magical poetry" remain largely unknown outside Bengal.
Context: In 1901 Tagore moved to Santiniketan to found an ashram with a marble-floored prayer hall--The Mandir--an experimental school, groves of trees, gardens, a library. There his wife and two of his children died. His father died in 1905. He received monthly payments as part of his inheritance and income from the Maharaja of Tripura, sales of his family's jewellery, his seaside bungalow in Puri, and a derisory 2,000 rupees in book royalties. He gained Bengali and foreign readers alike; he published Naivedya (1901) and Kheya (1906) and translated poems into free verse.  In November 1913, Tagore learned he had won that year's Nobel Prize in Literature: the Swedish Academy appreciated the idealistic--and for Westerners--accessible nature of a small body of his translated material focused on the 1912 Gitanjali: Song Offerings. He was awarded a knighthood by King George V in the 1915 Birthday Honours, but renounced it after the 1919 Jallianwala Bagh massacre.  In 1921, Tagore and agricultural economist Leonard Elmhirst set up the "Institute for Rural Reconstruction", later renamed Shriniketan or "Abode of Welfare", in Surul, a village near the ashram. With it, Tagore sought to moderate Gandhi's Swaraj protests, which he occasionally blamed for British India's perceived mental -- and thus ultimately colonial -- decline. He sought aid from donors, officials, and scholars worldwide to "free village[s] from the shackles of helplessness and ignorance" by "vitalis[ing] knowledge". In the early 1930s he targeted ambient "abnormal caste consciousness" and untouchability. He lectured against these, he penned Dalit heroes for his poems and his dramas, and he campaigned--successfully--to open Guruvayoor Temple to Dalits.
Question: Did he write books?
Answer: he published Naivedya (1901) and Kheya (1906) and translated poems into free verse.

Problem: Background: Javier Adelmar Zanetti was born in Buenos Aires with Italian origins to working-class parents and grew up in the harbour area in the Dock Sud district, one of the city's most notorious areas. His father Rodolfo was a bricklayer and his mother Violeta Bonnazola was a cleaner. He began playing football on a field in the city suburbs, maintaining the pitch in his spare time. When he was a teenager, he tried out for local club Independiente's youth academy but was ultimately rejected and told that he lacked the physique to succeed in the game.
Context: On 20 October 2010, at 37 years and 71 days, Zanetti became the oldest player to score in the Champions League when he netted in the opening minute of Inter's 4-3 group stage win over Tottenham Hotspur at the San Siro. This was only his second ever Champions League goal; his first came in December 1998 in a match in a 2-0 win against Sturm Graz. He scored one of Inter's goals in their 3-0 win against Seongnam Ilhwa Chunma at the 2010 FIFA Club World Cup, which they eventually won, although Inter missed out on the UEFA Super Cup that season.  On 19 January 2011, Zanetti overtook Inter legend Giuseppe Bergomi in Serie A appearances, his 520th match in Serie A, all for Inter. On 11 May 2011, Zanetti made his 1,000th appearance as a professional footballer playing for Inter against Roma in the second leg of the Coppa Italia semi-final. On 20 September 2011, Zanetti made the all-time appearance record in a Serie A clash against Novara, surpassing Giuseppe Bergomi.  On 10 March 2013, Zanetti played in his 600th Serie A match for Inter, a 1-0 loss to Bologna at the San Siro. On 21 April 2014, in the 1-0 home win against Parma, Zanetti played his 1,100th official match and became the player with the fourth-most appearances of all time.  On 29 April 2014, Inter chairman Erick Thohir announced that Zanetti would retire at the end of the 2013-14 season and become a club director. Zanetti's last competitive match at the San Siro was a 4-1 victory over Lazio on 10 May 2014. He came on as a substitute for Jonathan in the 52nd minute and wore a special armband featuring the names of every player he had played with during his career at Inter. He retired after the last game of the season, which he started as centre-back in a 2-1 away defeat to Chievo on 18 May.
Question: Why did he retire
Answer: oldest player

Problem: Background: Ai Kago (Jia Hu  Ya Yi , Kago Ai), born February 7, 1988 in Yamatotokada, Nara, Japan, is a Japanese singer, actress, author, and former Guinness World Record holder. Kago began her career at the age of 12 as a member of the idol group Morning Musume. In the same year, she became a founding member of Minimoni.
Context: Throughout the second half of 2010, Kago became unhappy with the direction of her work. Around the same time, she began dating restaurant owner Haruhiko Ando, who acted as an in-between for her agency and herself. Since beginning a relationship with Ando, Kago cancelled several jobs at the last minute, causing her agency to suspend her activities. Despite this, she participated in a live performance and opened a separate blog without permission.  Kago parted ways with R&A Promotions in November 2010 despite her contract ending in March 2013. As a response, in 2011, Kazuyuki Ito, president of Mainstream (an associate of R&A Promotions), declared that the agency planned on suing for 100 million yen in damages for contract violations. During that time, Kago's career was also derailed by her personal life. In September 2011, Ando was arrested for alleged extortion and claiming to have connections with the yakuza. In the same month, Kago was rushed to a nearby hospital after agency officials found her on the floor of her apartment with cuts to her wrists. Her life was reported to be not in danger, though there were speculations that it was a planned suicide. Following the incident, she and Ando registered their marriage, and Kago became pregnant.  After spending 2012 out of the public eye with the birth of her daughter, Minami, Kago transferred to a new agency in 2013. Planning to revive her music career, she formed an idol group, which was later named Girls Beat!! The group would be crowd-sourced using lyrics, music, and costume ideas submitted by fans. Remi Kita and Ryona Himeno were recruited as the other two members after passing the auditions.  Girls Beat!! released their first single, "Sekai Seifuku" on July 22, 2014. Their activities were abruptly put on hold when an arrest warrant was put out for Ando in October on suspicions of loaning money at illegal interest rates. Kago later filed for divorce, planning to continue activities once the divorce was finalized. Although Kago was eventually successful in doing so, in August 2015, her contract with her agency expired, though she continued activities with Girls Beat!! in November. On February 29, 2016, she graduated from the group.
Question: what happened in 2011?
Answer:
In September 2011, Ando was arrested for alleged extortion and claiming to have connections with the yakuza.
