PROBLEM: Passage: A number of performers and groups, including several early leaders, have been recognized for their contributions to taiko performance. Daihachi Oguchi was best known for developing kumi-daiko performance. Oguchi founded the first kumi-daiko group called Osuwa Daiko in 1951, and facilitated the popularization of taiko performance groups in Japan.Seidō Kobayashi is the leader of the Tokyo-based taiko group Oedo Sukeroku Taiko as of December 2014. Kobayashi founded the group in 1959 and was the first group to tour professionally. Kobayashi is considered a master performer of taiko. He is also known for asserting intellectual control of the group's performance style, which has influenced performance for many groups, particularly in North America.In 1968, Seiichi Tanaka founded the San Francisco Taiko Dojo and is regarded as the Grandfather of Taiko and primary developer of taiko performance in the United States. He was a recipient of a 2001 National Heritage Fellowship awarded by the National Endowment for the Arts  and since 2013 is the only taiko professional presented with the Order of the Rising Sun 5th Order: Gold and Silver Rays by Emperor Akihito of Japan, in recognition of Grandmaster Seiichi Tanaka's contributions to the fostering of US-Japan relations as well as the promotion of Japanese cultural understanding in the United States.In 1969, Den Tagayasu (田耕, Den Tagayasu) founded Ondekoza, a group well known for making taiko performance internationally visible and for its artistic contributions to the tradition. Den was also known for developing a communal living and training facility for Ondekoza on Sado Island in Japan, which had a reputation for its intensity and broad education programs in folklore and music.Performers and groups beyond the early practitioners have also been noted. Eitetsu Hayashi is best known for his solo performance work. Hayashi joined Ondekoza when he was 19, and after parting from the group helped found Kodo, one of the best known and most influential taiko performance groups in the world. Hayashi soon left the group to begin a solo career and has performed in venues such as Carnegie Hall in 1984, the first featured taiko performer there. He was awarded the 47th Education Minister's Art Encouragement Prize, a national award, in 1997 as well as the 8th Award for the Promotion of Traditional Japanese Culture from the Japan Arts Foundation in 2001. 
Question: What group is known for its artistic contributions to the tradition?

SOLUTION: Ondekoza.

PROBLEM: Passage: At first, Baylis presented both drama and opera at each of her theatres.  The companies were known as the "Vic-Wells".  However, for both aesthetic and financial reasons, by 1934, the Old Vic had become the home of the spoken drama, while Sadler's Wells housed both the opera and a ballet company, the latter co-founded by Baylis and Ninette de Valois in 1930.Lawrance Collingwood joined the company as resident conductor alongside Corri.  With the increased number of productions, guest conductors were recruited, including Geoffrey Toye and Anthony Collins. The increasing success of the new ballet company helped to subsidise the high cost of opera productions, enabling a further increase in the size of the orchestra, to 48 players. Among the singers in the opera company were Joan Cross and Edith Coates. In the 1930s, the company presented standard repertoire operas by Mozart, Verdi, Wagner and Puccini, lighter works by Balfe, Donizetti, Offenbach and Johann Strauss, some novelties, among which were operas by Holst, Ethel Smyth and Charles Villiers Stanford, and an unusual attempt at staging an oratorio, Mendelssohn's Elijah.In November 1937, Baylis died of a heart attack. Her three companies continued under the direction of her appointed successors: Tyrone Guthrie at the Old Vic, in overall charge of both theatres, with de Valois running the ballet, and Carey and two colleagues running the opera. In the Second World War, the government requisitioned Sadler's Wells as a refuge for those made homeless by air-raids. Guthrie decided to keep the opera going as a small touring ensemble of 20 performers. Between 1942 and the war's end in 1945, the company toured continuously, visiting 87 venues. Joan Cross led and managed the company, and also sang leading soprano roles in its productions when needed. The size of the company was increased to 50, and then to 80. By 1945, its members included singers from a new generation such as Peter Pears and Owen Brannigan, and the conductor Reginald Goodall. 
Question: What is the first name of the person who decided to keep the opera going as a small touring ensemble of 20 performer?

SOLUTION: Tyrone.

PROBLEM: Passage: Lennon first met Yoko Ono on 9 November 1966 at the Indica Gallery in London, where Ono was preparing her conceptual art exhibit. They were introduced by gallery owner John Dunbar. Lennon was intrigued by Ono's "Hammer A Nail": patrons hammered a nail into a wooden board, creating the art piece. Although the exhibition had not yet begun, Lennon wanted to hammer a nail into the clean board, but Ono stopped him. Dunbar asked her, "Don't you know who this is? He's a millionaire! He might buy it." Ono had supposedly not heard of the Beatles, but relented on condition that Lennon pay her five shillings, to which Lennon replied, "I'll give you an imaginary five shillings and hammer an imaginary nail in." Ono subsequently related that Lennon had taken a bite out of the apple on display in her work Apple, much to her fury.Ono began to telephone and visit Lennon at his home. When Cynthia asked him for an explanation, Lennon explained that Ono was only trying to obtain money for her "avant-garde bullshit". While his wife was on holiday in Greece in May 1968, Lennon invited Ono to visit. They spent the night recording what would become the Two Virgins album, after which, he said, they "made love at dawn". When Lennon's wife returned home she found Ono wearing her bathrobe and drinking tea with Lennon who simply said, "Oh, hi." Ono became pregnant in 1968 and miscarried a male child on 21 November 1968, a few weeks after Lennon's divorce from Cynthia was granted.Two years before the Beatles disbanded, Lennon and Ono began public protests against the Vietnam War. They were married in Gibraltar on 20 March 1969, and spent their honeymoon at the Hilton Amsterdam, campaigning with a week-long Bed-In for Peace. They planned another Bed-In in the United States but were denied entry, so they held one instead at the Queen Elizabeth Hotel in Montreal, where they recorded "Give Peace a Chance". They often combined advocacy with performance art, as in their "Bagism", first introduced during a Vienna press conference. Lennon detailed this period in the Beatles song "The Ballad of John and Yoko". Lennon changed his name by deed poll on 22 April 1969, adding "Ono" as a middle name. The brief ceremony took place on the roof of the Apple Corps building, where the Beatles had performed their rooftop concert three months earlier. Although he used the name John Ono Lennon thereafter, official documents referred to him as John Winston Ono Lennon, since he was not permitted to revoke a name given at birth. The couple settled at Tittenhurst Park at Sunninghill in Berkshire. After Ono was injured in a car accident, Lennon arranged for a king-size bed to be brought to the recording studio as he worked on the Beatles' last album, Abbey Road.Ono and Lennon moved to New York, to a flat on Bank Street, Greenwich Village. Looking for somewhere with better security, they relocated in 1973 to the more secure Dakota overlooking Central Park at 1 West 72nd Street. 
Question: What is the first name of Lennon's wife who was on holiday in Greece in May 1968, when he invited Ono to visit?

SOLUTION:
Cynthia.
