[Q]: Given the following context: Nixon in China is an opera in three acts by John Adams, with a libretto by Alice Goodman. Adams' first opera, it was inspired by U.S. President Richard Nixon's 1972 visit to China. The work premiered at the Houston Grand Opera on October 22, 1987, in a production by Peter Sellars with choreography by Mark Morris. When Sellars approached Adams with the idea for the opera in 1983, Adams was initially reluctant, but eventually decided that the work could be a study in how myths come to be, and accepted the project. Goodman's libretto was the result of considerable research into Nixon's visit, though she disregarded most sources published after the 1972 trip. To create the sounds he sought, Adams augmented the orchestra with a large saxophone section, additional percussion, and electronic synthesizer. Although sometimes described as minimalist, the score displays a variety of musical styles, embracing minimalism after the manner of Philip Glass alongside passages echoing 19th-century composers such as Wagner and Johann Strauss. With these ingredients, Adams mixes Stravinskian 20th-century neoclassicism, jazz references, and big band sounds reminiscent of Nixon's youth in the 1930s. The combination of these elements varies frequently, to reflect changes in the onstage action. Following the 1987 premiere, the opera received mixed reviews; some critics dismissed the work, predicting it would soon vanish. However, it has been presented on many occasions since, in both Europe and North America, and has been recorded twice. In 2011, the opera received its Metropolitan Opera debut, a production based on the original sets, and in the same year was given an abstract production in Toronto by the Canadian Opera Company. Recent critical opinion has tended to recognize the work as a significant and lasting contribution to American opera. answer the following question: What has been recorded twice?

input: Please answer the following: Given the following context: The Five was among the myriad of subjects Tchaikovsky discussed with his benefactress, Nadezhda von Meck. By January 1878, when he wrote to Mrs. von Meck about its members, he had drifted far from their musical world and ideals. In addition, The Five's finest days had long passed. Despite considerable effort in writing operas and songs, Cui had become better known as a critic than as a composer, and even his critical efforts competed for time with his career as an army engineer and expert in the science of fortification. Balakirev had withdrawn completely from the musical scene, Mussorgsky was sinking ever deeper into alcoholism, and Borodin's creative activities increasingly took a back seat to his official duties as a professor of chemistry. Only Rimsky-Korsakov actively pursued a full-time musical career, and he was under increasing fire from his fellow nationalists for much the same reason as Tchaikovsky had been. Like Tchaikovsky, Rimsky-Korsakov had found that, for his own artistic growth to continue unabated, he had to study and master Western classical forms and techniques. Borodin called it "apostasy", adding, "Many are grieved at present by the fact that Korsakov has turned back, has thrown himself into a study of musical antiquity. I do not bemoan it. It is understandable...." Mussorgsky was harsher: "[T]he mighty kuchka had degenerated into soulless traitors."Tchaikovsky's analysis of each of The Five was unsparing. While at least some of his observations may seem distorted and prejudiced, he also mentions some details which ring clear and true. His diagnosis of Rimsky-Korsakov's creative crisis is very accurate. He also calls Mussorgsky the most gifted musically of the Five, though Tchaikovsky could not appreciate the forms Mussorgsky's originality took. Nonetheless, he badly underestimates Borodin's technique and gives Balakirev far less than his full dueall the more telling in light of Balakirev's help in conceiving and shaping Romeo and Juliet.Tchaikovsky wrote to Nadezhda von Meck that all... answer the following question: What is the name of the person whose diagnosis of Rimsky-Korsakov's creative crisis is very accurate?
++++++++++
output: Tchaikovsky

Problem: Given the following context: The estate was requisitioned by the War Ministry from 1940 to 1945 as a local command, training, and ordnance centre. Little remains at the estate from World War II, except the hole created by a bomb dropped by the Luftwaffe. It was enlarged and is now used for swimming and canoeing. After the purchase of the original site in 1919, the purchase of Gilwellbury and adjoining land in 1945 is probably the next most important in Gilwell Park's Scouting history because it allowed The Scout Association to close the original road and fully utilize Branchet Field. It was originally used for small retreats and conferences but is now used as staff accommodation. The Ministry of Education assisted in the purchase.The Gilwell Farmhouse is believed to date from the early 18th century, making it the oldest original building at Gilwell Park. It is composed of two buildings that were joined together. There is a brick well head on the farm that is known as the Gil Well. A field adjoining the boundaries of Gilwell Park, known as Bill Oddie Field, affords dramatic views of the London skyline over Pole Hill, Chingford. The field was so-named after employees of The Scout Association spotted TV ornithologist Bill Oddie recording a programme about circling birds of prey on the field in 2006. After the war, the Boy Scout Association bought adjoining land to increase the estate and protect it from rapidly approaching new developments. These areas are called The Quick, New Field, and Hilly Field. An additional purchase and a donation from South Africa in the early 1950s brought the estate to its present size. This began an era of expanding camping facilities for Scouts which lasted until the early 1960s. Training and sleeping facilities were added through the early 1970s. The Boy Scout Association was renamed The Scout Association in 1967. During the 1970s, two key and popular facilities were built: the Dorothy Hughes Pack Holiday Centre for Cub Scouts and the Colquhoun International Centre for training Scouters, originally called The... answer the following question: What are the names of the areas that ere bought after the war to increase the estate of the Boy Scout Association?

A:
The Quick
