[Q]: The answer to the question: What is the last name of the person who obtained an extended leave of absence? is inside the article: The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their musically gifted children Maria Anna (Nannerl) and Wolfgang Amadeus from 1763 to 1766. At the start of the tour the children were aged eleven and seven respectively. Their extraordinary skills had been demonstrated during a visit to Vienna in 1762, when they had played before the Empress Maria Theresa at the Imperial Court. Sensing the social and pecuniary opportunities that might accrue from a prolonged trip embracing the capitals and main cultural centres of Europe, Leopold obtained an extended leave of absence from his post as deputy Kapellmeister to the Prince-Archbishopric of Salzburg. Throughout the subsequent tour, the children's Wunderkind status was confirmed as their precocious performances consistently amazed and gratified their audiences. The first stage of the tour's itinerary took the family, via Munich and Frankfurt, to Brussels and then on to Paris where they stayed for five months. They then departed for London, where during a stay of more than a year Wolfgang made the acquaintance of some of the leading musicians of the day, heard much music, and composed his first symphonies. The family then moved on to the Netherlands, where the schedule of performances was interrupted by the illnesses of both children, although Wolfgang continued to compose prolifically. The homeward phase incorporated a second stop in Paris and a trip through Switzerland, before the family's return to Salzburg in November 1766. The material rewards of the tour, though reportedly substantial, did not transform the family's lifestyle, and Leopold continued in the Prince-Archbishop's service. However, the journey enabled the children to experience to the full the cosmopolitan musical world, and gave them an outstanding education. In Wolfgang's case this would continue through further journeys in the following six years, prior to his appointment by the Prince-Archbishop as a court musician., can you guess it ?

input: Please answer the following: The answer to the question: When did the man who was appointed to the Ministry of Justice graduate from his music studies? is inside the article: Tchaikovsky was born in 1840 in Votkinsk, a small town in present-day Udmurtia, formerly the Imperial Russian province of Vyatka. A precocious pupil, he began piano lessons at the age of five, and could read music as adeptly as his teacher within three years. However, his parents' passion for his musical talent soon cooled. In 1850, the family decided to send Tchaikovsky to the Imperial School of Jurisprudence in Saint Petersburg. This establishment mainly served the lesser nobility or gentry, and would prepare him for a career as a civil servant. As the minimum age for acceptance was 12, Tchaikovsky was sent by his family to board at the Imperial School of Jurisprudence's preparatory school in Saint Petersburg, 800 miles (1,300 km) from his family home in Alapayevsk. Once Tchaikovsky came of age for acceptance, he was transferred to the Imperial School of Jurisprudence to begin a seven-year course of studies.Music was not a priority at the School, but Tchaikovsky regularly attended the theater and the opera with other students. He was fond of works by Rossini, Bellini, Verdi and Mozart. Piano manufacturer Franz Becker made occasional visits to the School as a token music teacher. This was the only formal music instruction Tchaikovsky received there. From 1855 the composer's father, Ilya Tchaikovsky, funded private lessons with Rudolph Kundinger, a well-known piano teacher from Nuremberg, and questioned Kundinger about a musical career for his son. Kundinger replied that nothing suggested a potential composer or even a fine performer. Tchaikovsky was told to finish his course and then try for a post in the Ministry of Justice.Tchaikovsky graduated on May 25, 1859 with the rank of titular counselor, a low rung on the civil service ladder. On June 15, he was appointed to the Ministry of Justice in Saint Petersburg. Six months later he became a junior assistant and two months after that, a senior assistant. Tchaikovsky remained there for the rest of his three-year civil service career.In 1861, Tchaikovsky..., can you guess it ?

Problem: The answer to the question: What is the last name of the person whose tenure with the duke made him a wealthy man? is inside the article: Nicolas Rolin was appointed Chancellor of Burgundy by Philip the Good in 1422, a position he held for the next 33 years. His tenure with the duke made him a wealthy man, and he donated a large portion of his fortune for the foundation of the Hotel-Dieu in Beaune. It is not known why he decided to build in Beaune rather than in his birthplace of Autun. He may have chosen Beaune because it lacked a hospital and an outbreak of the plague decimated the population between 1438 and 1440. Furthermore, when in 1435 the Treaty of Arras failed to bring a cessation to the longstanding hostility and animosity between Burgundy and France, the town suffered brutal ravages and famine from ecorcheurs (marauding bands) who roamed the countryside during the late 1430s and early 1440s. The hospice was built after Rolin gained permission from Pope Eugene IV in 1441, and it was eventually consecrated on 31 December 1452. In conjunction, Rolin established the religious order of "Les surs hospitalieres de Beaune". Rolin dedicated the hospice to St Anthony Abbot, who was commonly associated with sickness and healing during the Middle Ages. In the hospice's founding charter, signed in August 1443, Rolin wrote that "disregarding all human concerns and in the interest of my salvation, desiring by a favourable trade to exchange for celestial goods temporal ones, that I might from divine goodness render those goods which are perishable for ones which are eternal ... in gratitude for the goods which the Lord, source of all wealth, has heaped upon me, from now on and for always, I found a hospital." In the late 1450s, only a few years before he died, he added a provision to the hospital charter stipulating that the Mass for the Dead be offered twice daily. Rolin's wife, Guigone de Salins, played a major role in the foundation, as probably did his nephew Jan Rolin. De Salins lived and served at the hospice until her own death in 1470.Documents regarding the artwork's commissioning survive and, unusually for a Netherlandish altarpiece,..., can you guess it ?
