Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs. 
Question: Who believes Fagin's gang make wallets and handkerchiefs?
Solution: Oliver.
Why? In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

New input: Passage: 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. 
Question: What position did the son of the man in service to the Prince-Archbishop get appointed to?
Solution:
court musician.
