You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input: Passage: Boult, unlike many of his contemporaries, preferred the traditional orchestral layout, with first violins on the conductor's left and the seconds on the right. Of the practice of grouping all the violins together on the left, he wrote, "The new seating is, I admit, easier for the conductor and the second violins, but I firmly maintain that the second violins themselves sound far better on the right. ... When the new fashion reached us from America somewhere about 1908 it was adopted by some conductors, but Richter, Weingartner, Walter, Toscanini and many others kept what I feel is the right balance."This care for balance was an important feature of Boult's music-making. Orchestral players across decades commented on his insistence that every important part should be heard without difficulty. His BBC principal violist wrote in 1938, "If a woodwind player has to complain that he has already been blowing 'fit to burst' there is trouble for somebody." The trombonist Ray Premru wrote forty years later, "One of the old school, like Boult, is so refreshing because he will reduce the dynamic level – 'No, no, pianissimo, strings, let the soloist through, less from everyone else.' That is the old idea of balance."As an educator, Boult influenced several generations of musicians, beginning with his conducting class at the Royal College of Music, London, which he ran from 1919 to 1930. As no such classes had been held before in Britain, Boult "created its curriculum from out of his own experience. ... From that first small class has come all the later formal training for conductors throughout Britain." In the 1930s Boult ran a series of "conferences for conductors" at his country house near Guildford, sometimes helped by Vaughan Williams who lived a few miles away. From 1962 to 1966 he again taught at the Royal College of Music. In later life, he made time for young conductors who sought his counsel.  Among those who studied with or were influenced by Boult were Colin Davis, James Loughran, Richard Hickox and Vernon Handley. The last was not only a pupil of Boult, but acted as his musical assistant on many occasions.
Solution:
What was the last year Boult taught at the Royal College of Music?
