Given the task definition, example input & output, solve the new input case.
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.
Example: 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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: In 1924, Monteux began a ten-year association with the Concertgebouw Orchestra of Amsterdam, serving as "first conductor" ("eerste dirigent") alongside Willem Mengelberg, its long-serving chief conductor. The two musicians liked and respected one another, despite the difference in their approach to music-making: Monteux was scrupulous in his adherence to a composer's score and straightforward in his performances, while Mengelberg was well known for his virtuoso, sometimes wilful, interpretations and his cavalier attitude to the score ("Ve vill make some changements", as an English player quoted him). Their preferred repertoire overlapped in some of the classics, but Mengelberg had his own favourites from Bach's St. Matthew Passion to Mahler symphonies, and was happy to leave Debussy and Stravinsky to Monteux. Where their choices coincided, as in Beethoven, Brahms and Richard Strauss, Mengelberg was generous in giving Monteux at least his fair share of them.While in Amsterdam Monteux conducted a number of operas, including Pelleas et Melisande (its Dutch premiere), Carmen, Les Contes d'Hoffmann, a Lully and Ravel double bill of Acis et Galatee and L'Heure espagnole, Gluck's Iphigenie en Tauride (also brought to the Paris Opera) and Verdi's Falstaff. Toscanini had been invited to conduct the last of these, but he told the promoters that Monteux was his dearest colleague and the best conductor for Falstaff.During the first eight years of his association with the Concertgebouw, Monteux conducted between fifty and sixty concerts each season. In his final two years with the orchestra other conductors, notably the rising young Dutchman Eduard van Beinum, were allocated concerts that would previously have been given to Monteux, who amicably withdrew from his position in Amsterdam in 1934. He returned many times as a guest conductor.
Output:
What is the full name of the rising conductor that was given concerts usually given to the man who conducted between fifty and sixty concerts each season?
