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 input: 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.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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.
Q: Passage: Back in Paris with two years of his grant remaining, Bizet was temporarily secure financially and could ignore for the moment the difficulties that other young composers faced in the city. The two state-subsidised opera houses, the Opéra and the Opéra-Comique, each presented traditional repertoires that tended to stifle and frustrate new homegrown talent; only eight of the 54 Prix de Rome laureates between 1830 and 1860 had had works staged at the Opéra. Although French composers were better represented at the Opéra-Comique, the style and character of productions had remained largely unchanged since the 1830s. A number of smaller theatres catered for operetta, a field in which Offenbach was then paramount, while the Théâtre Italien specialised in second-rate Italian opera. The best prospect for aspirant opera composers was the Théâtre Lyrique company which, despite repeated financial crises, operated intermittently in various premises under its resourceful manager Léon Carvalho. This company had staged the first performances of Gounod's Faust and his Roméo et Juliette, and of a shortened version of Berlioz's Les Troyens.On 13 March 1861, Bizet attended the Paris premiere of Wagner's opera Tannhäuser, a performance greeted by audience riots that were stage-managed by the influential Jockey-Club de Paris. Despite this distraction, Bizet revised his opinions of Wagner's music, which he had previously dismissed as merely eccentric. He now declared Wagner "above and beyond all living composers". Thereafter, accusations of "Wagnerism" were often laid against Bizet, throughout his compositional career.As a pianist, Bizet had showed considerable skill from his earliest years. A contemporary asserted that he could have assured a future on the concert platform, but chose to conceal his talent "as though it were a vice". In May 1861 Bizet gave a rare demonstration of his virtuoso skills when, at a dinner party at which Liszt was present, he astonished everyone by playing on sight, flawlessly, one of the maestro's most difficult pieces. Liszt commented: "I thought there were only two men able to surmount the difficulties ... there are three, and ... the youngest is perhaps the boldest and most brilliant.".
A:
What is the name of the maestro that was present while the pianist that showed considerable skill from his early years demonstrated his virtuoso skills?
