In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Igor Stravinsky was the son of Fyodor Stravinsky, the principal bass singer at the Imperial Opera, St Petersburg, and Anna, nee Kholodovskaya, a competent amateur singer and pianist from an old-established Russian family. Fyodor's association with many of the leading figures in Russian music, including Rimsky-Korsakov, Borodin and Mussorgsky, meant that Igor grew up in an intensely musical home. In 1901 Stravinsky began to study law at Saint Petersburg University while taking private lessons in harmony and counterpoint. Stravinsky worked under the guidance of Rimsky-Korsakov, having impressed him with some of his early compositional efforts. By the time of his mentor's death in 1908 Stravinsky had produced several works, among them a Piano Sonata in F minor (190304), a Symphony in E major (1907), which he catalogued as "Opus 1", and a short orchestral piece, Feu d'artifice ("Fireworks", composed in 1908).In 1909 Feu d'artifice was performed at a concert in St. Petersburg. Among those in the audience was the impresario Sergei Diaghilev, who at that time was planning to introduce Russian music and art to western audiences. Like Stravinsky, Diaghilev had initially studied law, but had gravitated via journalism into the theatrical world. In 1907 he began his theatrical career by presenting five concerts in Paris; in the following year he introduced Mussorgsky's opera Boris Godunov. In 1909, still in Paris, he launched the Ballets Russes, initially with Borodin's Polovtsian Dances from Prince Igor and Rimsky-Korsakov's Scheherazade. To present these works Diaghilev recruited the choreographer Michel Fokine, the designer Leon Bakst and the dancer Vaslav Nijinsky. Diaghilev's intention, however, was to produce new works in a distinctively 20th-century style, and he was looking for fresh compositional talent. Having heard Feu d'artifice he approached Stravinsky, initially with a request for help in orchestrating music by Chopin to create the ballet Les Sylphides. Stravinsky worked on the opening "Nocturne" and the closing "Valse Brillante"; his reward was a much bigger commission, to write the music for a new ballet, The Firebird (L'oiseau de feu) for the 1910 season.Stravinsky worked through the winter of 190910, in close association with Fokine who was choreographing The Firebird. During this period Stravinsky made the acquaintance of Nijinsky who, although not dancing in the ballet, was a keen observer of its development. Stravinsky was uncomplimentary when recording his first impressions of the dancer, observing that he seemed immature and gauche for his age (he was 21). On the other hand, Stravinsky found Diaghilev an inspiration, "the very essence of a great personality". The Firebird was premiered on 25 June 1910, with Tamara Karsavina in the main role, and was a great public success. This ensured that the DiaghilevStravinsky collaboration would continue, in the first instance with Petrushka (1911) and then The Rite of Spring.
Question: What is the full name of the person that impressed Rimsky-Korsakov with their early compositional efforts?
Example Output: Igor Stravinsky.

Example Input: Passage: The second half of the 19th century has often been called the Heroic Age of Antarctic Exploration. The inhospitable and dangerous Arctic and Antarctic regions appealed powerfully to the imagination of the age, not as lands with their own ecologies and cultures, but as challenges to be conquered by technological ingenuity and manly daring.
Salomon August Andree shared these enthusiasms, and proposed a plan for letting the wind propel a hydrogen balloon from Svalbard across the Arctic Sea to the Bering Strait, to fetch up in Alaska, Canada, or Russia, and passing near or even right over the North Pole on the way. Andree was an engineer at the patent office in Stockholm, with a passion for ballooning.
He bought his own balloon, the Svea, in 1893 and made nine journeys with it, starting from Gothenburg or Stockholm and traveling a combined distance of 1,500 kilometres (930 mi). In the prevailing westerly winds, the Svea flights had a strong tendency to carry him uncontrollably out to the Baltic Sea and drag his basket perilously along the surface of the water or slam it into one of the many rocky islets in the Stockholm archipelago.
On one occasion he was blown clear across the Baltic to Finland. His longest trip was due east from Gothenburg, across the breadth of Sweden and out over the Baltic to Gotland. Even though he saw a lighthouse and heard breakers off Oland, he remained convinced that he was traveling over land and seeing lakes.During a couple of Svea flights, Andree tested and tried out the drag-rope steering technique which he had developed and wanted to use on his projected North Pole expedition. Drag ropes, which hang from the balloon basket and drag part of their length on the ground, are designed to counteract the tendency of lighter-than-air craft to travel at the same speed as the wind, a situation that makes steering by sails impossible. The friction of the ropes was intended to slow the balloon to the point where the sails would have an effect (beyond that of making the balloon rotate on its axis). Andree reported, and presumably believed, that with drag rope/sails steering he had succeeded in deviating about ten degrees either way from the wind direction.
This notion is rejected by modern balloonists; the Swedish Ballooning Association maintains that Andree's belief that he had deviated from the wind was mistaken, being misled by inexpertise and a surfeit of enthusiasm in an environment of variable winds and poor visibility. Use of drag ropesprone to snapping, falling off, or becoming entangled with each other or the ground, in addition to being ineffectiveis not considered by any modern expert to be a useful steering technique.
Question: What was the name of the technique Andree tried on a couple of Svea flights?
Example Output: drag-rope steering technique.

Example Input: Passage: Productions during the 1980s included the company's first presentations of Pelleas and Melisande (1981), Parsifal (1986) and Billy Budd (1988). 1980s productions that remained in the repertory for many years included Xerxes directed by Hytner, and Rigoletto and The Mikado directed by Jonathan Miller. In 1984 ENO toured the United States; the travelling company, led by Elder, consisted of 360 people; they performed Gloriana, War and Peace, The Turn of the Screw, Rigoletto and Patience. This was the first British company to be invited to appear at the Metropolitan Opera in New York, where Patience received a standing ovation and Miller's production of Rigoletto, depicting the characters as mafiosi, was greeted with a mixture of enthusiasm and booing. In 1990 ENO was the first major foreign opera company to tour the Soviet Union, performing the Miller production of The Turn of the Screw, Pountney's production of Macbeth, and Hytner's much-revived Xerxes.The 'Powerhouse' era ended in 1992, when all three of the triumvirate left at the same time. The new general director was Dennis Marks, formerly head of music programmes at the BBC, and the new music director was Sian Edwards. Pountney's post of director of productions was not filled. Marks, inheriting a large financial deficit from his predecessors, worked to restore the company's finances, concentrating on restoring ticket sales to sustainable levels. A new production by Miller of Der Rosenkavalier was a critical and financial success, as was a staging of Massenet's Don Quixote, described by the critic Hugh Canning as "the kind of old-fashioned theatre magic which the hair-shirted Powerhouse regime despised".Marks was obliged to spend much time and effort in securing the funding for an essential restoration of the Coliseum, a condition on which ENO had acquired the freehold of the theatre in 1992. At the same time the Arts Council was contemplating a cut in the number of opera performances in London, at the expense of ENO, rather than Covent Garden. By increasing ticket sales in successive years, Marks demonstrated that the Arts Council's proposition was unrealistic. After what The Independent described as "a sustained period of criticism and sniping at the ENO by music critics", Edwards resigned as music director at the end of 1995. Paul Daniel became ENO's next music director. In 1997, Marks resigned. No official reason was announced, but one report stated that he and the ENO board had disagreed about his plans to move the company from the Coliseum to a purpose-built new home. Daniel took over the management of the company until a new general director was appointed.Daniel inherited from Marks a company thriving artistically and financially. The 19971998 season played to 75 per cent capacity and made a surplus of 150,000. Daniel led the campaign against yet another proposal to merge Covent Garden and ENO, which was rapidly abandoned. In 1998 Nicholas Payne, director of opera at Covent Garden, was appointed as ENO's general director. Productions in the 1990s included the company's first stagings of Beatrice and Benedict (1990), Wozzeck (1990), Jenufa (1994), A Midsummer Night's Dream (1995), Die Soldaten (1996), and Dialogues of the Carmelites (1999). Co-productions, enabling opera houses to share the costs of joint enterprises, became important in this decade. In 1993 ENO and Welsh National Opera collaborated on productions of Don Pasquale, Ariodante and The Two Widows.
Question: What is the full name of the man that was appointed as general director in 1998 for the company that's 'Powerhouse' era ended in 1992?
Example Output:
Nicholas Payne.
