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.

[EX Q]: Passage: In 1952 the LPO negotiated a five-year contract with Decca Records, which was unusually rewarding for the orchestra, giving it a 10 per cent commission on most sales. On top of this, Boult always contributed his share of the recording fees to the orchestra's funds. In the same year, the LPO survived a crisis when Russell was dismissed as its managing director. He was an avowed member of the Communist party; when the cold war began some influential members of the LPO felt that Russell's private political affiliations compromised the orchestra, and pressed for his dismissal. Boult, as the orchestra's chief conductor, stood up for Russell, but when matters came to a head Boult ceased to protect him. Deprived of that crucial support, Russell was forced out. Kennedy speculates that Boult's change of mind was due to a growing conviction that the orchestra would be "seriously jeopardized financially" if Russell remained in post.  A later writer, Richard Witts, suggests that Boult sacrificed Russell because he believed doing so would enhance the LPO's chance of being appointed resident orchestra at the Royal Festival Hall.In 1953 Boult once again took charge of the orchestral music at a coronation, conducting an ensemble drawn from UK orchestras at the coronation of Elizabeth II. During the proceedings, he conducted the first performances of Bliss's Processional and Walton's march Orb and Sceptre.  In the same year he returned to the Proms after a three-year absence, conducting the LPO. The notices were mixed: The Times found a Brahms symphony "rather colourless, imprecise and uninspiring", but praised Boult and the orchestra's performance of The Planets. In the same year the orchestra celebrated its 21st birthday, giving a series of concerts at the Festival Hall and the Royal Albert Hall in which Boult was joined by guest conductors including Paul Kletzki, Jean Martinon,  Hans Schmidt-Isserstedt, Georg Solti, Walter Susskind and Vaughan Williams.In 1956 Boult and the LPO visited Russia. Boult had not wished to go on the tour because flying hurt his ears, and long land journeys hurt his back. The Soviet authorities threatened to cancel the tour if he did not lead it, and he felt obliged to go. The LPO gave nine concerts in Moscow and four in Leningrad.  Boult's assistant conductors were Anatole Fistoulari and George Hurst. Boult's four Moscow programmes included Vaughan Williams's Fourth and Fifth Symphonies, Holst's The Planets, Walton's Violin Concerto (with Alfredo Campoli as soloist), and Schubert's Great C major Symphony. While in Moscow, Boult and his wife visited the Bolshoi Opera and were guests at the composer Dmitri Shostakovich's 50th birthday party.After the Russian tour, Boult told the LPO that he wished to step down from the principal conductorship. He continued to be the orchestra's main conductor until his successor William Steinberg took up the post in 1959.  After the sudden resignation of Andrzej Panufnik from the City of Birmingham Symphony Orchestra (CBSO), Boult returned as principal conductor of the CBSO for the 1959–60 season. That was his last chief conductorship, though he remained closely associated with the LPO as its president and a guest conductor until his retirement. 
Question: What is the name of the person that flying hurt his ears, and long land journeys hurt his back?
[EX A]: Boult.

[EX Q]: Passage: There is considerable uncertainty about the identities of the Grand Dukes of Lithuania between Traidenis' death in 1282 and Vytenis' assumption of power in 1295. This is in part because the two main sources for Lithuanian history in the 13th century, the Hypatian Codex and the Livonian Rhymed Chronicle, end in the early 1290s. In 1285, one chronicle mentions Daumantas as Grand Duke. He attacked the Bishop of Tver and was severely wounded or even killed in the battle. However, that is the only information about him.
The Gediminid dynasty began its ascent in Lithuania during this time with the emergence of its first leader, Butigeidis. In 1289, leading about 8,000 troops, he attacked Sambia. In 1289 the Teutonic Knights built a castle in present-day Sovetsk (Tilsit) and their raids intensified. Butigeidis was the first to build strong castles along the Neman River. He died in 1290 or 1292, and his brother Butvydas (also known as Pukuveras) inherited the crown. Butvydas was the father of Vytenis and probably of Gediminas. During his short reign Butvydas tried to defend the duchy against the Teutonic Knights; he also attacked Masovia, an ally of the knights. His son, Vytenis, advanced to power in 1295 and ended the period of relative instability. His reign marks the transition from the state's establishment to the point at which it was poised for expansion. 
Question: What is the alias of the person that inherited the crown from Butigeidis?
[EX A]: Pukuveras.

[EX Q]: Passage: Early in March 1676, a Danish fleet of 20 ships under Admiral Niels Juel left Copenhagen. On 29 April it landed troops on Gotland, which soon surrendered. The Swedish fleet was ordered out on 4 May, but experienced adverse winds and was delayed until 19 May. Juel had by then already left Visby, the principal port of Gotland with a garrison force. He headed for Bornholm to join with a small Danish–Dutch squadron in cruising between Scania and the island of Rügen to prevent any Swedish seaborne reinforcement from reaching Pomerania. On 25–26 May the two fleets met each another in the battle of Bornholm. Despite the considerable Swedish advantage in ships, men and guns, they were unable to inflict any losses on the allied force, and lost a fireship and two minor vessels. The battle revealed the lack of coherence and organization within the Swedish ranks, which soured relations between Creutz and his officers.After the failed action, the Swedish fleet anchored off Trelleborg where King Charles was waiting with new orders to recapture Gotland. The fleet was to avoid combat with the allies at least until they reached the northern tip of Öland, where they could fight in friendly waters. When the Swedish fleet left Trelleborg on 30 May they were soon intercepted by the allied fleet, which then began a pursuit. By this time the allies had been reinforced by another small squadron and totaled 42 vessels, with 25 large and medium ships of the line. The reinforcements brought with them a new commander, the Dutch Admiral General Cornelis Tromp, one of the most renowned naval tacticians of his time. The two fleets sailed north and on 1 June passed the northern tip of Öland in a strong gale. The Swedish ships fared poorly in the rough winds, losing masts and spars. The Swedish officers formed a battle line that held together only with great difficulty. They tried to get ahead of Tromp's ships to gain the weather gage by getting between the allies and the shore, and thereby gaining an advantageous tactical position. The Dutch ships of the allied fleet managed to sail close-hauled faster than the rest of the force and slipped between the Swedes and the coast, taking up the crucial weather gage. Later that morning the two fleets closed in on each other and were soon within firing range. 
Question: What is the first name of the person who headed for Bornholm to join with a small Danish–Dutch squadron?
[EX A]:
Niels.
