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.

Question: Passage: The Ming dynasty () was the ruling dynasty of China then known as the Great Ming Empire for 276 years (13681644) following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last imperial dynasty in China ruled by ethnic Han Chinese. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne collectively called the Southern Ming survived until 1683.
The Hongwu Emperor (ruled 136898) attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and unrelated magnates, enfeoffing his many sons throughout China and attempting to guide these princes through the Huang-Ming Zuxun, a set of published dynastic instructions. This failed when his teenage successor, the Jianwen Emperor, attempted to curtail his uncles' power, prompting the Jingnan Campaign, an uprising that placed the Prince of Yan upon the throne as the Yongle Emperor in 1402. The Yongle Emperor established Yan as a secondary capital and renamed it Beijing, constructed the Forbidden City, and restored the Grand Canal and the primacy of the imperial examinations in official appointments. He rewarded his eunuch supporters and employed them as a counterweight against the Confucian scholar-bureaucrats. One, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia and the eastern coasts of Africa.
The rise of new emperors and new factions diminished such extravagances; the capture of the Zhengtong Emperor during the 1449 Tumu Crisis ended them completely. The imperial navy was allowed to fall into disrepair while forced labor constructed the Liaodong palisade and connected and fortified the Great Wall of China into its modern form. Wide-ranging censuses of the entire empire were conducted decennially, but the desire to avoid labor and taxes and the difficulty of storing and reviewing the enormous archives at Nanjing hampered accurate figures. Estimates for the late-Ming population vary from 160 to 200 million, but necessary revenues were squeezed out of smaller and smaller numbers of farmers as more disappeared from the official records or "donated" their lands to tax-exempt eunuchs or temples. Haijin laws intended to protect the coasts from "Japanese" pirates instead turned many into smugglers and pirates themselves.

Answer: What was the title of the person who established Yan as a secondary capital and renamed it Beijing before becoming emperor?

Question: Passage: In June 1911, as part of the celebrations surrounding the coronation of King George V, Elgar was appointed to the Order of Merit, an honour limited to twenty-four holders at any time. The following year, the Elgars moved back to London, to a large house in Netherhall Gardens, Hampstead, designed by Norman Shaw. There Elgar composed his last two large-scale works of the pre-war era, the choral ode, The Music Makers (for the Birmingham Festival, 1912) and the symphonic study Falstaff (for the Leeds Festival, 1913). Both were received politely but without enthusiasm. Even the dedicatee of Falstaff, the conductor Landon Ronald, confessed privately that he could not "make head or tail of the piece," while the musical scholar Percy Scholes wrote of Falstaff that it was a "great work" but, "so far as public appreciation goes, a comparative failure."When World War I broke out, Elgar was horrified at the prospect of the carnage, but his patriotic feelings were nonetheless aroused. He composed "A Song for Soldiers", which he later withdrew. He signed up as a special constable in the local police and later joined the Hampstead Volunteer Reserve of the army. He composed patriotic works, Carillon, a recitation for speaker and orchestra in honour of Belgium, and Polonia, an orchestral piece in honour of Poland. Land of Hope and Glory, already popular, became still more so, and Elgar wished in vain to have new, less nationalistic, words sung to the tune.
By contrast, the remaining work, the Cello Concerto in E minor, had a disastrous premiere, at the opening concert of the London Symphony Orchestra's 191920 season in October 1919. Apart from the Elgar work, which the composer conducted, the rest of the programme was conducted by Albert Coates, who overran his rehearsal time at the expense of Elgar's. Lady Elgar wrote, "that brutal selfish ill-mannered bounder ... that brute Coates went on rehearsing." The critic of The Observer, Ernest Newman, wrote, "There have been rumours about during the week of inadequate rehearsal. Whatever the explanation, the sad fact remains that never, in all probability, has so great an orchestra made so lamentable an exhibition of itself. ... The work itself is lovely stuff, very simple that pregnant simplicity that has come upon Elgar's music in the last couple of years but with a profound wisdom and beauty underlying its simplicity." Elgar attached no blame to his soloist, Felix Salmond, who played for him again later, including at the inaugural concert of the City of Birmingham Orchestra (later City of Birmingham Symphony Orchestra), which Elgar conducted. In contrast with the First Symphony and its hundred performances in just over a year, the Cello Concerto did not have a second performance in London for more than a year.

Answer: What are the exact titles of the two separate works that were both received politely but without enthusiasm?

Question: Passage: On August 16, delegations from other strike committees arrived at the shipyard. Delegates (Bogdan Lis, Andrzej Gwiazda and others) together with shipyard strikers agreed to create an Inter-Enterprise Strike Committee (Miedzyzakadowy Komitet Strajkowy, or MKS). On August 17 a priest, Henryk Jankowski, performed a mass outside the shipyard's gate, at which 21 demands of the MKS were put forward. The list went beyond purely local matters, beginning with a demand for new, independent trade unions and going on to call for a relaxation of the censorship, a right to strike, new rights for the Church, the freeing of political prisoners, and improvements in the national health service.Next day, a delegation of KOR intelligentsia, including Tadeusz Mazowiecki, arrived to offer their assistance with negotiations. A bibua news-sheet, Solidarnosc, produced on the shipyard's printing press with KOR assistance, reached a daily print run of 30,000 copies. Meanwhile, Jacek Kaczmarski's protest song, Mury (Walls), gained popularity with the workers.On August 18, the Szczecin Shipyard joined the strike, under the leadership of Marian Jurczyk. A tidal wave of strikes swept the coast, closing ports and bringing the economy to a halt. With KOR assistance and support from many intellectuals, workers occupying factories, mines and shipyards across Poland joined forces. Within days, over 200 factories and enterprises had joined the strike committee. By August 21, most of Poland was affected by the strikes, from coastal shipyards to the mines of the Upper Silesian Industrial Area (in Upper Silesia, the city of Jastrzebie-Zdroj became center of the strikes, with a separate committee organized there, see Jastrzebie-Zdroj 1980 strikes). More and more new unions were formed, and joined the federation.

Answer:
What were the last name of two of the delegates who agreed to crate an Inter-Enterprise Strike Committee?
