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: In September 1970 Britten asked Myfanwy Piper, who had adapted the two Henry James stories for him, to turn another prose story into a libretto. This was Thomas Mann's novella Death in Venice, a subject he had been considering for some time. At an early stage in composition Britten was told by his doctors that a heart operation was essential if he was to live for more than two years. He was determined to finish the opera and worked urgently to complete it before going into hospital for surgery. His long-term colleague Colin Graham wrote:
Perhaps of all his works, this one went deepest into Britten's own soul: there are extraordinary cross-currents of affinity between himself, his own state of health and mind, Thomas Mann, Aschenbach (Mann's dying protagonist), and Peter Pears, who must have had to tear himself in three in order to reconstitute himself as the principal character.
After the completion of the opera Britten went into the National Heart Hospital and was operated on in May 1973 to replace a failing heart valve. The replacement was successful, but he suffered a slight stroke, affecting his right hand. This brought his career as a performer to an end. While in hospital Britten became friendly with a senior nursing sister, Rita Thomson; she moved to Aldeburgh in 1974 and looked after him until his death.Britten's last works include the Suite on English Folk Tunes "A Time There Was" (1974); the Third String Quartet (1975), which drew on material from Death in Venice; and the dramatic cantata Phaedra (1975), written for Janet Baker.In June 1976, the last year of his life, Britten accepted a life peerage – the first composer so honoured – becoming Baron Britten, of Aldeburgh in the County of Suffolk. After the 1976 Aldeburgh Festival, Britten and Pears travelled to Norway, where Britten began writing Praise We Great Men, for voices and orchestra based on a poem by Edith Sitwell. He returned to Aldeburgh in August, and wrote Welcome Ode for children's choir and orchestra. In November, Britten realised that he could no longer compose. On his 63rd birthday, 22 November, at his request Rita Thomson organised a champagne party and invited his friends and his sisters Barbara and Beth, to say their goodbyes to the dying composer. When Rostropovich made his farewell visit a few days later, Britten gave him what he had written of Praise We Great Men.
Britten died of congestive heart failure on 4 December 1976. His funeral service was held at Aldeburgh Parish Church three days later, and he was buried in its churchyard, with a gravestone carved by Reynolds Stone. The authorities at Westminster Abbey had offered burial there, but Britten had made it clear that he wished his grave to be side by side with that, in due course, of Pears. A memorial service was held at the Abbey on 10 March 1977, at which the congregation was headed by Queen Elizabeth The Queen Mother.

Answer: Who worked urgently to complete their opera before going into hospital for surgery?


Question: Passage: Curiously, it appears that the Greeks did not "breed" their slaves, at least during the Classical Era, though the proportion of houseborn slaves appears to have been rather large in Ptolemaic Egypt and in manumission inscriptions at Delphi. Sometimes the cause of this was natural; mines, for instance, were exclusively a male domain. On the other hand, there were many female domestic slaves. The example of African slaves in the American South on the other hand demonstrates that slave populations can multiply.Xenophon advised that male and female slaves should be lodged separately, that "…nor children born and bred by our domestics without our knowledge and consent—no unimportant matter, since, if the act of rearing children tends to make good servants still more loyally disposed, cohabiting but sharpens ingenuity for mischief in the bad." The explanation is perhaps economic; even a skilled slave was cheap, so it may have been cheaper to purchase a slave than to raise one. Additionally, childbirth placed the slave-mother's life at risk, and the baby was not guaranteed to survive to adulthood.Houseborn slaves (oikogeneis) often constituted a privileged class. They were, for example, entrusted to take the children to school; they were "pedagogues" in the first sense of the term. Some of them were the offspring of the master of the house, but in most cities, notably Athens, a child inherited the status of its mother.

Answer: What were entrusted to take children to school?


Question: Passage: The arrival of the Manchester Ship Canal in 1894, and the subsequent development of the Trafford Park industrial estate in the north of the town – the first planned industrial estate in the world – had a substantial effect on Stretford's growth. The population in 1891 was 21,751, but by 1901 it had increased by 40% to 30,436 as people were drawn to the town by the promise of work in the new industries at Trafford Park.During the Second World War Trafford Park was largely turned over to the production of matériel, including the Avro Manchester heavy bomber, and the Rolls-Royce Merlin engines used to power both the Spitfire and the Lancaster. That resulted in Stretford being the target for heavy bombing, particularly during the Manchester Blitz of 1940. On the nights of 22/23 and 23/24 December 1940 alone, 124 incendiaries and 120 high-explosive bombs fell on the town, killing 73 people and injuring many more. Among the buildings damaged or destroyed during the war were Manchester United's Old Trafford football ground, All Saints' Church, St Hilda's Church, and the children's library in King Street. Smoke generators were set up in the north of the town close to Trafford Park in an effort to hide it from enemy aircraft, and 11,900 children were evacuated to safer areas in Lancashire, Cheshire, Derbyshire, and Staffordshire, along with their teachers and supervisors. A memorial to those residents who lost their lives in the bombing was erected in Stretford Cemetery in 1948, over the communal grave of the 17 unidentified people who were killed in the blitz of December 1940.Between 1972 and 1975, what is now a closed B&Q store in Great Stone Road was the 3,000-capacity Hardrock Theatre and Village Discothèque, hosting some of that period's major artists in their prime. Led Zeppelin, David Bowie, Bob Marley, Elton John, Hawkwind, Yes, Chaka Khan, Curved Air and Lou Reed were amongst those who appeared. Tangerine Dream was the last band to perform at the Hardrock, on 19 October 1975. In more recent years, Lancashire Cricket Club's Old Trafford ground, next door, has provided a concert venue for bands such as Oasis, Foo Fighters, The Cure, Radiohead, Coldplay, Arctic Monkeys and Pixies.
