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.

Q: Passage: The musical and philosophical ideas behind the opera had begun in Tippett's mind several years earlier. The story, which he wrote himself, charts the fortunes of two contrasting couples in a manner which has brought comparisons with Mozart's The Magic Flute. The strain of composition, combined with his continuing responsibilities at Morley and his BBC work, affected Tippett's health and slowed progress. Following the death in 1949 of Morley's principal, Eva Hubback, Tippett's personal commitment to the college waned. His now-regular BBC fees had made him less dependent on his Morley salary, and he resigned his college post in 1951. His farewell took the form of three concerts which he conducted at the new Royal Festival Hall, in which the programmes included A Child of Our Time, the British première of Carl Orff's Carmina Burana, and Thomas Tallis's rarely performed 40-part motet Spem in alium.In 1951 Tippett moved from Limpsfield to a large, dilapidated house, Tidebrook Manor in Wadhurst, Sussex. As The Midsummer Marriage neared completion he wrote a song cycle for tenor and piano, The Heart's Assurance. This work, a long-delayed tribute to Francesca Allinson (who had committed suicide in 1945), was performed by Britten and Pears at the Wigmore Hall on 7 May 1951. The Midsummer Marriage was finished in 1952, after which Tippett arranged some of the music as a concert suite, the Ritual Dances, performed in Basel, Switzerland, in April 1953. The opera itself was staged at Covent Garden on 27 January 1955. The lavish production, with costumes and stage designs by Barbara Hepworth and choreography by John Cranko, perplexed the opera-going public and divided critical opinion. According to Bowen, most "were simply unprepared for a work that departed so far from the methods of Puccini and Verdi". Tippett's libretto was variously described as "one of the worst in the 350-year history of opera" and "a complex network of verbal symbolism", and the music as "intoxicating beauty" with "passages of superbly conceived orchestral writing". A year after the première, the critic A.E.F. Dickinson concluded that "in spite of notable gaps in continuity and distracting infelicities of language, [there is] strong evidence that the composer has found the right music for his ends".Much of the music Tippett composed following the opera's completion reflected its lyrical style. Among these works was the Fantasia Concertante on a Theme of Corelli (1953) for string orchestra, written to commemorate the 300th anniversary of the composer Arcangelo Corelli's  birth. The Fantasia would eventually become one of Tippett's most popular works, though The Times's critic lamented the "excessive complexity of the contrapuntal writing ... there was so much going on that the perplexed ear knew not where to turn or fasten itself". Such comments helped to foster a view that Tippett was a "difficult" composer, or even that his music was amateurish and poorly prepared. These perceptions were strengthened by controversies around several of his works in the late 1950s. The Piano Concerto (1955) was declared unplayable by its scheduled soloist, Julius Katchen, who had to be replaced before the première by Louis Kentner. The Dennis Brain Wind Ensemble, for whom Tippett had written the Sonata for Four Horns (1955), complained that the work was in too high a key and required it to be transposed down. When the Second Symphony was premièred by the BBC Symphony Orchestra under Boult, in a live broadcast from the Royal Festival Hall on 5 February 1958, the work broke down after a few minutes and had to be restarted by the apologetic conductor: "Entirely my mistake, ladies and gentlemen". The BBC's Controller of Music defended the orchestra in The Times, writing that it "is equal to all reasonable demands", a wording that implied the fault was the composer's.

A: What three things affected Tippett's health?

Q: Passage: When the ship passed Cape Adare, the direction of drift changed to north-westerly. On 10 August Stenhouse estimated that they were 45 nautical miles (83 km) north-east of the Cape, and that their daily drift was averaging just over 20 nautical miles (37 km). A few days later Stenhouse recorded that the ship was "backing and filling", meaning that it was drifting back and forth without making progress. "However, we cannot grumble and must be patient", he wrote, adding that from the crow's nest a distinct impression of open water could be seen. With the possibility that the edge of the pack was nearby, work on the construction of a jury rudder began. This first involved the removal of the wreckage of the smashed rudder, a task largely carried out by Engineer Donnelly. The jury rudder was constructed from makeshift materials, and by 26 August was ready for use as soon as Aurora cleared the ice. It would then be lowered over the stern and operated manually, "like a huge oar".
On 25 August Hooke began picking up occasional radio signals being exchanged between Macquarie Island and New Zealand. By the end of August open leads were beginning to appear, and sometimes it was possible to discern a sea-swell under the ship. Severe weather returned in September, when a hurricane-force wind destroyed the wireless aerial and temporarily halted Hooke's efforts. On 22 September, when Aurora was in sight of the uninhabited Balleny Islands, Stenhouse estimated that they had travelled over 700 nautical miles (1,300 km) from Cape Evans, in what he called a "wonderful drift". He added that regular observations and records of the nature and direction of the ice had been maintained throughout: "It [the drift] has not been in vain, and [...] knowledge of the set and drift of the pack will be a valuable addition to the sum of human knowledge".Aurora's circumstances changed little during the following months. Stenhouse worked hard to maintain morale, keeping the crew working whenever possible and organising leisure activities, including games of football and cricket on the ice. On 21 November Aurora crossed the Antarctic Circle, and it was at last evident that the ice around the ship was beginning to melt: "...one good hefty blizzard would cause a general break up", wrote Stenhouse. Christmas approached with the ice still holding firm; Stenhouse allowed the crew to prepare a feast, but noted in his journal: "I wish to God the blasted festivities were over [...] we are hogging in to the best while the poor beggars at Cape Evans have little or nothing!" A few days later the New Year was celebrated with an improvised band leading choruses of "Rule, Britannia" and "God Save the King".

A: What is the name of the ship whose direction of drift changed northwesterly on passing Cape Adare?

Q: Passage: After the 1903 winter had passed, Scott prepared for the second main journey of the expedition: an ascent of the western mountains and exploration of the interior of Victoria Land. Armitage's reconnaissance party of the previous year had pioneered a route up to altitude 8,900 feet (2,700 m) before returning, but Scott wished to march west from this point, if possible to the location of the South Magnetic Pole. After a false start due to faulty sledges, a party including Scott, Lashly and Edgar Evans set out from Discovery on 26 October 1903.
Ascending a large glacier, which they named after the party's geologist Ferrar, they reached a height of 7,000 feet (2,100 m) before being held in camp for a week by blizzards. This prevented them from reaching the glacier summit until 13 November. They then marched on beyond Armitage's furthest point, discovered the Polar Plateau and became the first party to travel on it. After the return of geological and supporting parties, Scott, Evans and Lashly continued westward across the featureless plain for another eight days, covering a distance of about 150  miles to reach their most westerly point on 30 November. Having lost their navigational tables in a gale during the glacier ascent, they did not know exactly where they were, and had no landmarks to help them fix a position. The return journey to the Ferrar Glacier was undertaken in conditions which limited them to no more than a mile an hour, with supplies running low and dependent on Scott's rule of thumb navigation. On the descent of the glacier Scott and Evans survived a potentially fatal fall into a crevasse, before the discovery of a snow-free area or dry valley, a rare Antarctic phenomenon. Lashly described the dry valley as "a splendid place for growing spuds". The party reached Discovery on 24 December, after a round trip of seven hundred miles covered in 59 days. Their daily average of over 14 miles on this man-hauling journey was significantly better than that achieved with dogs on the previous season's southern journey, a fact which further strengthened Scott's prejudices against dogs. Polar historian David Crane calls the western journey "one of the great journeys of polar history".Several other journeys were completed during Scott's absence. Royds and Bernacchi travelled for 31 days on the Barrier in a SE direction, observing its uniformly flat character and making further magnetic readings. Another party had explored the Koettlitz Glacier to the south-west, and Wilson had travelled to Cape Crozier to observe the emperor penguin colony at close quarters.

A:
What are the last names of the people who reached a height of 7,000 feet (2,100 m) before being held in camp for a week by blizzards?
