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.

[EX Q]: Passage: Willow has been cut and used on the Levels since mankind moved into the area. Fragments of willow basket were found near the Glastonbury Lake Village, and it was used in the construction of several Iron Age causeways. The willow was harvested using traditional methods of pollarding, where a tree would be cut back to the main stem. New shoots of willow, called "withies", would grow out of the trunk and these would be cut periodically for use.During the 1930s, over 9,000 acres (36 km2) of willow were being grown commercially on the Levels. Largely because of the replacement of baskets by plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 350 acres (1.4 km2) were grown commercially, near the villages of Burrowbridge, Westonzoyland, and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially. For weaving, the species Salix triandra (almond willow, black maul) is grown, while Salix viminalis (common osier) is ideal for handles, bases, and the structural members in furniture and hurdles. Historically willow was used to make salmon traps or "putchers". Products including baskets, eel traps (kypes), lobster pots, and furniture were widely made from willow throughout the area in the recent past. Among the more unusual products still made are passenger baskets for hot air balloons, the frames inside the Bearskins worn by the regiments of the Grenadier Guards, and an increasing number of willow coffins.Another use of willow has been found by the Coate family, who make artists' charcoals in Stoke St Gregory. It has become in 30 years the leading artists' charcoal manufacturer in Europe, producing most of the natural charcoals sold under different art-material brands.The industry is celebrated in the form of the Willow Man (sometimes known as the Angel of the South), a willow sculpture, 40 feet (12.2 m) tall, produced by artist Serena de la Hey in September 2000 that can be seen from the railway and the M5 motorway to the north of Bridgwater. At Stoke St Gregory there is also a Willows and Wetlands Visitor Centre.
[EX A]: What is the name of the family that is the leading artists' charcoal manufacturer in Europe?

[EX Q]: Passage: I was told that I did not learn respect at school. I learned one thing: I learned about self-respect and self-regard for Australia—not about some cultural cringe to a country which decided not to defend the Malayan peninsula, not to worry about Singapore and not to give us our troops back to keep ourselves free from Japanese domination. This was the country that you people wedded yourself to, and even as it walked out on you and joined the Common Market, you were still looking for your MBEs and your knighthoods, and all the rest of the regalia that comes with it.
A fleet was necessary for the defeat of Japan, and eventually a sizeable one, the British Pacific Fleet, did go to the Far East, where it fought alongside the United States Pacific Fleet. The closer relations that developed between the two navies prior to the outbreak of war with Japan, and the alliance that developed from it afterwards, became the most positive and enduring strategic legacy of the Singapore strategy.The Singapore Naval Base suffered little damage in the fighting and became the Imperial Japanese Navy's most important facility outside of the Japanese home islands. The 15-inch guns were sabotaged by the British before the fall of Singapore, and four of them were deemed beyond repair and scrapped by the Japanese. The floating dry dock was scuttled by the British, but raised by the Japanese. It was damaged beyond repair by a raid by Boeing B-29 Superfortresses in February 1945, and ultimately towed out to sea and dumped in 1946. The Royal Navy retook possession of the Singapore base in 1945.
[EX A]: What did the Royal Navy retake possession of in 1945?

[EX Q]: Passage: With the South London  Orchestra temporarily disbanded because of the war, Tippett returned to teaching at Hazelwood. In October 1940 he accepted the post of Director of Music at Morley College, just after its buildings were almost completely destroyed by a bomb. Tippett's challenge was to rebuild the musical life of the college, using temporary premises and whatever resources he could muster. He revived the Morley College Choir and orchestra, and arranged innovative concert programmes that typically mixed early music (Orlando Gibbons, Monteverdi, Dowland), with contemporary works by Stravinsky, Hindemith and Bartók.
He continued the college's established association with the music of Purcell; a performance in November 1941 of Purcell's Ode to St Cecilia, with improvised instruments and rearrangements of voice parts, attracted considerable attention. The music staff at Morley was augmented by the recruitment of refugee musicians from Europe, including Walter Bergmann, Mátyás Seiber, and Walter Goehr who took charge of the college orchestra.A Child of Our Time was finished in 1941 and put aside with no immediate prospects of  performance. Tippett's Fantasia on a Theme of Handel for piano and orchestra was performed at the Wigmore Hall in March 1942, with Sellick again the soloist, and the same venue saw the première of the composer's String Quartet No. 2 a year later. The first recording of Tippett's  music, the Piano Sonata No. 1  played by Sellick, was issued in August 1941. The recording was well received by the critics, Wilfrid Mellers predicting a leading role for the composer in the future of English music. In 1942, Schott Music began to publish Tippett's works, establishing an association that continued until the end of the composer's life.The question of Tippett's liability for war service remained unresolved until mid-1943. In November 1940 he had formalised his pacifism by joining the Peace Pledge Union and applying for registration as a conscientious objector. His case was heard by a tribunal in February 1942, when he was assigned to non-combatant duties. Tippett rejected such work as an unacceptable compromise with his principles and in June 1943, after several further hearings and statements on his behalf from distinguished musical figures,  he was sentenced to three months' imprisonment in HM Prison Wormwood Scrubs. He served two months, and although thereafter he was technically liable to further charges for failing to comply with the terms set by his tribunal, the authorities left him alone.
[EX A]:
What is the last name of the person who had formalised his pacifism by joining the Peace Pledge Union?
