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 Royal College of Music commissioned an official portrait of the composer from Sir Gerald Kelly (1952) which hangs in the college. The Manchester Art Gallery has a bronze sculpture of Vaughan Williams by Epstein (1952) and the National Portrait Gallery (NPG) has drawings by Joyce Finzi (1947) and Juliet Pannett (1957 and 1958); versions of a bronze head of the composer by David McFall (1956) are in the NPG and at the entrance to the Music reading room of the British Library. There is a statue of Vaughan Williams in Dorking, and a bust in Chelsea Embankment Gardens, near his old house in Cheyne Walk.In 1994 a group of enthusiasts founded the Ralph Vaughan Williams Society, with the composer's widow as its president and Roy Douglas and Michael Kennedy as vice presidents. The society, a registered charity, has sponsored and encouraged performances of the composer's works including complete symphony cycles and a Vaughan Williams opera festival. The society has promoted premieres of neglected works, and has its own record label, Albion Records.Composers of the generation after Vaughan Williams reacted against his style, which became unfashionable in influential musical circles in the 1960s; diatonic and melodic music such as his was neglected in favour of atonal and other modernist compositions. In the 21st century this neglect has been reversed. In the fiftieth anniversary year of his death two contrasting documentary films were released: Tony Palmer's O Thou Transcendent: The Life of Vaughan Williams and John Bridcut's The Passions of Vaughan Williams. British audiences were prompted to reappraise the composer. The popularity of his most accessible works, particularly the Tallis Fantasia and The Lark Ascending increased, but a wide public also became aware of what a reviewer of Bridcut's film called "a genius driven by emotion". Among the 21st-century musicians who have acknowledged Vaughan Williams's influence on their development are John Adams, PJ Harvey, Sir Peter Maxwell Davies, Anthony Payne, Wayne Shorter, Neil Tennant and Mark-Anthony Turnage.The Clements Park development, located in Warley, Brentwood, Essex, has roads taking their names after the composer and his works, the most obvious being the main road "Vaughan Williams Way" which runs through the development. Vaughan Williams lectured in Brentwood on folk music, and collected 140 songs from villages in the region.
