In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Question: Who believes Fagin's gang make wallets and handkerchiefs?
Example solution: Oliver.
Example explanation: In the sentence "He believes they make wallets and handkerchiefs", the pronoun "he" refers to name "Oliver".

Problem: Passage: In February 1935, at Bridge's instigation, Britten was invited to a job interview by the BBC's director of music Adrian Boult and his assistant Edward Clark. Britten was not enthusiastic about the prospect of working full-time in the BBC music department and was relieved when what came out of the interview was an invitation to write the score for a documentary film, The King's Stamp, directed by Alberto Cavalcanti for the GPO Film Unit.
Britten became a member of the film unit's small group of regular contributors, another of whom was W. H. Auden. Together they worked on the documentary films Coal Face and Night Mail in 1935. They also collaborated on the song cycle Our Hunting Fathers (1936), radical both in politics and musical treatment, and subsequently other works including Cabaret Songs, On This Island, Paul Bunyan and Hymn to St. Cecilia. Auden was a considerable influence on Britten, encouraging him to widen his aesthetic, intellectual and political horizons, and also to come to terms with his homosexuality. Auden was, as David Matthews puts it, "cheerfully and guiltlessly promiscuous"; Britten, puritanical and conventional by nature, was sexually repressed.In the three years from 1935 to 1937 Britten wrote nearly 40 scores for the theatre, cinema and radio. Among the film music of the late 1930s Matthews singles out Night Mail and Love from a Stranger (1937); from the theatre music he selects for mention The Ascent of F6 (1936), On the Frontier (1938) and Johnson Over Jordan (1939); and of the music for radio, King Arthur (1937) and The Sword in the Stone (1939).In 1937 there were two events of huge importance in Britten's life: his mother died, and he met the tenor Peter Pears. Although Britten was extraordinarily devoted to his mother and was devastated at her death, it also seems to have been something of a liberation for him. Only after that did he begin to engage in emotional relationships with people his own age or younger. Later in the year he got to know Pears while they were both helping to clear out the country cottage of a mutual friend who had died in an air crash. Pears quickly became Britten's musical inspiration and close (though for the moment platonic) friend. Britten's first work for him was composed within weeks of their meeting, a setting of Emily Bronte's poem, "A thousand gleaming fires", for tenor and strings.During 1937 Britten composed a Pacifist March to words by Ronald Duncan for the Peace Pledge Union, of which, as a pacifist, he had become an active member; the work was not a success and was soon withdrawn. The best known of his compositions from this period is probably Variations on a Theme of Frank Bridge for string orchestra, described by Matthews as the first of Britten's works to become a popular classic. It was a success in North America, with performances in Toronto, New York, Boston, Chicago and San Francisco, under conductors including John Barbirolli and Serge Koussevitzky.
Question: What conductors performed Variations on a Theme of Frank Bridge for string orchestra?
Solution: John Barbirolli.
