Example Input: Question: In what city did Black become a literary agent? Passage:Black was head hunted and she became a literary agent at Curtis Brown. She played golf and used her connections to find clients that included Somerset Maugham and Samuel Beckett. She was involved with the noted production of Samuel Beckett's Waiting for Godot in 1956 and holidayed with Maugham in France. She notably told John Osborne to "think again" about his play Look Back in Anger that transformed British theatre. Black was fluent in French and so in love with France that she was sometimes called "Noir". She created translations of plays that were enabled not only be her fluency in French but with her knowledge of theatre after reading so many plays as a literary agent. Her translations included Crime Passionel by Jean Paul Sartre. She also translated his play "Morts sans Sépulture" and was thrilled when the director said that it was perfect. In partnership with Michael Flanders, she translated Stravinsky's Histoire du soldat for the Edinburgh Festival. The work played to capacity audiences in Edinburgh, and again in London at the Royal Festival Hall in 1956 with Flanders as the narrator, Sir Ralph Richardson as the Soldier and Peter Ustinov as the Devil. Their translation has held its place as the standard English version into the 21st century.

Example Input: Question: Which manager of Port Vale FC had the best record during the 1950s? Passage:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.

Example Input: Question: How old was Wendy Cope when she collaborated with Matthews on three poems? Passage:In 1975 his orchestral Fourth Sonata (written 1974–75) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (1977–81), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortège was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American première in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American première of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.
