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.
