[Q]: 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.

[Q]: Question: Who did the U.S. president whose personal representative  helped to negotiate a settlement which resulted in the election of General Fuad Chehab run against when he was elected? Passage:Following shakedown training near Guantanamo Bay, Cuba, during the summer, Van Voorhis reported at Newport, Rhode Island, for duty with Escort Squadron 14 (CortRon 14). The destroyer escort conducted operations along the east coast of North America until May 1958 when she sailed across the Atlantic for a cruise with the 6th Fleet. While operating with other ships of the 6th Fleet near Crete, she was ordered to the eastern end of the Mediterranean in mid-July to patrol off the Levantine coast. She supported the Marines who landed in Lebanon in response to President Camille Chamoun's request for help during a crisis precipitated by Arab nationalist factions in reaction to his administration's pro-Western policies and its adherence to the Eisenhower Doctrine. President Dwight D. Eisenhower's personal representative Robert D. Murphy helped the factions to negotiate a settlement which resulted in the election of General Fuad Chehab to the presidency on 31 July. President Chamoun's refusal to yield office before the expiration of his term kept the country in turmoil until late September. However, political conditions in Lebanon remained highly volatile, so American forces remained there until after General Chehab took office in September. During this period, Van Voorhis alternated normal 6th Fleet operations with patrols off Lebanon. Late in September, the warship departed the Mediterranean and returned to Newport early in October.
