Instructions: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Input: Question: In what city did Black become a literary agent? Passage 1:Sommer was born in Mouzon, in the Ardennes département of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.
 Passage 2: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.
 Passage 3:A primary cause of wound dehiscence is sub-acute infection, resulting from inadequate or imperfect aseptic technique. Coated suture, such as Vicryl, generally breaks down at a rate predicted to correspond with tissue healing, but is hastened in the presence of bacteria. In the absence of other known metabolic factors which inhibit healing and may have contributed to suture dehiscence, sub-acute infection should be suspected and the protocol of obtaining wound cultures followed by treatment with the appropriate antibiotics should be undertaken. Dehiscence can also be caused by inadequate undermining (cutting the skin away from the underlying tissues) of the wound during surgery, excessive tension on the wound edges caused by lifting or straining, or the wound being located on a highly mobile or high tension area such as the back, shoulders or legs. Individuals with Ehlers–Danlos syndrome also commonly experience wound dehiscence. Risk factors can include any of the above as well as obesity, smoking, previous scarring, surgical error, cancer, chronic use of corticosteroids and increased abdominal pressure. A very common cause is also use and especially overuse of nicotine in any form. Smoking should therefore be stopped a certain time before any surgery.
