Problem: Background: Muddy Waters' birthplace and date are not conclusively known. He stated that he was born in Rolling Fork, Mississippi, in 1915, but it is believed to be more likely that he was born in Jug's Corner, in neighboring Issaquena County, in 1913. Recent research has uncovered documentation showing that in the 1930s and 1940s, before his rise to fame, the year of his birth was reported as 1913 on his marriage license, recording notes, and musicians' union card. A 1955 interview in the Chicago Defender is the earliest in which he stated 1915 as the year of his birth, and he continued to say this in interviews from that point onward.
Context: In August 1941, Alan Lomax went to Stovall, Mississippi, on behalf of the Library of Congress to record various country blues musicians. "He brought his stuff down and recorded me right in my house," Muddy recalled for Rolling Stone magazine, "and when he played back the first song I sounded just like anybody's records. Man, you don't know how I felt that Saturday afternoon when I heard that voice and it was my own voice. Later on he sent me two copies of the pressing and a check for twenty bucks, and I carried that record up to the corner and put it on the jukebox. Just played it and played it and said, 'I can do it, I can do it.'" Lomax came back in July 1942 to record him again. Both sessions were eventually released by Testament Records as Down on Stovall's Plantation. The complete recordings were reissued by Chess Records on CD as Muddy Waters: The Complete Plantation Recordings. The Historic 1941-42 Library of Congress Field Recordings in 1993 and remastered in 1997.  In 1943, Muddy Waters headed to Chicago with the hope of becoming a full-time professional musician. He lived with a relative for a short period while driving a truck and working in a factory by day and performing at night. Big Bill Broonzy, then one of the leading bluesmen in Chicago, had Muddy Waters open his shows in the rowdy clubs where Broonzy played. This gave Muddy Waters the opportunity to play in front of a large audience. In 1944, he bought his first electric guitar and then formed his first electric combo. He felt obliged to electrify his sound in Chicago because, he said, "When I went into the clubs, the first thing I wanted was an amplifier. Couldn't nobody hear you with an acoustic." His sound reflected the optimism of postwar African Americans. Willie Dixon said that "There was quite a few people around singing the blues but most of them was singing all sad blues. Muddy was giving his blues a little pep."  Three years later, in 1946, he recorded some songs for Mayo Williams at Columbia Records, with an old-fashioned combo consisting of clarinet, saxophone and piano; they were released a year later with Ivan Ballen's Philadelphia-based 20th Century label, billed as James "Sweet Lucy" Carter and his Orchestra - Muddy Waters' name was not mentioned on the label. Later that year, he began recording for Aristocrat Records, a newly formed label run by the brothers Leonard and Phil Chess. In 1947, he played guitar with Sunnyland Slim on piano on the cuts "Gypsy Woman" and "Little Anna Mae". These were also shelved, but in 1948, "I Can't Be Satisfied" and "I Feel Like Going Home" became hits, and his popularity in clubs began to take off. Soon after, Aristocrat changed its name to Chess Records. Muddy Waters's signature tune "Rollin' Stone" also became a hit that year.
Question: What did he do in 1943?
Answer: In 1943, Muddy Waters headed to Chicago with the hope of becoming a full-time professional musician.

Problem: Background: Lewis Robert "Hack" Wilson (April 26, 1900 - November 23, 1948) was an American Major League Baseball player who played 12 seasons for the New York Giants, Chicago Cubs, Brooklyn Dodgers and Philadelphia Phillies. Despite his diminutive stature, he was one of the most accomplished power hitters in the game during the late 1920s and early 1930s. His 1930 season with the Cubs is widely considered one of the most memorable individual single-season hitting performances in baseball history. Highlights included 56 home runs, the National League record for 68 years; and 191 runs batted in, a mark yet to be surpassed. "
Context: Lewis Robert Wilson was born April 26, 1900, in the Pennsylvania steel mill town of Ellwood City, north of Pittsburgh. His mother, Jennie Kaughn, 16, was an unemployed drifter from Philadelphia; his father, Robert Wilson, 24, was a steel worker. His parents never married; both were heavy drinkers, and in 1907 his mother died of appendicitis at the age of 24.  In 1916 Lewis left school to take a job at a locomotive factory, swinging a sledge hammer for four dollars a week. Although only five feet six inches tall, he weighed 195 pounds with an 18-inch neck, and feet that fit into size-five-and-one-half shoes. Sportswriter Shirley Povich later observed that he was "built along the lines of a beer keg, and was not wholly unfamiliar with its contents." While his unusual physique was considered an oddity at the time, his large head, tiny feet, short legs and broad, flat face are now recognized as hallmarks of the Fetal Alcohol Syndrome.  In 1921 Wilson moved to Martinsburg, West Virginia, to join the Martinsburg Mountaineers of the Class "D" Blue Ridge League. After breaking his leg while sliding into home plate during his first professional game, he was moved from the catcher's position to the outfield. In 1922 he met Virginia Riddleburger, a 34-year-old office clerk; they married the following year. In 1923, playing for the "B" division Portsmouth Truckers, he led the Virginia League in hitting with a .388 batting average. Late in the season, New York Giants manager John McGraw purchased his contract from Portsmouth for $10,500.
