" Step 1: Justin Beiber was born on March 1, 1994\nStep 2: The NFL season ends with the Super Bowl in January/February\nStep 3: Therefore, the Super Bowl that occurred closest to Justin Beiber's birth would be Super Bowl XXIX in 1995\nStep 4: The San Francisco 49ers won Super Bowl XXIX in 1995\n\nTherefore, the answer is the San Francisco 49ers won the Super Bowl in the year Justin Beiber was born."
