Q: Question: How long had the NBA been in operation when the Chicago Bulls celebrated their 30th season in the league? Passage 1:The Battle of Badr (), fought on Tuesday, 13 March 624 CE (17 Ramadan, 2 AH in the Islamic calendar) in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. All knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. There is little evidence outside of these of the battle. There are no descriptions of the battle prior to the 9th century.
 Passage 2:Gresham was born to William Gresham (1802–1834) and his wife Sarah Davis. William had been elected a Colonel in the militia of Indiana. He was a member of the Whig Party and was elected Sheriff of Harrison County, Indiana. On January 26, 1834, William was fatally stabbed while assisting in the arrest of Levi Sipes, a so-called "desperado". His paternal grandparents were George Gresham (born 1776) and Mary Pennington. George was born in Virginia but later settled in Kentucky. He moved to Indiana in 1809. Mary was the only sister of Dennis Pennington, speaker of the first Indiana Senate. George Gresham was a son of Lawrence Gresham. Lawrence was born in England but moved to the Colony of Virginia in 1759. He initially served as an indentured servant of an uncle. He was released from service upon reaching adulthood. He later served in the Continental Army. He married Sarah O'Neal. Lawrence followed his son to Kentucky and Indiana well into his old age.
 Passage 3:The 1995–96 NBA season was the Bulls' 30th season in the National Basketball Association. During the offseason, the Bulls acquired rebound-specialist Dennis Rodman from the San Antonio Spurs, and signed free agent Randy Brown. Midway through the season, the team signed John Salley, who was released by the expansion Toronto Raptors. Salley won championships with the Detroit Pistons along with Rodman in 1989 and 1990. The 1996 Bulls is regarded to be the greatest Jordan team of the 90s and undoubtably of all time. This saw the Bulls set the record for most wins in an NBA regular season in which they won the championship, finishing with 72 wins and 10 losses. The regular season record was broken by the 2015–16 Golden State Warriors, who finished 73–9. The Warriors(2015-2016) have a connection to the (1995-1996) Bulls team, as Steve Kerr, the current Golden State coach, was a reserve point guard with the Bulls.
