Example Input: Question: Which of the two Chicago Bulls player who were teammates on Detroit Pistons and won back-to-back titles had a longer tenure with the Pistons? Passage:The 199596 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 201516 Golden State Warriors, who finished 739. 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.

Example Input: Question: Who is the manufacturer of the suture that its breakdown can be hastened because of bacteria? Passage: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 EhlersDanlos 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.
