Example Input: Question: Who did Vinny Del Negro play for before he signed with the Spurs? Passage:The 1992–93 NBA season was the Spurs' 17th season in the National Basketball Association, and 26th season as a franchise. During the offseason, Terry Cummings suffered a serious knee injury and only played in the final eight games of the season. With the acquisition of Dale Ellis from the Milwaukee Bucks and signing free agent Vinny Del Negro, plus re-signing Avery Johnson after a brief stint with the Houston Rockets, the Spurs struggled with a 9–11 start to the season as new head coach Jerry Tarkanian was fired. After playing one game under Rex Hughes, the team hired John Lucas II as their new coach. At midseason, they acquired J.R. Reid from the Charlotte Hornets. Under Lucas, the Spurs would play solid basketball posting a 10-game winning streak in January, then winning eight straight in February, finishing second in the Midwest Division with a 49–33 record. David Robinson and Sean Elliott were both selected for the 1993 NBA All-Star Game.

Example Input: Question: In 1958 did the Linguistic Society of America have more total members than the American Philosophical Society? Passage:He was educated in the German Gymnasium, where he learned the classical languages, and trained as an Indo-Europeanist and a historical and comparative linguist in universities in Munich, Zurich, Padua, and Florence. His refugee status compelled these moves (his grandparents were Jewish, and by 1933 Jews were forbidden to attend German universities). In 1939 he escaped to the United States, where he was at first a research assistant at Yale. He taught at the University of Pennsylvania from 1948 until his retirement in 1985. He was a member of the Linguistic Society of America, of which he was elected President in 1958, and a member of the American Philosophical Society for more than 30 years.
