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.

Question: How old was the Liberal Unionist MP when he died? Passage:Morton first stood for Parliament at the 1885 general election, when he contested Hythe, and was unsuccessful again in Christchurch at the 1886 election. He won a seat three years later, when he was elected at a by-election in October 1889 as the Member of Parliament (MP) for Peterborough, after the death of the Liberal Unionist MP John Wentworth-FitzWilliam, becoming the 81st new MP since the general election in 1886. His victory was unexpected, and when the result was declared he said that he hoped his victory would be seen as a gesture of conciliation Ireland. He was re-elected in 1892, and raised in Parliament the issue of the appointment of Justices of the Peace (magistrates) in April 1893. In November that year, 280 Gladstonian MPs met the Lord Chancellor, Lord Herschell, in the House of Lords to discuss the system. Morton led the response to the Lord Chancellor's explanation and defence of the existing system of appointment, and denounced the reliance on advice from Lord Lieutenants who were entirely dependent on what Morton called "class cliques". He was also a member of a Select Committee set up to examine the accommodation provided for members and officials of the House of Commons. Great Western Railway
