Input: Consider Input: 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

Input: Consider Input: Question: Which team was ranked the highest at the 2009 Pacific Nations Cup? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).

Input: Consider Input: Question: How long was the painting a feature of the collection before being acquired by Catherine II of Russia? Passage:By 1627 the painting belonged to William Herbert, 3rd Earl of Pembroke (1580-1630), and was at Wilton House in Wiltshire. Either the 3rd or 4th earl presented it to King Charles I of England. After the English Civil War it was sold in one of the sales of the Royal Collection at Somerset House in London on 19 December 1651. Soon after it was in France. The painting was later a highlight of the Pierre Crozat collection which was acquired through Diderot's mediation by Catherine II of Russia in 1772. For a century and a half, the panel hung in the Imperial Hermitage Museum. It was one of the most popular paintings in the entire collection of the Tsars. In March 1931 it was part of the Soviet sale of Hermitage paintings, and bought by Andrew Mellon, as part of his founding donation to the National Gallery of Art in Washington D.C. This and other foundational artworks, including paintings by Jan van Eyck, Sandro Botticelli, and Titian, helped place the National Gallery among the most significant collections of Renaissance art.
