Question: How old was Mstislav Rostropovich the year Matthews won the Ian Whyte Award? Passage 1:Shortly before 2012 LegCo elections, Johnny Mak, the party's sole District Councillor, and his group Democratic Alliance broke apart from the People Power, as Johnny Mak wanted to lead a candidate list in the New Territories West. The party gained more than ten percent of the vote in the geographical constituency and won three seats. Wong Yuk-man and Albert Chan were re-elected to the Legislative Council, with Ray Chan newly elected in the New Territories East as the first openly gay legislator in Hong Kong history. Chairman Christopher Lau Gar-hung failed to win a seat with Stephen Shiu in Hong Kong Island. Wong Yuk-man's protege Wong Yeung-tat also failed to win a seat where he contested against the LSD chairman Andrew To, who Wong Yuk-man split with a year ago. The People Power fiercely attacked the Democratic Party candidates during the campaign and called for blank vote in the District Council (Second) constituency created under the 2010 constitutional reform package and not voting for the Democratic Party and the Association for Democracy and People's Livelihood (ADPL). Wong Yeung-tat left and formed the Civic Passion.
 Passage 2:In 1975 his orchestral Fourth Sonata (written 1974–75) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (1977–81), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortège was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American première in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American première of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.
 Passage 3:The 2008–09 season is FC Vaslui's 7th season of its existence, and its 4th in a row, in Liga I. Because it finished 7th, FC Vaslui played on UEFA Intertoto Cup in the third round. FC Vaslui passed by Neftchi Baku, and it qualified for the 3rd preliminary round of UEFA Cup. In the play-off, it was eliminated by Slavia Prague, because of the away goal rule, being the only Romanian team, who was eliminated, without losing in UEFA Cup that season. In the championship, they started perfectly, after a 1-0 win against FC Steaua Bucureşti and a 3-1 win against arch rivals Poli Iaşi. But because of the injuries, the team results began to be poor. After a 1-1 draw with Gaz Metan Mediaş, Viorel Hizo was dismissed, and Viorel Moldovan was named the new coach. The team entered in the winter break, on the 9th place. In the winter break, Adrian Porumboiu spent over 3 million €, for new signings, being the only Romanian team, who weren't affected by the Global Economical Crisis. With Moldovan, the team reached the semi-finals of Romanian Cup, but after a 1-4 loss against Gloria Buzău, Moldovan was also sacked, and as a manager, was named the assistant Dulca. With Dulca as a coach, FC Vaslui resurrected, and saved its season, in the last 2 games, after a 1-0 win against FC Rapid Bucureşti, and also a 1-0 win against Universitatea Craiova in front of 25.000 fans on Ion Oblemencu. The team finished 5th, and qualified in the 3rd round of UEFA Europa League.
