Q: Question: How many people live on the island that  Christopher Lau Gar-hung failed to win a seat in? 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: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.
 Passage 3:His role during the reign of his father is unknown. He first appears as the protovestiarios (chamberlain) of Constantine VII Porphyrogennetos (r. 913–959), the legitimate emperor of the Macedonian dynasty, but it is unclear whether it was Romanos Lekapenos who appointed him to the post or whether Constantine VII gave it to him after Romanos' downfall. The contemporary Theophanes Continuatus reports that Basil was a loyal and dedicated servant of Constantine VII, and had a close relationship with Constantine's wife, and his own half-sister, Helena Lekapene. Following the deposition of Romanos Lekapenos in December 944, Basil supported Constantine VII when he regained power from Basil's half-brothers Stephen Lekapenos and Constantine Lekapenos in January 945, and was rewarded with senior titles and offices: in his seals and dedicatory inscriptions he is called a basilikos, patrikios, "paradynasteuon of the Senate" (likely a distortion indicating the combined titles of paradynasteuon and protos, "first", of the Senate), as well as megas baioulos (grand preceptor) of Constantine's son and heir, the future Romanos II (r. 959–963). In ca. 947/8 he was raised further from protovestiarios to parakoimomenos (head chamberlain), in succession to Theophanes.
