Question: Which of the party leaders during the 2001 election had the longest political career? Passage 1:Elections to the Australian Capital Territory Legislative Assembly were held on Saturday, 20 October 2001. The incumbent Liberal Party, led by Gary Humphries, was challenged by the Labor Party, led by Jon Stanhope. Candidates were elected to fill three multi-member electorates using a single transferable vote method, known as the Hare-Clark system. The result was another hung parliament. However Labor, with the largest representation in the 17-member unicameral Assembly, formed Government with the support of the ACT Greens and Democrats. Stanhope was elected Chief Minister at the first sitting of the fifth Assembly on 12 November 2001. The election was conducted by the ACT Electoral Commission and was the first time in Australia's history that an electronic voting and counting system was used for some, but not all, polling places.
Passage 2: was the 2nd Matsudaira daimyo of Matsumoto Domain and 7th hereditary chieftain of the Toda-Matsudaira clan. His courtesy title was Tamba-no-kami. Mitsuo was the fifth son of Matsudaira Mitsuhiro and was born at Yodo Castle. In 1732, he was posthumous adopted as heir by his elder brother, Matsudaira Mitsuchika and was received in formal audience by Shogun Tokugawa Yoshimune. In 1735, the authority to issue travel permits to women passing through official checkpoints at the Usui Pass and Fukushima-juku on then Nakasendo highway was restored to Matsumoto Domain. In 1743, the shogunate abolished its jin'ya at Shiojiri and placed the 159 tenryo villages with a kokudaka of 53,290 koku under the administration of Matsumoto Domain, although subsequently (in 1788), Naka-no-jo jin'ya was established to administer 13,000 koku of this territory. His wife was a daughter of Satake Yoshimune of Kubota Domain. He died at the clan's Gofukubashi residence in Edo in 1756 at the age of 41.
Passage 3:Lisney made a single appearance in first-class cricket for the Surrey Club against the Marylebone Cricket Club (MCC) at Lord's in 1853. In a match which the MCC won by 66 runs, Lisney took five wickets in the MCC first-innings, finishing with figures of 5/33 from twenty overs. In the Surrey Club first-innings, Lisney was last man out when he was run out for 3 runs. He then proceeded to take three wickets in the MCC second-innings, but his exact figures in this innings are unknown due to an incomplete scorecard. In the Surrey Club second-innings, he was again last man out, this time dismissed for a duck by Thomas Nixon. He later stood as an umpire in the return fixture between the two sides in July 1853 at The Oval, before standing in a match between Surrey and Kent later in the season.
