Input: Consider Input: Question: Of the two people who reached the finals on December 13th who has released the most albums? Passage:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.

Input: Consider Input: Question: What is the definition of the Werther effect? Passage:In July 1994, two students of Taipei First Girls' High School committed suicide by charcoal-burning in a hotel in Su'ao, Yilan with a note that didn't state the reason clearly, even though that it was suspected in some mass media that they were a lesbian couple. In November 1998, a middle-aged woman in Hong Kong died by suicide using this method inside her small, sealed bedroom. She had a chemical engineering background. Hong Kong was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local mass media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. By 2001, it had surpassed hanging as the second most-common method of suicide in Hong Kong (second only to jumping), accounting for about 25% of all suicide deaths. The method has since spread to mainland China, Taiwan and Japan.

Input: Consider Input: Question: How many points did Priddis' team score during his second season? Passage:Priddis was raised in Manjimup, a country town in Western Australia's south-west region, but moved to Perth, the state's capital, as a teenager, playing at junior level for Sorrento–Duncraig. He represented Western Australia at both under-16 and under-18 level respectively, in addition to also making his senior debut for in the West Australian Football League (WAFL) as well, playing two games early in the 2003 season. Priddis became a regular in Subiaco's senior side during the 2004 season. He played 21 games, including Subiaco's win over in the Grand Final, en route to ultimately being named the WAFL's Rising Star at the end of the season. At the end of the season, he was offered a well-paid contract in the South Australian National Football League (SANFL), but turned it down on the advice of Subiaco's coach, Peter German. During the 2005 season, Priddis won Subiaco's best and fairest award, the Tom Outridge Medal, as well as also winning the Simpson Medal as Western Australia's best player in the state game against Queensland. He was subsequently selected by West Coast with the 31st pick in the 2006 Rookie Draft, but only after he had already been overlooked in three previous national drafts.
