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.

Question: What war were the boats like Kennedy was on used in? Passage:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."

Question: Did Shane Rimmer continue to act after Bishop finished his last TV project? Passage:Bishop continued to act on film, TV and radio, usually in British and other European productions, and was a frequent guest at science fiction conventions. Bishop and fellow Anderson actor Shane Rimmer (a Canadian actor who often worked in the UK) often joked about how often their professional paths crossed and termed themselves "Rent-a-yank". They appeared together as NASA operatives in the opening of You Only Live Twice and as United States Navy sailors in The Bedford Incident, as well as the 1983 film of the Harold Robbins novel The Lonely Lady. In 1989, Bishop was reunited with Rimmer and another Anderson actor, Matt Zimmerman, in the BBC Radio 4 adaptation of Sir Arthur Conan Doyle's A Study In Scarlet. Bishop and Rimmer also toured together in theatre shows including Death of a Salesman in the 1990s and also appeared in the BBC drama-documentary Hiroshima (2005), one of Bishop's last TV projects.
