Instructions: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Input: Question: Youchi Akasaka and Tadashi Nishimura worked at company that is headquartered where? Passage 1:Although Scream of the Shalka continues the narrative of the original 1963–89 programme and the 1996 television film, the show's 2005 revival ignored its events. The series was scripted by veteran Doctor Who writer Paul Cornell, with Richard E. Grant providing the voice for the Ninth Doctor. This performance followed years of rumours that Grant would play the Doctor in a film or new series, and indeed he had appeared as the "Conceited Doctor" in the Comic Relief special Doctor Who and the Curse of Fatal Death in 1999. Grant subsequently went on to appear in the revived television series of Doctor Who as a guest villain in 2012's "The Snowmen" and 2013's "The Bells of Saint John" and "The Name of the Doctor". The Doctor's companion for this adventure, Alison Cheney, was voiced by Sophie Okonedo who a year later would be nominated for an Academy Award for her performance in Hotel Rwanda. She also appeared in the 2010 series of Doctor Who, as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens". Derek Jacobi reprised his role as the Master in 2007's "Utopia". David Tennant appeared in a cameo role as the Caretaker, later being cast as the Tenth Doctor in 2005.
 Passage 2:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.
 Passage 3:Primarily a midfielder, Jüllich began his career with Waldhof Mannheim, where he played for two seasons in the Regionalliga before joining Bayern in July 2010. He made his 3. Liga debut in the opening match of the 2010–11 season, a 1–0 defeat against SV Babelsberg. He has played for Bayern's first-team in pre-season friendlies in 2010, most notably the Franz Beckenbauer farewell match against Real Madrid, where he played as a stand-in for Philipp Lahm at right back, and earned praise for his performance up against Cristiano Ronaldo. He was named in Bayern's squad for the 2010–11 UEFA Champions League, where he was given the number 34, and was named on the substitutes' bench for a Bundesliga match against Hannover 96 in October 2010. After two years with Bayern's reserves, he joined 1. FC Saarbrücken in summer 2012, where he spent a season before being released in 2013. He signed for SG Sonnenhof Großaspach four months later.
