question:
Question: How long was Bill Hewitt the director? Passage:The Billy Bishop Regional Airport in the nearby Municipality of Meaford was named after him. His modest gravesite can be visited in the city's Greenwood Cemetery by those willing to take the time to locate the stone. His boyhood home is now a museum dedicated to his life and to Canada's aviation history. The town was also the home of National Hockey League (NHL) Hall of Fame goaltender Harry Lumley and the artist Tom Thomson (buried in the nearby village of Leith). Surgeon Norman Bethune, an avowed communist and pioneer of public medicine who gained notoriety in his innovative medical work with the Chinese army during the Second Sino-Japanese War, is an alumnus of the Owen Sound Collegiate and Vocational Institute. Legendary hockey broadcaster Bill Hewitt was once sports director of the local AM radio station, CFOS. Thomas William Holmes, another Victoria Cross winner, was also from Owen Sound, and the city's armoury bears his name.

question:
Question: Which of the companies involved with the three-dimensional integrated circuit was founded first? Passage: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.

question:
Question: Did the Houston loss in the AAC Tournament happen before their first round defeat in the NIT? Passage:On April 3, 2014, Houston hired Kelvin Sampson as the new Cougars head coach. Sampson had just become eligible to be a college coach again after receiving a five-year show cause penalty in 2008 for sanctions against him during his time as Indiana head coach. In 2014–15, Houston struggled again, finishing with a 13–19 record and 4–14 in the AAC. The 2015–16 team led a resurgence, finishing 22–10, 12–6, but lost in the AAC Tournament and in the first round of the NIT. In 2017–18, the Cougars compiled a 27–8 record, reaching the finals of the AAC Tournament and winning a game in the NCAA Tournament for the first time since 1984. In 2018–19, the Cougars' success continued as they set a program record for wins with a 33–4 mark. They were AAC regular-season champions but fell in the finals of the conference tournament. They proceeded to the NCAA Tournament, where they reached the Sweet Sixteen for the first time in 35 years.
