Input: Read this: As the Laws were formulated in England, and were initially administered solely by the four British football associations within IFAB, the standard dimensions of a football pitch were originally expressed in imperial units. The Laws now express dimensions with approximate metric equivalents (followed by traditional units in brackets), though use of imperial units remains popular in English-speaking countries with a relatively recent history of metrication (or only partial metrication), such as Britain.
Question: What kind of countries are imperial units not considered popular?

Output: unanswerable

Input: Read this: Southampton is home to Southampton Football Clubnicknamed "The Saints"who play in the Premier League at St Mary's Stadium, having relocated in 2001 from their 103-year-old former stadium, "The Dell". They reached the top flight of English football (First Division) for the first time in 1966, staying there for eight years. They lifted the FA Cup with a shock victory over Manchester United in 1976, returned to the top flight two years later, and stayed there for 27 years (becoming founder members of the Premier League in 1992) before they were relegated in 2005. The club was promoted back to the Premier League in 2012 following a brief spell in the third-tier and severe financial difficulties. In 2015, "The Saints" finished 7th in the Premier League, their highest league finish in 30 years, after a remarkable season under new manager Ronald Koeman. Their highest league position came in 1984 when they were runners-up in the old First Division. They were also runners-up in the 1979 Football League Cup final and 2003 FA Cup final. Notable former managers include Ted Bates, Lawrie McMenemy, Chris Nicholl, Ian Branfoot and Gordon Strachan. There is a strong rivalry between Portsmouth F.C. ("South Coast derby") which is located only about 30 km (19 mi) away.
Question: What stadium has been home to The Saints since 2001?

Output: St Mary's Stadium

Input: Read this: Santa Monica College is a junior college originally founded in 1929. Many SMC graduates transfer to the University of California system. It occupies 35 acres (14 hectares) and enrolls 30,000 students annually. The Frederick S. Pardee RAND Graduate School, associated with the RAND Corporation, is the U.S.'s largest producer of public policy PhDs. The Art Institute of California Los Angeles is also located in Santa Monica near the Santa Monica Airport. Universities and colleges within a 22-mile (35 km) radius from Santa Monica include Santa Monica College, Antioch University Los Angeles, Loyola Marymount University, Mount St. Mary's College, Pepperdine University, California State University, Northridge, California State University, Los Angeles, UCLA, USC, West Los Angeles College, California Institute of Technology (Caltech), Occidental College (Oxy), Los Angeles City College, Los Angeles Southwest College, Los Angeles Valley College, and Emperor's College of Traditional Oriental Medicine.
Question: How many students attend the Emperor's College of Traditional Oriental Medicine?

Output: unanswerable

Input: Read this: Thermal conductivity gauges rely on the fact that the ability of a gas to conduct heat decreases with pressure. In this type of gauge, a wire filament is heated by running current through it. A thermocouple or Resistance Temperature Detector (RTD) can then be used to measure the temperature of the filament. This temperature is dependent on the rate at which the filament loses heat to the surrounding gas, and therefore on the thermal conductivity. A common variant is the Pirani gauge which uses a single platinum filament as both the heated element and RTD. These gauges are accurate from 10 torr to 103 torr, but they are sensitive to the chemical composition of the gases being measured.
Question: Pressure is sensitive to the heated element of what?

Output:
unanswerable
