Input: Boston
Boston has teams in the four major North American professional sports leagues plus Major League Soccer, and has won 36 championships in these leagues, As of 2014[update]. It is one of six cities (along with Chicago, Detroit, Los Angeles, New York and Philadelphia) to have won championships in all four major sports. It has been suggested that Boston is the new "TitleTown, USA", as the city's professional sports teams have won nine championships since 2001: Patriots (2001, 2003, 2004, and 2014), Red Sox (2004, 2007, and 2013), Celtics (2008), and Bruins (2011). This love of sports has made Boston the United States Olympic Committee's choice to bid to hold the 2024 Summer Olympic Games, but the city cited financial concerns when it withdrew its bid on July 27, 2015.

How many major North American sports leagues are there?
Output: four

Input: Planck constant
In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.

What method was was used to obtain the measurement?
Output: watt-balance measurement

Input: On the Origin of Species
There were serious scientific objections to the process of natural selection as the key mechanism of evolution, including Karl von Nageli's insistence that a trivial characteristic with no adaptive advantage could not be developed by selection. Darwin conceded that these could be linked to adaptive characteristics. His estimate that the age of the Earth allowed gradual evolution was disputed by William Thomson (later awarded the title Lord Kelvin), who calculated that it had cooled in less than 100 million years. Darwin accepted blending inheritance, but Fleeming Jenkin calculated that as it mixed traits, natural selection could not accumulate useful traits. Darwin tried to meet these objections in the 5th edition. Mivart supported directed evolution, and compiled scientific and religious objections to natural selection. In response, Darwin made considerable changes to the sixth edition. The problems of the age of the Earth and heredity were only resolved in the 20th century.

What were William Thomson's reasons for disputing Darwin's estimate?
Output: calculated that it had cooled in less than 100 million years

Input: Myanmar
Myanmar's armed forces are known as the Tatmadaw, which numbers 488,000. The Tatmadaw comprises the Army, the Navy, and the Air Force. The country ranked twelfth in the world for its number of active troops in service. The military is very influential in Myanmar, with all top cabinet and ministry posts usually held by military officials. Official figures for military spending are not available. Estimates vary widely because of uncertain exchange rates, but Myanmar's military forces' expenses are high. Myanmar imports most of its weapons from Russia, Ukraine, China and India.

How large is the military of Burma ?
Output:
numbers 488,000
