Problem: Please answer a question about the following article about Wood:
In the case of the ring-porous hardwoods there seems to exist a pretty definite relation between the rate of growth of timber and its properties. This may be briefly summed up in the general statement that the more rapid the growth or the wider the rings of growth, the heavier, harder, stronger, and stiffer the wood. This, it must be remembered, applies only to ring-porous woods such as oak, ash, hickory, and others of the same group, and is, of course, subject to some exceptions and limitations.
What is the only kind of wood that will definitely be harder and stronger when it grows faster?
A: ring-porous
Problem: Please answer a question about the following article about Freemasonry:
Widespread segregation in 19th- and early 20th-century North America made it difficult for African-Americans to join Lodges outside of Prince Hall jurisdictions – and impossible for inter-jurisdiction recognition between the parallel U.S. Masonic authorities. By the 1980s, such discrimination was a thing of the past, and today most U.S. Grand Lodges recognise their Prince Hall counterparts, and the authorities of both traditions are working towards full recognition. The United Grand Lodge of England has no problem with recognising Prince Hall Grand Lodges. While celebrating their heritage as lodges of black Americans, Prince Hall is open to all men regardless of race or religion.
Who is the Prince Hall Lodge open to?
A: Prince Hall is open to all men
Problem: Please answer a question about the following article about Detroit:
Beginning with its incorporation in 1802, Detroit has had a total of 74 mayors. Detroit's last mayor from the Republican Party was Louis Miriani, who served from 1957 to 1962. In 1973, the city elected its first black mayor, Coleman Young. Despite development efforts, his combative style during his five terms in office was not well received by many suburban residents. Mayor Dennis Archer, a former Michigan Supreme Court Justice, refocused the city's attention on redevelopment with a plan to permit three casinos downtown. By 2008, three major casino resort hotels established operations in the city.
How many mayors has Detroit had?
A: 74

These absolute desert regions are characterized by their extreme aridity, and some years can pass without any rainfall.
