Problem: However, from 1971 to 1975, NBA teams played preseason exhibitions against American Basketball Association teams. In the early days of the NBA, league clubs sometimes challenged the legendary barnstorming Harlem Globetrotters, with mixed success. The NBA has played preseason games in Europe and Asia. In the 2006 and 2007 seasons, the NBA and the primary European club competition, the Euroleague, conducted a preseason tournament featuring two NBA teams and the finalists from that year's Euroleague.[citation needed] In the 1998-99 and 2011-12 seasons, teams were limited to only two preseason games due to lockouts.
How many preseason games were NBA teams limited to in the 2011-12 season?
The answer is the following: two

Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
Members of Craft Masonry are called what?
Freemasons or Masons

Input: Capacitor
For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.

What percentage of voltage reversal will an under damped DC circuit experience?
Output: less than 100%

Input: Article: Tibet retained nominal power over religious and regional political affairs, while the Mongols managed a structural and administrative rule over the region, reinforced by the rare military intervention. This existed as a "diarchic structure" under the Yuan emperor, with power primarily in favor of the Mongols. Mongolian prince Khuden gained temporal power in Tibet in the 1240s and sponsored Sakya Pandita, whose seat became the capital of Tibet. Drogon Chogyal Phagpa, Sakya Pandita's nephew became Imperial Preceptor of Kublai Khan, founder of the Yuan dynasty.

Now answer this question: Who gained temporal power in Tibet in the 1240s?

Output: Mongolian prince Khuden

Article: The term "Sumerian" is the common name given to the ancient non-Semitic inhabitants of Mesopotamia, Sumer, by the Semitic Akkadians. The Sumerians referred to themselves as ug sag gig-ga (cuneiform: ), phonetically /u sa giga/, literally meaning "the black-headed people", and to their land as ki-en-gi(-r) ('place' + 'lords' + 'noble'), meaning "place of the noble lords". The Akkadian word Shumer may represent the geographical name in dialect, but the phonological development leading to the Akkadian term sumeru is uncertain. Hebrew Shinar, Egyptian Sngr, and Hittite Sanhar(a), all referring to southern Mesopotamia, could be western variants of Shumer.

Question: What did the Sumerians refer to themselves as in their language?
Ans: "the black-headed people"

Input: Mexico City
Mexico City is served by the Sistema de Transporte Colectivo, a 225.9 km (140 mi) metro system, which is the largest in Latin America. The first portions were opened in 1969 and it has expanded to 12 lines with 195 stations. The metro is one of the busiest in the world transporting approximately 4.5 million people every day, surpassed only by subway lines in Moscow (7.5 million), Tokyo (5.9 million), and New York City (5.1 million). It is heavily subsidized, and has some of the lowest fares in the world, each trip costing 5.00 pesos from 05:00 am to midnight. Several stations display pre-Columbian artifacts and architecture that were discovered during the metro's construction.[citation needed] However, the metro covers less than half of the total urban area. The Metro stations are also differentiated by the use of icons and glyphs which were proposed for people who could not read. The specific icons were developed based on historical (characters, sites, pre-Hispanic motifs), linguistic, symbolic (glyphs) or location references and has being emulated in further transportations alternatives in the City and in other Mexican cities. Mexico City is the only city in the world to use the icon reference and has become a popular culture trademark for the city.

How large is the metro system of Mexico City?
Output:
225.9 km (140 mi)
