Question: How many separate organizations are there in the organization that presented Elimination Chamber?

<P0-S0>  All members of the National Guard of the United States are also members of the militia of the United States as defined by  /246 § 246  . <P0-S1> The National Guard of the United States, part of the reserve components of the United States Armed Forces, is a reserve military force, composed of National Guard military members or units of each state and the territories of Guam, of the Virgin Islands, and of Puerto Rico, as well as of the District of Columbia, for a total of 54 separate organizations. <P0-S2>  National Guard units are under the dual control of the state and the federal government. <SEP> <P1-S0> Elimination Chamber is a professional wrestling pay-per-view (PPV) event, produced by WWE, a professional wrestling promotion based in Connecticut. <P1-S1>  The event was created in 2010, with its inaugural event taking place on February 21, 2010, replacing No Way Out. <P1-S2>  Elimination Chamber is a pay-per-view (PPV) event consisting of a main event and undercard that features championship matches and other various matches. <P1-S3>  The concept of the show was that the two main event matches were contested inside the Elimination Chamber; one of these matches typically featured the WWE Championship being defended, while the other was usually contested for the World Heavyweight Championship (the two titles were unified in December 2013). <P1-S4>  The first Elimination Chamber event took place on February 21, 2010 and aired live on PPV. <P1-S5>  The event's name was selected after WWE allowed fans to provide input via a survey on their official website and was chosen over Heavy Metal, Battle Chamber, Chamber of Conflict, and the original No Way Out name. <P1-S6>  Since its origin, each event has been held in an indoor arena, with all five taking place in the United States. <P1-S7>  In 2015, the event was replaced by Fastlane in the February pay-per-view slot. <P1-S8>  However, the 2015 event was later announced to be streamed exclusively on the WWE Network in the United States on May 31 and was also available on PPV elsewhere. <P1-S9>  WWE also confirmed that the newly vacant WWE Intercontinental Championship was being decided inside the Elimination Chamber. <P1-S10>  The event did not occur in 2016, but returned in 2017 as a SmackDown branded event. <SEP> <P2-S0> The Elimination Chamber is a professional wrestling elimination-based match and held in the WWE promotion. <P2-S1>  The match was created by Triple H and was introduced by Eric Bischoff in November 2002. <P2-S2>  It features a large chain-linked circular steel structure, which encloses the ring. <P2-S3>  The chamber's floor is platformed over the ringside area which elevates it to ring level. <P2-S4>  Within the chamber are four inner enclosures outside each ring corner. <P2-S5>  While similar in profile and nature to WWE's original large scale steel-structured match, Hell in a Cell, the Elimination Chamber match is strictly a six participant match, wherein two participants begin the match in the ring as the remaining four are held within each inner enclosure and are released into the match at five-minute intervals. <P2-S6>  The objective is to eliminate each opponent from the match via pinfall or submission. <P2-S7>  The winner is the last remaining participant after all others have been eliminated. <P2-S8>  As in the Hell in a Cell match, disqualifications do not apply. <P2-S9>  The original structure was 16 ft high, 36 ft in diameter, weighed over 10 ST , and comprised 2 mi and 6 ST of chain. <P2-S10>  There have been twenty Elimination Chamber matches in WWE since the concept's inception in November 2002. <SEP> <P3-S0> Elimination Chamber (2011) (also known as No Escape (2011) in Germany) was a professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE) and presented by the National Guard, which took place on February 20, 2011 at the Oracle Arena in Oakland, California.
