Extract the answer to the question from the following context. Question: Spring and Winter are two examples of what that include two others? Context: The NFL Network ceased airing Arena Football League games partway through the 2012 season as a result of ongoing labor problems within the league. Briefly, the games were broadcast on a tape delay to prevent the embarrassment that would result should the players stage a work stoppage immediately prior to a scheduled broadcast. (In at least once incidence this actually happened, resulting in a non-competitive game being played with replacement players, and further such incidents were threatened.) Once the labor issues were resolved, the NFL Network resumed the practice of broadcasting a live Friday night game. NFL Network dropped the league at the end of the 2012 season.

Q: Extract the answer to the question from the following context. Question: How did a university research charter schools? Context: The K-12 and higher education reform programs of the Gates Foundation have been criticized by some education professionals, parents, and researchers because they have driven the conversation on education reform to such an extent that they may marginalize researchers who do not support Gates' predetermined policy preferences. Several Gates-backed policies such as small schools, charter schools, and increasing class sizes have been expensive and disruptive, but some studies indicate they have not improved educational outcomes and may have caused harm. Peer reviewed scientific studies at Stanford find that Charter Schools do not systematically improve student performance
A: studies

Question: Extract the answer to the question from the following context. Question: How was the plane captured? Context: On May 1, 1960, a U.S. one-man U-2 spy plane was reportedly shot down at high altitude over Soviet Union airspace. The flight was made to gain photo intelligence before the scheduled opening of an EastWest summit conference, which had been scheduled in Paris, 15 days later. Captain Francis Gary Powers had bailed out of his aircraft and was captured after parachuting down onto Russian soil. Four days after Powers disappeared, the Eisenhower Administration had NASA issue a very detailed press release noting that an aircraft had "gone missing" north of Turkey. It speculated that the pilot might have fallen unconscious while the autopilot was still engaged, and falsely claimed that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties."
Answer: shot down

[Q]: Extract the answer to the question from the following context. Question: What is the main point of the passage? Context: Mathematicians often strive for a complete classification (or list) of a mathematical notion. In the context of finite groups, this aim leads to difficult mathematics. According to Lagrange's theorem, finite groups of order p, a prime number, are necessarily cyclic (abelian) groups Zp. Groups of order p2 can also be shown to be abelian, a statement which does not generalize to order p3, as the non-abelian group D4 of order 8 = 23 above shows. Computer algebra systems can be used to list small groups, but there is no classification of all finite groups.q["] An intermediate step is the classification of finite simple groups.r["] A nontrivial group is called simple if its only normal subgroups are the trivial group and the group itself.s["] The JordanHolder theorem exhibits finite simple groups as the building blocks for all finite groups. Listing all finite simple groups was a major achievement in contemporary group theory. 1998 Fields Medal winner Richard Borcherds succeeded in proving the monstrous moonshine conjectures, a surprising and deep relation between the largest finite simple sporadic groupthe "monster group"and certain modular functions, a piece of classical complex analysis, and string theory, a theory supposed to unify the description of many physical phenomena.

input: Please answer the following: Extract the answer to the question from the following context. Question: What type of event is held to celebrate the Queen's Birthday? Context: There is a variety of annual events, beginning with the relatively new New Year's Day Parade, fireworks display at the London Eye, the world's second largest street party, the Notting Hill Carnival is held during the late August Bank Holiday each year. Traditional parades include November's Lord Mayor's Show, a centuries-old event celebrating the annual appointment of a new Lord Mayor of the City of London with a procession along the streets of the City, and June's Trooping the Colour, a formal military pageant performed by regiments of the Commonwealth and British armies to celebrate the Queen's Official Birthday.

output: formal military pageant

Extract the answer to the question from the following context. Question: Which time period happened first, the end of the Carboniferous or the early Cambrian? Context: Since annelids are soft-bodied, their fossils are rare. Polychaetes' fossil record consists mainly of the jaws that some species had and the mineralized tubes that some secreted. Some Ediacaran fossils such as Dickinsonia in some ways resemble polychaetes, but the similarities are too vague for these fossils to be classified with confidence. The small shelly fossil Cloudina, from 549 to 542 million years ago, has been classified by some authors as an annelid, but by others as a cnidarian (i.e. in the phylum to which jellyfish and sea anemones belong). Until 2008 the earliest fossils widely accepted as annelids were the polychaetes Canadia and Burgessochaeta, both from Canada's Burgess Shale, formed about 505 million years ago in the early Cambrian. Myoscolex, found in Australia and a little older than the Burgess Shale, was possibly an annelid. However, it lacks some typical annelid features and has features which are not usually found in annelids and some of which are associated with other phyla. Then Simon Conway Morris and John Peel reported Phragmochaeta from Sirius Passet, about 518 million years old, and concluded that it was the oldest annelid known to date. There has been vigorous debate about whether the Burgess Shale fossil Wiwaxia was a mollusc or an annelid. Polychaetes diversified in the early Ordovician, about 488 to 474 million years ago. It is not until the early Ordovician that the first annelid jaws are found, thus the crown-group cannot have appeared before this date and probably appeared somewhat later. By the end of the Carboniferous, about 299 million years ago, fossils of most of the modern mobile polychaete groups had appeared. Many fossil tubes look like those made by modern sessile polychaetes , but the first tubes clearly produced by polychaetes date from the Jurassic, less than 199 million years ago.
