[Q]: Question: "Nuclear purposes use?" Context: "Energy transformations in the universe over time are characterized by various kinds of potential energy that has been available since the Big Bang later being "released" (transformed to more active types of energy such as kinetic or radiant energy) when a triggering mechanism is available. Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. This energy is triggered and released in nuclear fission bombs or in civil nuclear power generation. Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time. Yet another example is that of a pendulum. At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum. At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy. If one (unrealistically) assumes that there is no friction or other losses, the conversion of energy between these processes would be perfect, and the pendulum would continue swinging forever." Answer:
****
[A]: energy

[Q]: Question: "Running on par with the US dollar, the Bermudian dollar takes the place of what?" Context: "In 1970 the country switched its currency from the Bermudian pound to the Bermudian dollar, which is pegged at par with the US dollar. US notes and coins are used interchangeably with Bermudian notes and coins within the islands for most practical purposes; however, banks levy an exchange rate fee for the purchase of US dollars with Bermudian dollars. Bermudian notes carry the image of Queen Elizabeth II. The Bermuda Monetary Authority is the issuing authority for all banknotes and coins, and regulates financial institutions. The Royal Naval Dockyard Museum holds a permanent exhibition of Bermuda notes and coins." Answer:
****
[A]: pound

[Q]: Question: "Why did Sony have to provide compensation?" Context: "The 'OtherOS' functionality was not present in the updated PS Slim models, and the feature was subsequently removed from previous versions of the PS3 as part of the machine's firmware update version 3.21 which was released on April 1, 2010; Sony cited security concerns as the rationale. The firmware update 3.21 was mandatory for access to the PlayStation Network. The removal caused some controversy; as the update removed officially advertised features from already sold products, and gave rise to several class action lawsuits aimed at making Sony return the feature or provide compensation." Answer:
****
[A]: the update removed officially advertised features from already sold products

[Q]: Question: "What happened in the 21st year of the 20th century?" Context: "Oklahoma City was home to several pioneers in radio and television broadcasting. Oklahoma City's WKY Radio was the first radio station transmitting west of the Mississippi River and the third radio station in the United States. WKY received its federal license in 1921 and has continually broadcast under the same call letters since 1922. In 1928, WKY was purchased by E.K. Gaylord's Oklahoma Publishing Company and affiliated with the NBC Red Network; in 1949, WKY-TV (channel 4) went on the air and later became the first independently owned television station in the U.S. to broadcast in color. In mid-2002, WKY radio was purchased outright by Citadel Broadcasting, who was bought out by Cumulus Broadcasting in 2011. The Gaylord family earlier sold WKY-TV in 1976, which has gone through a succession of owners (what is now KFOR-TV is currently owned by Tribune Broadcasting as of December 2013)." Answer:
****
[A]:
WKY received its federal license
