Problem: Extract the answer to the question from the following context. Question: What did American Idol produce for itself? Context: The dominance of American Idol in the ratings had made it the most profitable show in U.S. TV for many years. The show was estimated to generate $900 million for the year 2004 through sales of TV ads, albums, merchandise and concert tickets. By season seven, the show was estimated to earn around $900 million from its ad revenue alone, not including ancillary sponsorship deals and other income. One estimate puts the total TV revenue for the first eight seasons of American at $6.4 billion. Sponsors that bought fully integrated packages can expect a variety of promotions of their products on the show, such as product placement, adverts and product promotion integrated into the show, and various promotional opportunities. Other off-air promotional partners pay for the rights to feature "Idol" branding on their packaging, products and marketing programs. American Idol also partnered with Disney in its theme park attraction The American Idol Experience.

A: albums, merchandise
Problem: Given the question: Extract the answer to the question from the following context. Question: what type of energy is mentioned second? Context: Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.

Extract the answer to the question from the following context. Question: A slot in the road that did carry a power cable was a slot used by what type of tram? Context: Some street trams (streetcars) used conduit third-rail current collection. The third rail was below street level. The tram picked up the current through a plough (U.S. "plow") accessed through a narrow slot in the road. In the United States, much (though not all) of the former streetcar system in Washington, D.C. (discontinued in 1962) was operated in this manner to avoid the unsightly wires and poles associated with electric traction. The same was true with Manhattan's former streetcar system. The evidence of this mode of running can still be seen on the track down the slope on the northern access to the abandoned Kingsway Tramway Subway in central London, United Kingdom, where the slot between the running rails is clearly visible, and on P and Q Streets west of Wisconsin Avenue in the Georgetown neighborhood of Washington DC, where the abandoned tracks have not been paved over. The slot can easily be confused with the similar looking slot for cable trams/cars (in some cases, the conduit slot was originally a cable slot). The disadvantage of conduit collection included much higher initial installation costs, higher maintenance costs, and problems with leaves and snow getting in the slot. For this reason, in Washington, D.C. cars on some lines converted to overhead wire on leaving the city center, a worker in a "plough pit" disconnecting the plough while another raised the trolley pole (hitherto hooked down to the roof) to the overhead wire. In New York City for the same reasons of cost and operating efficiency outside of Manhattan overhead wire was used. A similar system of changeover from conduit to overhead wire was also used on the London tramways, notably on the southern side; a typical changeover point was at Norwood, where the conduit snaked sideways from between the running rails, to provide a park for detached shoes or ploughs.

Q: Extract the answer to the question from the following context. Question: Which is not a last name, Planck or Heisenberg? Context: Bohr also introduced the quantity , now known as the reduced Planck constant, as the quantum of angular momentum. At first, Bohr thought that this was the angular momentum of each electron in an atom: this proved incorrect and, despite developments by Sommerfeld and others, an accurate description of the electron angular momentum proved beyond the Bohr model. The correct quantization rules for electrons in which the energy reduces to the Bohr model equation in the case of the hydrogen atom were given by Heisenberg's matrix mechanics in 1925 and the Schrodinger wave equation in 1926: the reduced Planck constant remains the fundamental quantum of angular momentum. In modern terms, if J is the total angular momentum of a system with rotational invariance, and Jz the angular momentum measured along any given direction, these quantities can only take on the values
A: Planck
[Q]: Extract the answer to the question from the following context. Question: Who finally accomplished what other emperors had tried to do? Context: As the Soga clan had taken control of the throne in the sixth century, the Fujiwara by the ninth century had intermarried with the imperial family, and one of their members was the first head of the Emperor's Private Office. Another Fujiwara became regent, Sessho for his grandson, then a minor emperor, and yet another was appointed Kampaku. Toward the end of the ninth century, several emperors tried, but failed, to check the Fujiwara. For a time, however, during the reign of Emperor Daigo (897-930), the Fujiwara regency was suspended as he ruled directly.
