TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What is a part of capacitor?, Context: The maximum energy is a function of dielectric volume, permittivity, and dielectric strength. Changing the plate area and the separation between the plates while maintaining the same volume causes no change of the maximum amount of energy that the capacitor can store, so long as the distance between plates remains much smaller than both the length and width of the plates. In addition, these equations assume that the electric field is entirely concentrated in the dielectric between the plates. In reality there are fringing fields outside the dielectric, for example between the sides of the capacitor plates, which will increase the effective capacitance of the capacitor. This is sometimes called parasitic capacitance. For some simple capacitor geometries this additional capacitance term can be calculated analytically. It becomes negligibly small when the ratios of plate width to separation and length to separation are large.

SOLUTION: plates

PROBLEM: What was formed in 1850 to help with policing?, Context: In the American Old West, policing was often of very poor quality.[citation needed] The Army often provided some policing alongside poorly resourced sheriffs and temporarily organized posses.[citation needed] Public organizations were supplemented by private contractors, notably the Pinkerton National Detective Agency, which was hired by individuals, businessmen, local governments and the federal government. At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]

SOLUTION: Pinkerton National Detective Agency

PROBLEM: What is the Corporation?, Context: ITV Tyne Tees was based at City Road for over 40 years after its launch in January 1959. In 2005 it moved to a new facility on The Watermark business park next to the MetroCentre in Gateshead. The entrance to studio 5 at the City Road complex gave its name to the 1980s music television programme, The Tube. BBC North East and Cumbria is located to the north of the city on Barrack Road, Spital Tongues, in a building known, as the result of its colouring, as the Pink Palace. It is from here that the Corporation broadcasts the Look North television regional news programme and local radio station BBC Radio Newcastle.

SOLUTION:
ITV Tyne Tees
