In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: What did the supercapacitors improve?, Context: Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".

Output: electrolytic capacitor


Input: Consider Input: Where are government offices, Context: London is the seat of the Government of the United Kingdom. Many government departments are based close to the Palace of Westminster, particularly along Whitehall, including the Prime Minister's residence at 10 Downing Street. The British Parliament is often referred to as the "Mother of Parliaments" (although this sobriquet was first applied to England itself by John Bright) because it has been the model for most other parliamentary systems. There are 73 Members of Parliament (MPs) from London, who correspond to local parliamentary constituencies in the national Parliament. As of May 2015, 45 are from the Labour Party, 27 are Conservatives, and one is a Liberal Democrat.

Output: Whitehall


Input: Consider Input: What made the first two colors?, Context: The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant. With the arrival of cochineal, they had a third, carmine, which made a very fine crimson, though it had a tendency to change color if not used carefully. It was used by almost all the great painters of the 15th and 16th centuries, including Rembrandt, Vermeer, Rubens, Anthony van Dyck, Diego Velázquez and Tintoretto. Later it was used by Thomas Gainsborough, Seurat and J.M.W. Turner.
Output: the rubia tinctorum plant
