Problem: Given the question: Extract the answer to the question from the following context. Question: The inventor of the low voltage electrolytic capacitator with porous carbon electrodes did not know? 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.".
++++++++++++++++++++++++++++++++
The answer is:
the double layer mechanism


Problem: Given the question: Extract the answer to the question from the following context. Question: How are the farmes able to grow crops in such an unforgiving climate? Context: Despite its tropical wet and dry climate, extensive irrigation makes it a rich agricultural region. Its canal-irrigation system established by the British is the largest in the world. Wheat and cotton are the largest crops. Other crops include rice, sugarcane, millet, corn, oilseeds, pulses, vegetables, and fruits such as kinoo. Livestock and poultry production are also important. Despite past animosities, the rural masses in Punjab's farms continue to use the Hindu calendar for planting and harvesting.

Problem: Given the question: Extract the answer to the question from the following context. Question: what design did George IV prefer? Context: Remodelling of the structure began in 1762. After his accession to the throne in 1820, King George IV continued the renovation with the idea in mind of a small, comfortable home. While the work was in progress, in 1826, the King decided to modify the house into a palace with the help of his architect John Nash. Some furnishings were transferred from Carlton House, and others had been bought in France after the French Revolution. The external façade was designed keeping in mind the French neo-classical influence preferred by George IV. The cost of the renovations grew dramatically, and by 1829 the extravagance of Nash's designs resulted in his removal as architect. On the death of George IV in 1830, his younger brother King William IV hired Edward Blore to finish the work. At one stage, William considered converting the palace into the new Houses of Parliament, after the destruction of the Palace of Westminster by fire in 1834.

The answer is:
French neo-classical
