Problem: Given the question: Extract the answer to the question from the following context. Question: How much of a financial advantage did the world's most competitive country have over others in its group when it was most prosperous? Context: The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP per capita). In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. Switzerland also has one of the world's largest account balances as a percentage of GDP.

input question: Extract the answer to the question from the following context. Question: The inventor of the low voltage electrolytic capacitator with porous carbon electrodes had what document? 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 answer: patent

Extract the answer to the question from the following context. Question: Where can they a power boost? Context: Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is used for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this.
----
Answer: an external power supply

Q: Extract the answer to the question from the following context. Question: When was the Hogen Rebellion? Context: A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hogen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.
A: 1156

Question: Extract the answer to the question from the following context. Question: What political faction did Broz join? Context: Josip Broz was born on 7 May 1892 in Kumrovec, in the northern Croatian region of Hrvatsko Zagorje in Austria-Hungary.[nb 1] He was the seventh child of Franjo and Marija Broz. His father, Franjo Broz (26 November 1860 16 December 1936), was a Croat, while his mother Marija (25 March 1864 14 January 1918), was a Slovene. His parents were married on 21 January 1891. After spending part of his childhood years with his maternal grandfather Martin Javersek in the Slovenian village of Podsreda, he entered primary school in 1900 at Kumrovec, he failed the 2nd grade and graduated in 1905. In 1907 he moved out of the rural environment and started working as a machinist's apprentice in Sisak. There, he became aware of the labour movement and celebrated 1 May Labour Day for the first time. In 1910, he joined the union of metallurgy workers and at the same time the Social-Democratic Party of Croatia and Slavonia. Between 1911 and 1913, Broz worked for shorter periods in Kamnik (19111912, factory "Titan"), Cenkov, Munich and Mannheim, where he worked for the Benz car factory; then he went to Wiener Neustadt, Austria, and worked as a test driver for Daimler.
Answer: Social-Democratic Party of Croatia and Slavonia

Please answer this: Extract the answer to the question from the following context. Question: What size tube do Yagi-Uda arrays often use? Context: Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.

tube of a diameter perhaps 1/50 of its length
