Question: 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.".

Answer: electrolytic capacitor


Question: Whose submarines, between the Germans and Soviets, were the Bermuda bases first used to look out for?, Context: Construction began in 1941 of two airbases consisting of 5.8 km2 (2.2 sq mi) of land, largely reclaimed from the sea. For many years, Bermuda's bases were used by US Air Force transport and refuelling aircraft and by US Navy aircraft patrolling the Atlantic for enemy submarines, first German and, later, Soviet. The principal installation, Kindley Air Force Base on the eastern coast, was transferred to the US Navy in 1970 and redesignated Naval Air Station Bermuda. As a naval air station, the base continued to host both transient and deployed USN and USAF aircraft, as well as transitioning or deployed Royal Air Force and Canadian Forces aircraft.

Answer: German


Question: What was done to secure the line of succession?, Context: In 1374 King Louis of Hungary approved the Privilege of Koszyce (Polish: "przywilej koszycki" or "ugoda koszycka") in Košice in order to guarantee the Polish throne for his daughter Jadwiga. He broadened the definition of who was a member of the nobility and exempted the entire class from all but one tax (łanowy, which was limited to 2 grosze from łan (an old measure of land size)). In addition, the King's right to raise taxes was abolished; no new taxes could be raised without the agreement of the nobility. Henceforth, also, district offices (Polish: "urzędy ziemskie") were reserved exclusively for local nobility, as the Privilege of Koszyce forbade the king to grant official posts and major Polish castles to foreign knights. Finally, this privilege obliged the King to pay indemnities to nobles injured or taken captive during a war outside Polish borders.
