[Q]: 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.".
[A]: electrolytic capacitor


[Q]: What ties together spiritual leader and editor?, Context: According to the New Jersey Press Association, several media entities refrain from using the term "ultra-Orthodox", including the Religion Newswriters Association; JTA, the global Jewish news service; and the Star-Ledger, New Jersey’s largest daily newspaper. The Star-Ledger was the first mainstream newspaper to drop the term. Several local Jewish papers, including New York's Jewish Week and Philadelphia's Jewish Exponent have also dropped use of the term. According to Rabbi Shammai Engelmayer, spiritual leader of Temple Israel Community Center in Cliffside Park and former executive editor of Jewish Week, this leaves "Orthodox" as "an umbrella term that designates a very widely disparate group of people very loosely tied together by some core beliefs."
[A]: Rabbi Shammai Engelmayer


[Q]: The people in Japan have more courage than the people near which sovereign nation?, Context: Historian H. Paul Varley notes the description of Japan given by Jesuit leader St. Francis Xavier (1506–1552): "There is no nation in the world which fears death less." Xavier further describes the honour and manners of the people: "I fancy that there are no people in the world more punctilious about their honour than the Japanese, for they will not put up with a single insult or even a word spoken in anger." Xavier spent the years 1549–1551 converting Japanese to Christianity. He also observed: "The Japanese are much braver and more warlike than the people of China, Korea, Ternate and all of the other nations around the Philippines."
[A]:
Philippines
