input question: Extract the answer to the question from the following context. 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.".???
output answer: electrolytic capacitor

input question: Extract the answer to the question from the following context. Question: What died out? Context: The US ended World War I with two 3-inch AA guns and improvements were developed throughout the inter-war period. However, in 1924 work started on a new 105 mm static mounting AA gun, but only a few were produced by the mid-1930s because by this time work had started on the 90 mm AA gun, with mobile carriages and static mountings able to engage air, sea and ground targets. The M1 version was approved in 1940. During the 1920s there was some work on a 4.7-inch which lapsed, but revived in 1937, leading to a new gun in 1944.???
output answer: work on a 4.7-inch

input question: Extract the answer to the question from the following context. Question: In 1917, who was granted the right to immigrate to Palestine within a certain limit? Context: In 1922, Egypt, which had been declared a British protectorate at the outbreak of the First World War, was granted formal independence, though it continued to be a British client state until 1954. British troops remained stationed in Egypt until the signing of the Anglo-Egyptian Treaty in 1936, under which it was agreed that the troops would withdraw but continue to occupy and defend the Suez Canal zone. In return, Egypt was assisted to join the League of Nations. Iraq, a British mandate since 1920, also gained membership of the League in its own right after achieving independence from Britain in 1932. In Palestine, Britain was presented with the problem of mediating between the Arab and Jewish communities. The 1917 Balfour Declaration, which had been incorporated into the terms of the mandate, stated that a national home for the Jewish people would be established in Palestine, and Jewish immigration allowed up to a limit that would be determined by the mandatory power. This led to increasing conflict with the Arab population, who openly revolted in 1936. As the threat of war with Germany increased during the 1930s, Britain judged the support of the Arab population in the Middle East as more important than the establishment of a Jewish homeland, and shifted to a pro-Arab stance, limiting Jewish immigration and in turn triggering a Jewish insurgency.???
output answer:
the Jewish people
