Input: Consider Input: Question: In 1958 how many total members were there in the American Philosophical Society? Passage:He was educated in the German Gymnasium, where he learned the classical languages, and trained as an Indo-Europeanist and a historical and comparative linguist in universities in Munich, Zurich, Padua, and Florence. His refugee status compelled these moves (his grandparents were Jewish, and by 1933 Jews were forbidden to attend German universities). In 1939 he escaped to the United States, where he was at first a research assistant at Yale. He taught at the University of Pennsylvania from 1948 until his retirement in 1985. He was a member of the Linguistic Society of America, of which he was elected President in 1958, and a member of the American Philosophical Society for more than 30 years. He was elected to the National Academy of Sciences. He spent a year at Oxford in 1976 and was elected a Corresponding Fellow of the British Academy in 1986.

Input: Consider Input: Question: How long before "Promise This" was released was the city it was recorded in established? Passage:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson. It is written in the music key of C minor with a time signature in common time and a tempo of 151 beats per minute. Cole's vocal range spans from G to E♭. The basic chord progression of the song is Cm, Cm, Cm, Cm, E♭, B♭, F, Cm, E♭, B♭ and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".

Input: Consider Input: Question: How old was Frobisher when he retired? Passage:McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.
