[Q]: Question: How many years was Taft president? Passage:Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his father worked with a law firm. Howard attended Ithaca Academy. An interest in insect collecting encouraged by his parents with the gift of The Butterfly Hunters by Mary Treat at the age of 10 followed by more books and at the age of 13, along with another collector friend, recorded the introduction of the European cabbage butterfly (Pieris rapae) in the Catskill region. Along with his friends, he founded the Ithaca Natural History Society to meet and discuss papers and insects. While out collecting one day, he met John Henry Comstock, who invited him to his lab at Cornell University. Howard enrolled in Cornell in September 1873, three years after the death of his father, and following the advice of his mother's friends, went to study civil engineering. Doing poorly in differential calculus made him drop engineering and he began to study other subjects including French, German, and Italian. He then joined Comstock's lab as the first research student and graduated in June 1877 with a thesis on respiration in the larva of Corydalis cornutus. He worked with Burt Green Wilder and Simon Henry Gage and received a masters at Cornell. In the 1880s, he also attended Columbian College (now George Washington University) for medicine, although he didn't complete it. He however received an honorary MD from the same university in 1911 for his contribution to medical entomology.

[Q]: Question: For how many years did the man serve as President that swept all five boroughs of NYC in 1964? Passage:Roosevelt won his home state by means of a dominance of the massively populated New York City area, performing even more strongly than he had in 1932. Roosevelt took over seventy percent of the vote in the boroughs of Manhattan, Brooklyn, and the Bronx, and took over sixty percent of the vote in Queens and Staten Island. For the era, this was an historically overwhelming victory for a Democratic presidential candidate in the five boroughs of New York City, and enough to easily secure a statewide win for Roosevelt. The emergence of the New Deal Coalition was at its peak in 1936, and made American cities with their powerful political machines core bases of support for the Democratic Party. The Great Depression had accelerated the process of urbanization of the Democratic Party which had begun with the election of 1928. Roosevelt's landslide win in New York City was a fruit born by this process, and over the whole nation he achieved majorities in the largest cities totalling twice what Harding had achieved in 1920. 1936 was the third election in a row in which Democrats had won all five boroughs of NYC, following 1928 and 1932. After 1936, New York City would remain Democratic overall in every election that has followed, although no presidential candidate would sweep all five boroughs of NYC again until Lyndon Johnson in 1964. Partly as a consequence of this, FDR's 1936 victory in New York State would also be the strongest statewide Democratic performance ever in terms of both margin and vote share until 1964.
