In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: 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.
