Input: Read this: The contacts gained through university and American Assembly fund-raising activities would later become important supporters in Eisenhower's bid for the Republican party nomination and the presidency. Meanwhile, Columbia University's liberal faculty members became disenchanted with the university president's ties to oilmen and businessmen, including Leonard McCollum, the president of Continental Oil; Frank Abrams, the chairman of Standard Oil of New Jersey; Bob Kleberg, the president of the King Ranch; H. J. Porter, a Texas oil executive; Bob Woodruff, the president of the Coca-Cola Corporation; and Clarence Francis, the chairman of General Foods.
Question: Aside from his university work, where did Eisenhower gain useful contacts?

Output: American Assembly

Input: Read this: The company, which benefited from the imperial patronage, soon expanded its commercial trading operations, eclipsing the Portuguese Estado da India, which had established bases in Goa, Chittagong, and Bombay, which Portugal later ceded to England as part of the dowry of Catherine de Braganza. The East India Company also launched a joint attack with the Dutch United East India Company on Portuguese and Spanish ships off the coast of China, which helped secure their ports in China. The company established trading posts in Surat (1619), Madras (1639), Bombay (1668), and Calcutta (1690). By 1647, the company had 23 factories, each under the command of a factor or master merchant and governor if so chosen, and 90 employees in India. The major factories became the walled forts of Fort William in Bengal, Fort St George in Madras, and Bombay Castle.
Question: When was the Bombay trading post destroyed?

Output: unanswerable

Input: Read this: Humbert of Romans, the master general of the order from 1254 to 1263, was a great administrator, as well as preacher and writer. It was under his tenure as master general that the sisters in the order were given official membership. Humbert was a great lover of languages, and encouraged linguistic studies among the Dominicans, primarily Arabic, because of the missionary work friars were pursuing amongst those led astray or forced to convert by Muslims in the Middle East. He also wanted his friars to reach excellence in their preaching, and this was his most lasting contribution to the order. The growth of the spirituality of young preachers was his first priority. He once cried to his students: "... consider how excellent this office [of preaching] is, because it is apostolic; how useful, because it is directly ordained for the salvation of souls; how perilous, because few have in them, or perform, what the office requires, for it is not without great danger ... , vol. xxv. (Lyon, 1677)
Question: During whose tenure was the sisters of the order not given official membership?

Output: unanswerable

Input: Read this: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.
Question: How is the brightness of a light changed?

Output:
unanswerable
