Example Input: Question: How long did Milo's uncle serve in the U.S. Congress? Passage: November 1915, von Brincken married again to the San Francisco socialite Milo Abercrombie (1895-1977). Born in Houston, Texas, Milo was the niece of John W. Abercrombie, U.S. congressman from Alabama and acclaimed by noted portraitist Harrison Fisher as "California's greatest beauty". They had two children, Wilhelm Friedrich (1918-1980) and Maria A. (1917-2010). She divorced von Brincken in 1919 during his imprisonment and legally changed her and their two children's last name back to her maiden name, Abercrombie, so her children would not be "ashamed" of their name. Despite the divorce, von Brincken remained devoted to his former wife and she was able to remarry again, thanks to him. When the Roman Catholic Church forbade Abercrombie's intended marriage to U.S. Navy lieutenant Lyman K. Swenson, due to her divorce, von Brincken came forth and disclosed his earlier marriage to Alice Roedel. As both Roedel and von Brincken were Catholic, that marriage was sanctioned by the Church. Thus, the Church did not recognize von Brincken's later marriage to Abercrombie. Abercrombie and Swenson, who had both refused to marry unless it was sanctioned by the Catholic Church were then free to wed. Abercrombie and Swenson were married on August 11, 1920 by Father John Byrne at St Mary's Cathedral in San Francisco. At the wedding dinner that night, von Brincken's young son with Abercrombie, referred to as "John" and "Buster" in the press, was a "guest of honor" and toasted by his new stepfather and the officers of the submarine H-6 that he commanded, pledging, "the little chap's future to the uniform of blue." Swenson and Abercrombie had two children, Lyman K. Jr. ("Robert") and Cecilia. Abercrombie obtained an interlocutory decree of divorce from Swenson in May 1925, with the final decree a year later. Several months later, in October 1925, the newspapers speculated that Abercrombie would marry another naval officer, Lieutenant Commander Hugo W. Koehler, reputed to be the "wealthiest officer" in the Navy. The third generation of a wealthy St. Louis brewery family, Koehler had been a naval intelligence and U.S. State Department spy in South Russia during the Russian Revolution. Swenson had introduced Milo Abercrombie to Koehler in Honolulu. Koehler was in Panama with his ship, USS West Virginia (BB-48) when he read a newspaper account that he was engaged to marry Milo Abercrombie. Brushing it off, Koehler curtly told the press, "Some error," while Abercrombie did not take it so lightly. "I have been deeply humiliated", she told reporters, her eyes "wet with tears". "This is a most unkind blow of fate. I cannot possibly understand how this false rumor got about." Two years later, Koehler married Matilda Pell, the ex-wife of U.S. Congressman Herbert Pell (D-NY) and mother of future United States Senator Claiborne Pell (D-RI). In a bitter child visitation court battle in 1927 that went all the way to the California Court of Appeals, Abercrombie lost custody of her children with Swenson to him, after making baseless accusations that he had molested their four-year old daughter, Cecelia. The appellate court excoriated Abercrombie, "[I]in furtherance of a manifest determination to prevent him from ever seeing the children again, under any circumstances, she was instrumental in inspiring and promoting a scheme directly involving one of the children which had for its obvious purpose the ruination of respondent's character as a man, the bringing about of his complete disgrace as a naval officer, and the destruction of the love and affection which his children had theretofore manifested toward him." Swenson v. Swenson" (1929) 101 Cal.App. 440. In 1929, Lyman Swenson married Loretta B. Bruner (1897-1979). His son, Lyman K. Swenson Jr. ("Robert") (1923-2016) was also a US Naval officer.

Example Input: Question: How long had Royal Dutch Shell been a company for the year it purchased El Aguila? Passage:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.
