[Q]: Question: How old was Thomas Kenan's father when he died? Passage:Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.

[Q]: Question: When was the food company that Lawlor's company wish to acquire in 1989 first found? Passage:At the 1981 general election he lost his Dáil seat in what was now the constituency of Dublin West, regained it in February 1982, but lost it again in the November 1982 general election. Lawlor regained his Dáil seat again at the 1987 general election, and was appointed Chairman of the Oireachtas Joint Committee on Commercial State-Sponsored Bodies. He resigned the position in 1989 due to his position as a non-executive director of Food Industries, a company that wished to acquire the Irish Sugar Company. In 1991 he lost his seat on Dublin City Council, and at the 1992 general election he nearly lost his Dáil seat to Tomás Mac Giolla of the Workers' Party. It is widely believed that Mac Giolla was cheated by Fianna Fáil in the election; the emergence of information that the since disgraced and jailed George Redmond was one of the local government officials who conducted the election count has added weight to this view.
