Example Input: Question: Did Louis XIV's cousin have any siblings? Passage:After Louis XIV's marriage to Maria Theresa of Spain on 9 June 1660, Queen Anne turned her attention to the marriage of Philippe. He had previously been encouraged to court his older cousin the Duchess of Montpensier, eldest daughter of Gaston and his first wife Marie de Bourbon. Known as Mademoiselle at this time, she had an immense private fortune and had previously rejected suitors such as Charles II of England. Born in 1627, she was the sole heiress of her mother who died in childbirth. Mademoiselle declined the union, complaining that Philippe always stayed near his mother as if he was "like a child". Mademoiselle instead remained unmarried. Philippe would marry instead another first cousin, Princess Henrietta of England, youngest child of King Charles I of England and his wife Queen Henrietta Maria, who was Philippe's aunt and had taken refuge at the court of France after the birth of Princess Henrietta in 1644. They lived at the Palais Royal and at the Palais du Louvre. In 1660, after the restoration of the House of Stuart to the throne of England under her brother Charles II, Princess Henrietta returned to England to visit her sister, the Princess of Orange, who later caught smallpox and died. The French court officially asked for Henrietta's hand on behalf of Philippe on 22 November 1660 while she was in England. The couple signed their marriage contract at the Palais Royal on 30 March 1661. The ceremony took place the next day in the same building in front of select members of the court. The dowry promised was a huge 840,000 livres. Known as Henriette d'Angleterre in France, and Minette to her intimates, she was known officially as Madame and was ever popular with the court. Court gossip later said that the king was the father of Henrietta's first child. Henrietta's very open flirting is said to have caused a jealous Philippe to retaliate by beginning to flaunt his sexuality openly in a less than accepting era.

Example Input: Question: What was the population of Rome during the last year that Lucius Sextius Lateranus served as a tribune of the plebs? Passage:The gens Sextia was a plebeian family at Rome, from the time of the early Republic and continuing into imperial times. The most famous member of the gens was Lucius Sextius Lateranus, who as tribune of the plebs from 376 to 367 BC, prevented the election of the annual magistrates, until the passage of the lex Licinia Sextia, otherwise known as the "Licinian Rogations," in the latter year. This law, brought forward by Sextius and his colleague, Gaius Licinius Calvus, opened the consulship to the plebeians, and in the following year Sextius was elected the first plebeian consul. Despite the antiquity of the family, only one other member obtained the consulship during the time of the Republic. Their name occurs more often in the consular fasti under the Empire.

Example Input: Question: Who was James Dobson married to the year Henry Dobson died? Passage:He was born at Plymouth, the eldest son of George Clarisse Dobson, a civil engineer, of French descent. When he was about eight, the family moved to Holyhead, and his first school was at Beaumaris in Anglesey. He was later educated at Coventry, and the Gymnase, Strasbourg. He returned at the age of sixteen with the intention of becoming a civil engineer. (His younger brother James would in fact become a noted engineer, helping complete the Buenos Aires harbour works in the 1880s and 1890s.) At the beginning of his career, he continued to study at the South Kensington School of Art, in his spare time, but without definite ambition. In December 1856 he entered the Board of Trade, gradually rising to the rank of principal in the harbour department, from which he retired in the autumn of 1901. In 1868, he had married Frances Mary, daughter of the distinguished civil engineer Nathaniel Beardmore (1816–1872) of Broxbourne, Hertfordshire, and settled at Ealing. Dobson died in 1921 and his funeral was held on 6 September at St Peter's Church, Ealing. He is buried in the Westminster Cemetery, Uxbridge Rd, Hanwell, Middlesex.
