Example Input: Question: Who preceded Henry Goulburn as Chief Secretary for Ireland? Passage:In 1808, Goulburn became Member of Parliament for Horsham. In 1810, he was appointed Under-Secretary of State for Home Affairs, and two and a half years later, he was made Under-Secretary of State for War and the Colonies. It was in this capacity that James Meehan named Goulburn, New South Wales after him, a naming that was ratified by Governor Lachlan Macquarie. Still retaining office in the Tory government, he became a Privy Counsellor in 1821, and shortly afterwards was appointed Chief Secretary for Ireland, a position which he held until April 1827. Here, although he was frequently denounced as he was considered an Orangeman, he had a successful period of office on the whole, and in 1823 he managed to pass the Composition for Tithes (Ireland) Act 1823. In January 1828, he was made Chancellor of the Exchequer under the Duke of Wellington; like his leader, he disliked Roman Catholic emancipation, which he voted against in 1828.

Example Input: Question: Where did the army that George Washington commanded that were pushed out of New York by British forces first formed? Passage:While 1776 had started well for the American cause with the evacuation of British troops from Boston in March, the defense of New York City had gone quite poorly. British general William Howe had landed troops on Long Island in August and had pushed George Washington's Continental Army completely out of New York by mid-November, when he captured the remaining troops on Manhattan. The main British troops returned to New York for the winter season. They left mainly Hessian troops in New Jersey. These troops were under the command of Colonel Rall and Colonel Von Donop. They were ordered to small outposts in and around Trenton. Howe then sent troops under the command of Charles Cornwallis across the Hudson River into New Jersey and chased Washington across New Jersey. Washington's army was shrinking, due to expiring enlistments and desertions, and suffered from poor morale, due to the defeats in the New York area. Most of Washington's army crossed the Delaware River into Pennsylvania north of Trenton, New Jersey, and destroyed or moved to the western shore all boats for miles in both directions. Cornwallis (under Howe's command), rather than attempting to immediately chase Washington further, established a chain of outposts from New Brunswick to Burlington, including one at Bordentown and one at Trenton, and ordered his troops into winter quarters. The British were happy to end the campaign season when they were ordered to winter quarters. This was a time for the generals to regroup, re-supply, and strategize for the upcoming campaign season the following spring.

Example Input: Question: How old was Jock Nelson's father when his son was born? Passage:John Norman "Jock" Nelson (28 May 1908 – 20 June 1991) was an Australian politician. Born in Bundaberg, Queensland, he was the son of politician Harold Nelson. Jock Nelson was educated at state schools in Darwin before becoming a jackeroo and goldminer, and later a bore contractor at Alice Springs. After serving in the military from 1942 to 1945, he became a pastoralist. In 1949, he was elected to the Australian House of Representatives as the Labor member for Northern Territory, defeating the sitting independent, Adair Blain. At this time, the member for Northern Territory could only vote on matters relating to the Territory itself. In 1963, he was re-elected unopposed, the last occasion when a member was returned to the House of Representatives in this fashion. He retired in 1966, an occasion used by the Country Party to take the seat. Nelson returned to pastoralism and served as the first Mayor of Alice Springs (1971 - 1973) before he stepped down to become the Administrator of the Northern Territory (1973–1975) before his death in 1991.
