Input: Consider 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.

Input: Consider Input: Question: How old was the governor when Rosas was overthrown? Passage:The central figure in the overthrow of Rosas, Entre Ríos Governor Justo José de Urquiza, was granted the power of a head of state by the Palermo Protocols of April 6, 1852. This provoked resistance in Buenos Aires, however, which then refused to ratify the San Nicolás Agreement of May 31. The prospect of having the Argentine Congress headquartered in Santa Fe proved especially objectionable, and Urquiza's June 12 appointment of former President Vicente López y Planes failed to turn public opinion in Buenos Aires. Colonel Bartolomé Mitre rallied the Assembly against the San Nicolás Accords. The most contentious issue remained the Buenos Aires Customs, which remained under the control of the city government and was the chief source of public revenue. Nations with which the Confederation maintained foreign relations, moreover, kept all embassies in Buenos Aires (rather than in the capital, Paraná).
