Input: Consider Input: Question: Is the fort built to protect Philadelphia on the Pennsylvania side still standing? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Input: Consider Input: Question: Was Vermont's GDP larger than Massachusetts' GDP the year Coolidge was born? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.

Input: Consider Input: Question: Is the river that George Washington crossed during his retreat longer than the river that Charles Cornwallis crossed in pursuit of Washington? 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.
