Input: Consider Input: Question: How long before Fort Mercer built was the city it was built to protect established? 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.


Output: 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


Input: Consider Input: Question: When was the chronicle Liber fundationis completed? Passage:The first recorded sentence in the Polish language reads: "Day ut ia pobrusa, a ti poziwai" ("Let me grind, and you take a rest") — a paraphrase of the Latin "Sine, ut ego etiam molam." The work, in which this phrase appeared, reflects the culture of early Poland. The sentence was written within the Latin language chronicle Liber fundationis from between 1269 and 1273, a history of the Cistercian monastery in Henryków, Silesia. It was recorded by an abbot known simply as Piotr (Peter), referring to an event almost a hundred years earlier. The sentence was supposedly uttered by a Bohemian settler, Bogwal ("Bogwalus Boemus"), a subject of Bolesław the Tall, expressing compassion for his own wife who "very often stood grinding by the quern-stone." Most notable early medieval Polish works in Latin and the Old Polish language include the oldest extant manuscript of fine prose in the Polish language entitled the Holy Cross Sermons, as well as the earliest Polish-language Bible of Queen Zofia and the Chronicle of Janko of Czarnków from the 14th century, not to mention the Puławy Psalter.


Output: The sentence was written within the Latin language chronicle Liber fundationis from between 1269 and 1273, a history of the Cistercian monastery in Henryków, Silesia


Input: Consider Input: Question: Which river that trappers assembled pack trains at the junction of is longer? Passage:The Bad Pass Trail, also known as the Sioux Trail, was established by Native Americans on the border of present-day Montana and Wyoming as a means of access from the Bighorn Basin in Wyoming to Bison-hunting grounds in the Grapevine Creek area of Montana. Marked by stone cairns, the trail led across Bad Pass and was established in pre-Columbian times. After Europeans arrived in the area it was frequented by fur trappers and mountain men, beginning in 1824. Trappers assembled pack trains at the junction of the Shoshone River and the Bighorn River, using the Bad Pass Trail to avoid Bighorn Canyon. The trail ended at the mouth of Grapevine Creek on the Bighorn, from which the pack train could float down the Bighorn on rafts to the Yellowstone River and then to the Missouri and on to St. Louis.



Output: Trappers assembled pack trains at the junction of the Shoshone River and the Bighorn River, using the Bad Pass Trail to avoid Bighorn Canyon
