[EX Q]: 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.

[EX Q]: Question: How long did the war featured in Border last? Passage:The film opens before the declaration of the Indo-Pakistani War of 1971. At a forward operating airbase, Indian Air Force Wing Commander Anand "Andy" Bajwa (Jackie Shroff), setting his stopwatch, waits for the air raid siren to go. As the siren goes, he sprints towards his MiG-21, armed, fuelled and ready for takeoff. Bajwa and his air force wingmen soon take off to an unknown airbase in Rajasthan. Once there, he is briefed by his superiors that he and his squadron are assigned to the Jaisalmer sector and have to fly the outdated and day fighter Hawker Hunter Ground attack planes (with no night vision capabilities) to support the Indian Army. He is soon joined by his brother-in-arms army Major Kuldip Singh Chandpuri (Sunny Deol) as they meet on a courier flight and speak about the possibility of the opening of the Western front in light of the East Pakistan conflict. Kuldip takes up command of a company of the 23rd Battalion Punjab Regiment, arguing the light defence being assigned to the military post of Longewala. He meets his second-in-command 2nd Lieutenant Dharamveer Bhan (Akshaye Khanna) (who happens to be the son of a 1965 Indo-Pakistani War veteran who was killed during that war) and the Company JCO Naib Subedar Mathura Das (Sudesh Berry). The company moves to a remote outpost in the deserts of Rajasthan and begin to expand the rudimentary Border Security Force (BSF) post and does the observation of the area up to the international border with Pakistan. They meet the post's BSF Assistant Commandant Bhairon Singh (Sunil Shetty), a deeply patriotic man who expresses his love for the desert.

[EX Q]: Question: How did the name of the bay where the 5th took over the 3rd division's headquarters come about? Passage:This plan was short-lived, and on 23 August 1943, the divisional headquarters, under Milford moved to the north coast of New Guinea, to take over the Salamaua campaign in its final stages. Landing at Nassau Bay, the headquarters took over from the 3rd Division and assumed control of its subordinate troops: the Australian 15th, 17th and 29th Brigades, and the US 162nd Infantry Regiment. The division occupied Salamaua on 11 September. After this, the division moved to Lae, which had been captured by the 7th Division, and between September 1943 and February 1944, its headquarters assumed the designation of HQ Lae Fortress, as the area was developed as a base for further operations around the Huon Peninsula and in the Ramu Valley. The division also undertook mopping up operations, securing small pockets of Japanese defenders left behind. By this time, the division reported to II Corps, and had adopted the jungle divisional establishment. After being re-designated once again as the 5th Division, the headquarters moved to Finschafen, assuming control of the 4th and 8th Brigades, and taking over the advance along the Rai coast towards Madang, which was secured in April 1944. Throughout the coming months, the 15th Brigade was reassigned to the division, as was the 7th Brigade, although both the 15th and 4th Brigades were returned to Australia in July and August 1944.
