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.

Question: Who won the AFC West in the years that the Raiders went 8-8 under Gruden? Passage:Under Gruden, the Raiders posted consecutive 8–8 seasons in 1998 and 1999, and leapt out of last place in the AFC West. After uniting with journeyman quarterback Rich Gannon, Gruden led the Raiders to the top of the AFC West and they made the playoffs in three consecutive seasons from 2000 to 2002 (the third season was under head coach Bill Callahan). Oakland finished 12–4 in the 2000 season, the team's most successful season in a decade, and its first division title since 1990, ultimately reaching the , where they lost, 16–3, to the eventual Super Bowl champions Baltimore Ravens. In 2001, the Raiders would return to the postseason with a 10–6 record, but in the AFC Divisional Round a negated fumble proved costly as they were defeated, 16–13, in overtime by the eventual Super Bowl champions New England Patriots. While Gruden was with the Raiders, Gruden acquired his nickname "Chucky" from Raiders defensive lineman Grady Jackson, who thought that the coach looked like the fictional character "Chucky" in the 1988 slasher movie Child's Play.

Question: What other planes were fitted with the MG 15? Passage:As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.
