Question: How long after the Battle of Princeton did the war during which Fort Mercer was built end? Passage 1:The Calgary Flames selected him in the eighth round, 182nd overall at the 1981 NHL Entry Draft, and he began his professional career in 1983–84 with a 30-point season for the Colorado Flames of the Central Hockey League (CHL). He then spent the majority of three seasons in the American Hockey League (AHL) with the Moncton Golden Flames. He was named to the AHL second All-Star Team in 1984–85, and served as captain of the Golden Flames in 1985–86. DeGray appeared in one NHL game that season, making his NHL debut with Calgary on March 6, 1986, against the New York Rangers. He played a part-time role in Calgary in 1986–87; in 27 games with the Flames, DeGray scored six goals and seven assists.
 Passage 2:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
 Passage 3: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.

Question: How old was Burns when she played as Jessie Owens? Passage 1:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."
 Passage 2:From 1998 to 2001, Burns starred in Baywatch as the character Jessie Owens. In 2001, she appeared as Vicki Vale in one of several "Batman" commercials for OnStar, opposite Bruce Thomas's Batman.

Burns starred in North Shore, a prime-time soap opera that ran for 21 episodes in 2004 and 2005. In 2006, she starred in the WB series Pepper Dennis playing Kathy Dinkle. In 2009, Burns appeared in the first twelve episodes of the updated Melrose Place playing Vanessa, the most recent wife of Dr. Michael Mancini (Thomas Calabro) and mother of his older son's five-year-old son, Noah.

 Passage 3:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 2004–05 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

Question: How many children did King Casimir IV have when he purchased Malbork Castle from the Teutonic Knights? Passage 1:It was originally constructed by the Teutonic Knights, a German Catholic religious order of crusaders, in a form of an Ordensburg fortress. The Order named it Marienburg in honour of Mary, mother of Jesus. In 1457, during the Thirteen Years’ War, it was sold by the Bohemian mercenaries to King Casimir IV of Poland in lieu of indemnities and it since served as one of the several Polish royal residences and the seat of Polish offices and institutions, interrupted by several years of Swedish occupation, and fulfilling this function until the First Partition of Poland in 1772. From then on the castle was under German rule for over 170 years. Following Germany's defeat in World War II in 1945, the land was assigned to Poland by the Allies. Heavily damaged, the castle was renovated under the auspices of modern-day Poland in the second half of the 20th century and most recently in 2016. Nowadays, the castle hosts exhibitions and serves as a museum.
 Passage 2:The far-right tradition in France finds its origins in the Third Republic with Boulangism and the Dreyfus Affair. The modern "far right" or radical right grew out of two separate events of 1889: the splitting off in the Socialist International of those who chose the nation and the culmination of the "Boulanger Affair", which championed the demands of the former Minister of War General Georges Boulanger. The Dreyfus Affair provided one of the political division lines of France. Nationalism, which had been before the Dreyfus Affair a left-wing and Republican ideology, turned after that to be a main trait of the right-wing and, moreover, of the far right. A new right emerged, and nationalism was reappropriated by the far right who turned it into a form of ethnic nationalism, itself blended with anti-Semitism, xenophobia, anti-Protestantism and anti-Masonry. The Action française, first founded as a review, was the matrix of a new type of counter-revolutionary right-wing, and continues to exist today. During the interwar period, the Action française (AF) and its youth militia, the Camelots du Roi, were very active. Far right leagues organized riots.
 Passage 3:The co-founder and executive director is Daniel B. Fisher, now a board-certified psychiatrist. A graduate of Princeton University, he completed a PhD in biochemistry at the University of Wisconsin, medical training at George Washington University, and a psychiatric residency at Harvard Medical School. While working as a biomedical researcher at the National Institute of Mental Health before he was a psychiatrist, Fisher had a psychotic episode including hallucinations and delusions. After three months at Bethesda Naval Hospital at age 25, which included forced seclusion and antipsychotic haloperidol, he was discharged with a diagnosis of schizophrenia. He was involuntarily hospitalized three times. He reports being influenced by those who were able to show they cared about the person inside and gave him hope that he might some day recover. He went on to become a psychiatrist. He was told during psychiatric training that "You can’t talk to an illness" but believed that talking to the person inside is a key method for building trust and recovery. He has since worked as a psychiatrist in hospitals and clinics, while also being a part of the consumer movement. He said that a very significant part of the reason for becoming a psychiatrist was wanting to bring to the field what he wished had been there when he was going through psychosis He was a member of the White House Commission on Mental Health, 2002-03.
