Question: How many people were employed by NASA the year Kepler was launched? Passage 1:The Kepler spacecraft is a NASA telescope equipped with photometric equipment. Launched in 2009, Kepler continuously watches 156,000 stars in a small area. A team of astronomers, hoping to learn more about hot jupiter planets and brown dwarfs, selected four F-type stars from the Kepler Input Catalog flagged as host to a Kepler Object of Interest (a transiting object that could possibly be a planet). Using three quarters of Kepler's data, the science team conducted a follow-up investigation in using the SOPHIE échelle spectrograph at the Haute-Provence Observatory in southern France, observing stars Kepler-40, Kepler-39, KOI-552 and KOI-410. Of these, conclusive evidence of a planet orbiting KOI-410 could not be found, and KOI-552 was found to be a binary star with an M-type companion. The Hot Jupiter KOI-428b was the first of these four to be confirmed.
 Passage 2:After publishing the plays Weekend (1968) and An Evening With Richard Nixon (1972) and the novel Two Sisters: A Novel in the Form of a Memoir (1970), Vidal concentrated upon the essay and developed two types of fiction. The first type is about American history, novels specifically about the nature of national politics. About those historical novels, the critic Harold Bloom said that "Vidal's imagination of American politics ... is so powerful as to compel awe". The historical novels formed the seven-book series, Narratives of Empire: (i) Burr (1973), (ii) 1876 (1976), (iii) Lincoln (1984), (iv) Empire (1987), (v) Hollywood (1990), (vi) Washington, D.C. (1967) and (vii) The Golden Age (2000). Besides U.S. history, Vidal also explored and analyzed the history of the ancient world, specifically the Axial Age (800–200 B.C.), with the novel Creation (1981). The novel was published without four chapters that were part of the manuscript he submitted to the publisher; years later, Vidal restored the chapters to the text and re-published the novel Creation in 2002.
 Passage 3:Born into the Bhatt family, she is the daughter of filmmaker Mahesh Bhatt and actress Soni Razdan. After making her acting debut as a child in the 1999 thriller Sangharsh, Bhatt played her first leading role in Karan Johar's teen drama Student of the Year (2012). She went on to establish herself with starring roles in several films produced by Johar's studio Dharma Productions, including the romances 2 States (2014), Humpty Sharma Ki Dulhania (2014), and Badrinath Ki Dulhania (2017); and the coming-of-age drama Dear Zindagi (2016). Bhatt won the Filmfare Critics Award for Best Actress for playing a kidnapping victim in the road drama Highway (2014), and two Best Actress awards at the ceremony for playing a Bihari migrant in the crime drama Udta Punjab (2016) and a spy in the thriller Raazi (2018). The latter emerged as one of Hindi cinema's biggest-earning female-led films, and her highest-grossing release came with the musical drama Gully Boy (2019).

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: Did John Abraham produce any other albums? Passage 1:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.
 Passage 2:The Akademisches Kunstmuseum (English: Academic Museum of Antiquities ) was founded in 1818 and has one of the largest collections of plaster casts of ancient Greek and Roman sculptures in the world. At this time collections of plaster casts were mainly used in the instruction of students at art academies. They were first used in the instruction of university students in 1763 by Christian Gottlob Heyne at University of Göttingen. The Akademisches Kunstmuseum in Bonn was the first of its kind, as at this time collections at other universities were scattered around universities libraries. The first director was Friedrich Gottlieb Welcker, who also held a professorship of archaeology. His tenure was from 1819 until his retirement in 1854. He was succeeded by Otto Jahn and Friedrich Wilhelm Ritschl, who shared the directorship. From 1870 to 1889 Reinhard Kekulé von Stradonitz, nephew of the famous organic chemist Friedrich August Kekulé von Stradonitz, was the director. In 1872 the museum moved to a new building that was formerly used by the department of anatomy. The building was constructed from 1823 to 1830 and designed by Karl Friedrich Schinkel and Hermann Friedrich Waesemann. Other directors of the museum were Georg Loeschcke (from 1889 to 1912), Franz Winter (from 1912 to 1929), Richard Delbrück (from 1929 to 1940), Ernst Langlotz (from 1944 to 1966), Nikolaus Himmelmann (from 1969 to 1994) and Harald Mielsch (since 1994). All directors, with the exception of Friedrich Wilhelm Ritschl held a professorship of archaeology at the university.
 Passage 3:Penzias was born in Munich, Germany, the son of Justine (née Eisenreich) and Karl Penzias, who ran a leather business. His grandparents had come to Munich from Poland and were among the leaders of the Reichenbach Strasse Shul. At age six, he and his brother Gunther were among the Jewish children evacuated to Britain as part of the Kindertransport rescue operation. Some time later, his parents also fled Nazi Germany for the U.S., and the family settled in the Garment District of New York City in 1940. In 1946, Penzias became a naturalized citizen of the United States. He graduated from Brooklyn Technical High School in 1951 and after enrolling to study chemistry at the City College of New York, he changed majors and graduated 1954 with a degree in physics, ranked near the top of his class.
