Task: Question Generation
Input (English): Context_1 : Phase 1, also known as The Phase, was a lesbian bar and nightclub at 525 8th Street, Southeast in Washington, D.C. Located one block south of Pennsylvania Avenue, SE near Eastern Market in the Capitol Hill neighborhood, Phase 1 was the oldest continually operating lesbian bar in the United States and the oldest operating LGBT bar in Washington, D.C. until its closure in February, 2016. Context_2 : The Great Dismal Swamp National Wildlife Refuge was created in 1974 to help protect and preserve a portion of the Great Dismal Swamp, a marshy region on the Coastal Plain of southeastern Virginia and northeastern North Carolina between Norfolk, Virginia, and Elizabeth City, North Carolina in the United States. It is located in parts of the independent cities of Chesapeake and Suffolk in Virginia, and the counties of Camden, Gates, and Pasquotank in North Carolina. Context_3 : Wallaceton is a historic home located at Chesapeake, Virginia. The original section was built between 1853 and 1863, as a company store. It was expanded after the American Civil War. It is a 1 1/2-story, rectangular, Greek Revival style frame dwelling. It has flat corner pilasters, a heavy box cornice under the eaves, and a full width front porch. Also on the property are a contributing two-room kitchen building and a dairy. About 1910, it was relocated approximately 100 feet to the east of the Dismal Swamp Canal to remove it from canal property. It was named for John Gallaudet Wallace (1840-1910) a farmer and businessman who fought in the Civil War for the Confederacy, as a Captain of Company C, 61st Virginia Volunteer Infantry Regiment. Context_4 : Bridgeton Township is a township in Bucks County, Pennsylvania, United States. The population was 1,277 at the 2010 census. The township was originally a part of adjacent Nockamixon Township, but a division was arranged and signed on 1890. This accord split an area of Nockamixon which ran west from the banks of the Delaware River to about one third the breadth of the original township. This smaller area was unsurprisingly named "Bridgeton", as it was the site of wooden truss bridge which connected the towns of Upper Black Eddy and Milford, New Jersey. The township originally contained several tiny hamlets, such as the aforementioned Upper Black Eddy, Narrowsville, and Ruppsville. Upper Black's Eddy, as it was originally called, and Raubsville were named for notable landholders, while Narrowsville was named for a particularly thin portion of the Delaware River. With the construction of a centralized post office in Upper Black Eddy, the usage of separate names for the smaller towns ceased in an official capacity, and the everyday errands of residents became centered on the largest of the towns. What little commercial trade exists in the township is now centered solely in Upper Black Eddy, with any evidence of there being any distinctive, smaller villages existing only on outdated road-signs and maps. Ringing Rocks Park is located within the township, as well as state game hunting lands. Bridgeton Township is also home to the Homestead General Store, the oldest continually operating general store on the Delaware Canal. Context_5 : Chain of Rocks Lock, also known as Locks No. 27, is a lock situated at the southern end of Chouteau Island near St. Louis, Missouri on the Upper Mississippi River. Its associated dam is just downstream of the Chain of Rocks Bridge, and the lock is located over 3 mi southeast on the Chain of Rocks canal. The canal and locks allow river traffic to bypass a portion of the river that is unnavigable in low water due to an anticlinal exposure of bedrock in the river—a "chain of rocks". Context_6 : Indian Creek is a partly natural and partly man-made waterway in the city of Miami Beach, Florida, United States. It starts as a man-made canal where Biscayne Bay meets Lincoln Road, and runs along Dade Boulevard, forming the boundary between South Beach and the rest of the city. At 24th street the canal opens into the natural waterway and continues north through the city past Allison Island where it opens into Biscayne Bay, till 71st Street where it merges with Normandy and Tatum Waterways and is no longer called Indian Creek. Context_7 : The Dismal Swamp Canal is located along the eastern edge of the Great Dismal Swamp in Virginia and North Carolina in the United States. It is the oldest continually operating man-made canal in the United States, opened in 1805, and closed in October 2016. It is part of the Intracoastal Waterway, an inland route, which parallels the east coast and offers boaters shelter from the Atlantic Ocean from Manasquan Inlet, New Jersey, to Brownsville, Texas. The route runs through bays, lakes, rivers, streams, and canals, and includes the Intracoastal Waterway running from Norfolk, Virginia, to the Florida Keys. Context_8 : The Clinton Street Theater is a theater located in southeast Portland, Oregon. It is believed to be the second oldest operating movie house in the city and one of the oldest continually operating cinemas in the United States. The theater was designed by Charles A. Duke in 1913, built in 1914, and opened as The Clinton in 1915. It became known as the 26th Avenue Theatre in 1945 and the Encore in 1969, before reverting to a resemblance of its original name in 1976. The Clinton often screens grindhouse, cult and experimental films, and has become known for hosting regular screenings of "The Rocky Horror Picture Show" (since 1978, marking one of the film's longest-running showings) and "Repo! The Genetic Opera". The venue also hosts the annual Filmed by Bike festival, the Faux Film Festival and the Portland Queer Documentary Film Festival. Context_9 : Moses Grandy (  1786 - unknown), was an African-American author, abolitionist, and, for more than the first four decades of his life, an enslaved person. At eight years of age he became the property of his playmate, James Grandy and two years later he was hired out for work. The monies Moses earned were collected and held until James Grandy turned 21. Grandy helped build the Great Dismal Swamp Canal and learned how to navigate boats. It was that skill that led him to be made commander of several boats that traveled the canal and Pasquotank River, transporting merchandise from Elizabeth City, North Carolina to Norfolk, Virginia. The position allowed him to be better fed, shod and dressed. Able to keep a portion of his earnings, Grandy arranged to buy his freedom twice and twice his owners kept the money and held him in slavery. An arrangement was made for an honorable man to buy him and Grandy earned the money to buy his freedom a third time, this time successfully. Context_10 : Dismal Swamp State Park is a North Carolina state park in Camden County, North Carolina in the United States. The park was created as a state natural area in 1974 with the help of The Nature Conservancy, and on July 28, 2007 the NC General Assembly re-designated it as a state park. It opened to the public in 2008. This marked the first time that public access to Great Dismal Swamp was made possible in North Carolina. The park covers 14432 acre of protected land on the North Carolina/Virginia border. Park offices are three miles (5 km) south of the border on U.S. Route 17 near South Mills. Features of the park include the canal which is used regularly by boaters using the Intracoastal Waterway and several miles of hiking and biking trails. fact_1 : Chain of Rocks Lock, also known as Locks No. 27, is a lock situated at the southern end of Chouteau Island near St. Louis, Missouri on the Upper Mississippi River. fact_2 : The Dismal Swamp Canal is located along the eastern edge of the Great Dismal Swamp in Virginia and North Carolina in the United States. fact_3 :  It is the oldest continually operating man-made canal in the United States, opened in 1805, and closed in October 2016.
