Task: Question Generation
Input (English): Context_1 : The Eklutna River is a 22-mile (35 km) long river located in the Southcentral region of the U.S. state of Alaska. A degraded anadromous stream of glacial origin, it originates at Eklutna Glacier and flows through Eklutna Lake and a canyon up to 350 feet (107 m) deep, emptying into the Knik Arm of Cook Inlet approximately 17 miles (27 km) northeast of Anchorage. It has one significant tributary, Thunderbird Creek, which enters the south bank about 1 km (0.6 mi) upstream from where the river exits the canyon and forms an alluvial fan. Due to water impoundments on the Eklutna River for power generation, Thunderbird Creek is currently the main source of water in the river. The river is located entirely within the limits of the Municipality of Anchorage. Context_2 : The Berg River (also called Great Berg River or in Afrikaans: Bergrivier) is a river located just north of Cape Town in the Western Cape Province of South Africa. It is approximately 294 km (183 mi) long with a catchment area of 7,715 km² (2979 mi²) and outlets into the Atlantic Ocean. About 65% of the Berg River area is under agriculture. The major towns in the Berg River area are Velddrif and Laaiplek near the coast, Piketberg, Hopefield, Moorreesburg and Darling further inland, and Wellington and Paarl in the upper catchment. The lead source of the Berg River is south of Franschhoek in the Drakenstein Mountains. Context_3 : The Kazan River (Inuktitut "Harvaqtuuq", Inuktitut syllabics ᓴᕐᕙᖅᑑᖅ; meaning "strong rapids", "the big drift" or "place of much fast flowing water"), is a Canadian Heritage River located in Nunavut, Canada. The Dene name for the river was Kasba-tue meaning “white partridge river.” The name was apparently changed to Kazan in the late 19th century due to the influence of Order of Mary Immaculate missionaries. The river headwaters are in northern Saskatchewan at Kasba Lake, and it flows north for about 1000 km (621 mi) before emptying into Baker Lake ( ), on the opposite side of the mouth of the Thelon River. Along its course the river flows through several lakes, including Ennadai Lake and Yathkyed Lake, over the Kazan Falls (25 m ), down a red sandstone gorge and through both boreal forest and tundra. It is the last section of the river, below Ennadai Lake, that is above the timber line and is designated a Canadian Heritage River. Context_4 : The Derwent River is a river located in Tasmania, Australia. The river rises in the state's Central Highlands and descends more than 700 m over 200 km , flowing through Hobart, the state's capital city, before emptying into Storm Bay and flowing into the Tasman Sea. The banks of the Derwent were once covered by forests and occupied by Tasmanian Aborigines. European settlers farmed the area and during the 20th century many dams were built on its tributaries for the generation of hydro-electricity. The River Derwent Starts at Lake St Clair. Context_5 : The Poteau River is a 141-mile (227 km) long river located in the U.S. states of Arkansas and Oklahoma. It is the only river in Oklahoma that flows north and is the seventh largest river in the state. It is a tributary of the Arkansas River, which itself is a tributary of the Mississippi River. Context_6 : The Bald River is a river located in Monroe County, Tennessee in the Cherokee National Forest. It is a tributary of the Tellico River. Just before it empties into the Tellico, the river falls over a large waterfall, Bald River Falls, which is variously reported as being between 80 and 100 feet (25 and 30 m) high. The river then flows under a bridge on Forest Service Road 120 (the falls and the river mouth are both very readily visible from the bridge). The falls is regarded as the most impressive and scenic waterfall in East Tennessee. The river is short in length but powerful as it flows through a steep, densely wooded valley and it is constantly replenished by the area's frequent rains. It rises just north of the North Carolina state line near the crest of the Unicoi Mountains and flows northeast for a short distance before turning to the northwest. Context_7 : The Ducie River is a river located on the Cape York Peninsula in Far North Queensland, Australia. Context_8 : The Wicomico River is a 13.0 mi tributary of the lower tidal portion of the Potomac River located in the U.S. state of Maryland south of Washington, DC. The river empties into the Potomac at Cobb Island and St. Margaret's Island. Its watershed area (excluding water) is 77 sqmi , with 2% impervious surface in 1994. in Charles, St. Mary's, and southern Prince George's counties. The lower section of the river forms part of the boundary between Charles and St. Mary's counties. The Wicomico River was designated a Scenic River under the Maryland Scenic River Act in 1968, and there are Scenic River Commissions for it in both Charles and St. Mary's counties (see links below). Context_9 : Queensland (abbreviated as QLD, or less frequently Q) is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. The state is the world's sixth largest sub-national entity, with an area of 1,852,642 km. Context_10 : In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and often in excess of many km). Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) "intrusive" or "non-intrusive", depending on the needs of the survey team (and the risk of destroying archaeological evidence if intrusive methods are used) and; (b) "extensive" or "intensive", depending on the types of research questions being asked of the landscape in question. Surveys can be a practical way to decide whether or not to carry out an excavation (as a way of recording the basic details of a possible site), but may also be ends in themselves, as they produce important information about past human activities in a regional context. fact_1 : The Ducie River is a river located on the Cape York Peninsula in Far North Queensland, Australia. fact_2 : Queensland (abbreviated as QLD, or less frequently Q) is the second-largest and third-most-populous state in the Commonwealth of Australia. fact_3 :  The state is the world's sixth largest sub-national entity, with an area of 1,852,642 km. Answer: 1,852,642
Output (English): The Ducie River is a river located in a state with an area of how many km?
