Passage: A native of the Ukrainian port city of Odessa (a part of the Soviet Union until 1991), Izold Pustõlnik graduated cum laude from Odessa University in 1960 and received his Ph.D. from the University of Tartu in 1969 and his D.Sc. from Saint Petersburg State University in 1994. From the age of 27 in 1965 until his death forty-three years later, he was on the staff of Tartu Observatory where, as a research associate (promoted to senior research associate in 2000), he worked on the physics of close binary systems, theory of stellar atmospheres, interstellar medium, archaeoastronomy and history of astronomy. He was also a member of the International Astronomical Union, European Astronomical Society, Euroscience, Society for European Astronomy in Culture (SEAC) and served on the Board of Euro-Asian Astronomical Society and the Advisory Board of Astronomical and Astrophysical Transactions.

question:
Passage: The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames. 
 Link Information: The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain (particularly England and Scotland), Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 km long and 580 km wide, with an area of 570000 km2 Question: What is the area in meters of the sea that is adjacent to the Crag Group?
answer:
Answer: 570000


question:
Passage: In 2002, it was proposed that a for-profit prison corporation, Cornell Corrections, build a prison on the island. To connect the island with Ketchikan, it was originally planned that the federal government spend $175 million on building a bridge to the island, and another $75 million to connect it to the power grid with an electrical intertie. The Ketchikan Borough Assembly turned the proposal down when the administration of Governor Tony Knowles also expressed its disfavor to the idea. Eventually, the corporation's prison plans led to the exposure of the wide-ranging Alaska political corruption probe, which eventually ensnared U.S. Senator Ted Stevens. The bridge idea persisted. The 2005 Highway Bill provided for $223m to build the Gravina Island Bridge between Gravina Island and nearby Ketchikan, on Revillagigedo Island. The provisions and earmarks were negotiated by Alaska's Rep. Don Young, who chaired the House Transportation Committee and were supported by the Chair of the Senate Appropriations Committee, Alaska's Senator Stevens. This bridge, nicknamed "The Bridge to Nowhere" by critics, was intended to replace the auto ferry which is currently the only connection between Ketchikan and its airport. While the federal earmark was withdrawn after meeting opposition from Oklahoma Senator Tom Coburn, though the state of Alaska received $300 million in transportation funding, the state of Alaska continued to study improvements in access to the airport, which could conceivably include improvements to the ferry service. Despite the demise of the bridge proposal, Governor Sarah Palin spent $26 million in transportation funding for the planned access road on the island that ultimately went nowhere.
