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: Reports from the fur trappers who first entered the mountains and those following mention the trail through the pass as being in long term us by the Shoshone, Bannack, Arapaho, Gros Ventre, Flat Head or Bitterroot Salish, Nez Perce, Crow and others. The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole. To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.
 Link Information: The lake is 7732 ft above sea level and covers 136 sqmi with 110 mi of shoreline. Question: How large is the lake that the trail passes south of?

Answer: Answer: 136 sqmi


Question: Passage: Brian David Henson was born in New York City, is the first born son of Jane Henson (née Nebel; 1934–2013) and Jim Henson (1936–1990). He has four siblings: Lisa (born 1960), Cheryl (born 1961), John (1965–2014), and Heather Henson (born 1970). As a child, he made several cameo appearances in some of the filmed segments his father produced for the PBS children's series Sesame Street, most notably in various segments of the "Number Song Series." As he got older, he built the very first Muppet penguin puppet for the opening "Lullaby of Broadway" segment of a season three episode of The Muppet Show, guest starring Gilda Radner. During his summer break from high school in 1980, he assisted in the bicycle sequence from The Great Muppet Caper (1981). He helped create and operate a special rigging device that was created to allow the Muppets to ride bicycles since he was skilled in the use of marionette puppets. A few years later, he similarly operated a marionette of Scooter riding a bicycle in The Muppets Take Manhattan (1984).
