question:
Question: Where was the Hudson's Bay Company headquartered when it controlled the Vancouver Island area? Passage:The Colony of Vancouver Island had been created in 1849 to bolster British claims to the whole island and the adjacent Gulf Islands, and to provide a North Pacific home port for the Royal Navy at Esquimalt. By the mid-1850s, the Island Colony's non-indigenous population was around 800 people; a mix of mostly British, French-Canadian, Metis, Hawaiians, but with handfuls of Iroquoians and Cree in the employ of the fur company, and a few Belgian and French Oblate priests (thousands of First Nations died due to the smallpox epidemic). Three years earlier, the Treaty of Washington had established the boundary between British North America and the United States of America west of the Rocky Mountains along the 49th parallel. The mainland area of present-day British Columbia, Canada was an unorganised territory under British sovereignty until 1858. The region was under the de facto administration of the Hudson's Bay Company, and its regional chief executive, James Douglas, who also happened to be Governor of Vancouver Island. The region was informally given the name New Caledonia, after the fur-trading district which covered the central and northern interior of the mainland west of the Rockies.

question:
Question: Is Prague the capital of a country? Passage:In the months following up to the September 11 attacks, officials at the Czech Interior Ministry asserted that Atta made a trip to Prague on April 8, 2001, to meet with an Iraqi intelligence agent named Ahmed Khalil Ibrahim Samir al-Ani. This piece of information was passed on to the FBI as "unevaluated raw intelligence". Intelligence officials have concluded that such a meeting did not occur. A Pakistani businessman named Mohammed Atta had come to Prague from Saudi Arabia on May 31, 2000, with this second Atta possibly contributing to confusion. The Egyptian Mohamed Atta arrived at the Florenc bus terminal in Prague, from Germany, on June 2, 2000. He left Prague the next day, flying on Czech Airlines to Newark, New Jersey, U.S. In the Czech Republic, some intelligence officials say the source of the purported meeting was an Arab informant who approached the Czech intelligence service with his sighting of Atta only after Atta's photograph had appeared in newspapers all over the world. United States and Czech intelligence officials have since concluded that the person seen with Ani was mistakenly identified as Atta, and the consensus of investigators has concluded that Atta never attended a meeting in Prague.

question:
Question: Was the group that built the improved Devils Canyon Road formed before or after the Washington State Department of Transportation? Passage:Devils Canyon was originally home to the Portland–Spokane line of the Spokane, Portland and Seattle Railway, completed in 1908 with a small tunnel near the north bank of the Snake River. The United States Army Corps of Engineers built an improved Devils Canyon Road to connect Kahlotus to a grain facility owned by the newly established Port of Kahlotus in 1961. The Lower Monumental Dam on the Snake River was completed in February 1969 and opened in May of the same year at the south end of Devils Canyon. The rail line fell into disuse by 1987 and the right-of-way was acquired by the Washington State Park System in 1991 to become the Columbia Plateau Trail. The road was designated as State Route 263 (SR 263) in 1991 and signed into law on April 1, 1992 to serve the Port of Kahlotus, now the Port of Windust, and connect to the existing SR 260 in Kahlotus. No major revisions have occurred since the signing of the highway in 1961, however a landslide in July 2012 closed the highway for two days as Washington State Department of Transportation crews cleared up to of debris and later repairing damaged asphalt.
