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: Is the CEO of Radioshack a female? Passage:Many store closings ensued at the mall in the early 1990s, including five chain clothing stores and a T.J. Cinnamons bakery all in late 1991 and early 1992. Despite these closures, the mall also gained Champs Sports and a dollar store, and its occupancy level of 92 percent was higher than the average occupancy rate of 85 percent for malls in the Midwestern United States at the time. Limited Brands (now L Brands) opened three stores then under its ownership in 1993: a combination Limited Express/Structure store (now known as Express and Express Men, respectively) and Victoria's Secret. The combined Limited Express/Structure took the place of Herman's World of Sporting Goods, which had closed earlier in the year. According to the mall's then-general manager, Limited Brands had wanted to open all three brands at the mall for several years, and that all three were highly demanded by shoppers due to their presence at Meridian Mall. Following these additions, Lansing and Meridian malls had nearly 60 stores in common with each other and nearly 40 others that were unique to each. In 1995, the mall received new planters and an enlarged customer service booth. Meanwhile, RadioShack and Regis Hairstylists moved to new storefronts, Lane Bryant expanded its existing store, and Buckle, Bombay Company, and Pacific Sunwear joined. These were followed in 1996 by Gymboree, Bath & Body Works, and the second Disney Store in the state of Michigan.

Question: The area where the Byzantine forces congregated to counter Arab invasions is located in which modern country? Passage:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.
