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: Which team was ranked the highest at the 2009 Pacific Nations Cup? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).
