Which province is directly south of the Northwest Territories?

Discover Canada places the Northwest Territories in the North of Canada — sharing a southern boundary with the western provinces. The guide identifies the regions as: The Northwest Territories, Nunavut and Yukon contain one-third of Canada's land mass but have a population of only 100,000. The guide also lists Canada's regions: Atlantic Provinces, Central Canada, Prairie Provinces (Manitoba, Saskatchewan, Alberta), the West Coast (British Columbia), and the Northern Territories. The provinces directly south of the Northwest Territories are therefore all of British Columbia, Alberta, and Saskatchewan.

The Northwest Territories is one of three Northern Territories. Discover Canada commits the Northern Territories to THREE specific jurisdictions: Yukon, Northwest Territories, and Nunavut. Together these three contain one-third of Canada's land mass but only 100,000 people. So the Northwest Territories is in the middle of the three — to its west is Yukon, to its east is Nunavut, and to its south are the Prairie Provinces and British Columbia.

The Western provinces sit south. Discover Canada identifies "the Prairie Provinces — Manitoba, Saskatchewan and Alberta" and the "West Coast — British Columbia." The northern boundary of the four western provinces — Manitoba, Saskatchewan, Alberta, and British Columbia — corresponds to the southern boundary of the Northwest Territories (with the eastern part of NWT bordering Nunavut). So the provinces directly south of the Northwest Territories are British Columbia (in the west), Alberta (centre-west), Saskatchewan (centre-east), and Manitoba (which now borders Nunavut). The three named in the test question — British Columbia, Alberta, and Saskatchewan — are all directly south of the Northwest Territories.

The Northwest Territories has its own identity. Discover Canada writes: "The Northwest Territories (N.W.T.) were originally made up in 1870 from Rupert's Land and the North-Western Territory. The capital, Yellowknife (population 20,000), is called the 'diamond capital of North America.' More than half the population is Aboriginal (Dene, Inuit and Métis). The Mackenzie River, at 4,200 kilometres, is the second-longest river system in North America after the Mississippi and drains an area of 1.8 million square kilometres." So the territory has its own resources (diamonds), capital (Yellowknife), Aboriginal-majority population, and major river system. When the test asks which province is directly south of the Northwest Territories, the answer covers all three western provinces named in the options: British Columbia, Alberta, and Saskatchewan.

The question is testing whether new citizens know which provinces are directly south of the Northwest Territories. Discover Canada places the Western provinces south of the territory — including British Columbia, Alberta, and Saskatchewan. The right test answer matches that — all of the above.

None of the single-province options is wrong by itself — each one IS directly south of the Northwest Territories. But the source's geography places ALL three on the territory's southern boundary, so the only fully correct answer is "all of the above." The British Columbia option alone, the Alberta option alone, or the Saskatchewan option alone would each be partially correct but incomplete.
