Canada is the second-largest country in the world by total area.

Discover Canada records this in one direct sentence. The guide writes: Canada is the second largest country on earth — 10 million square kilometres. Three oceans line Canada's frontiers: the Pacific Ocean in the west, the Atlantic Ocean in the east, and the Arctic Ocean to the north. The statement the test wants to check is therefore True.

The number itself matters. Discover Canada commits to 10 million square kilometres as Canada's land area. That places Canada second among all the countries of the world, after Russia. The guide describes Canada's three ocean frontiers — Pacific, Atlantic, and Arctic — as the borders of that vast territory, with the southern edge defined by "the Canada-United States boundary."

Canada's vast scale shapes its regions. Discover Canada divides the country into "five distinct regions": the Atlantic Provinces, Central Canada, the Prairie Provinces, the West Coast, and the Northern Territories. Each region has its own climate and economy. The northern territories alone — "the Northwest Territories, Nunavut and Yukon" — "contain one-third of Canada's land mass." So one-third of the country sits north of the provincial line, in territories with small populations but vast geography.

Canada's size is more than a number — it is a strategic asset. Discover Canada notes that "Canada and the U.S.A. are committed to a safe, secure and efficient frontier," and that "both Canada and the U.S.A." share "the world's longest undefended border." 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 second-largest country also contains some of the world's largest natural features. The True answer here is grounded in the guide's exact phrase: "the second largest country on earth."

The question is testing a basic geographic fact about Canada. Discover Canada commits to a categorical statement: Canada is the second largest country on earth. So the True statement is correct.

The False answer would contradict the guide's exact phrase. There is no qualification or caveat in the source — the guide states the second-largest position outright, with the figure of 10 million square kilometres.
