Discover Canada records this in one direct sentence about Yukon. The guide writes: Thousands of miners came to the Yukon during the Gold Rush of the 1890s, as celebrated in the poetry of Robert W. Service. The decade the test wants is therefore the 1890s.

Three precise commitments. Discover Canada commits the Yukon Gold Rush to THREE specific facts: (1) thousands of miners came to the Yukon; (2) the Gold Rush was in the 1890s; (3) the era is celebrated in the poetry of Robert W. Service. So the source pinpoints the scale of the migration, the named decade, and a named cultural reference.

The Gold Rush shaped Yukon's economy. Discover Canada commits Yukon's modern economy to a continuing legacy: "Mining remains a significant part of the economy." So the named 1890s Gold Rush left a lasting mark — Yukon mining continues to play a major economic role. The Gold Rush also drove infrastructure investment: "The White Pass and Yukon Railway opened from Skagway in neighbouring Alaska to the territorial capital, Whitehorse, in 1900 and provides a spectacular tourist excursion across precipitous passes and bridges." So the 1900 railway opening was a direct consequence of the Gold Rush boom.

Yukon's territorial status came soon after. Discover Canada commits Yukon's entry to Confederation to a specific year: 1898 — Yukon Territory. So the Gold Rush in the 1890s prompted the formal organisation of Yukon as a Canadian territory in 1898. The territorial capital is Whitehorse. Yukon also holds the named record for "the coldest temperature ever recorded in Canada (-63°C)." The wider context: Yukon, Nunavut, and the Northwest Territories together "contain one-third of Canada's land mass" — meaning Yukon's vast geography hosts a small population in a huge area. The named Gold Rush turned what had been remote frontier territory into a place suddenly central to Canadian history. The poet Robert W. Service was the named cultural voice of that era. So when the test asks the decade of the Yukon Gold Rush, the source-precise answer is the 1890s.

The question is testing whether new citizens know the decade of the Yukon Gold Rush. Discover Canada commits to one decade: the 1890s. The right test answer matches that.

The wrong answer choices each substitute a different decade. The first choice — the 1850s — is too early; the source places the Gold Rush in the 1890s. The second choice — the 1870s — is also too early. The fourth choice — the 1910s — is too late. Only the 1890s — the source's exact named decade — matches.
