What nickname was given to Canadian soldiers after they captured Vimy Ridge in 1917?

Discover Canada records this with one direct sentence. The guide writes: The Canadian Corps captured Vimy Ridge in April 1917, with 10,000 killed or wounded, securing the Canadians' reputation for valour as the "shock troops of the British Empire". The nickname the test wants is therefore the Shock Troops of the British Empire.

The phrase was earned through a single named battle. Discover Canada's figures are exact: "April 1917", "10,000 killed or wounded." One Canadian officer is quoted in the same passage: "It was Canada from the Atlantic to the Pacific on parade... In those few minutes I witnessed the birth of a nation." The guide marks April 9 as Vimy Day, and notes that "the Vimy Memorial in France honours those who served and died."

The nickname matters because of who used it. Within the British Empire, calling someone the "shock troops" meant they were the formation sent in for the hardest assaults — the soldiers expected to break a defended line others could not. Discover Canada attaches that reputation specifically to the Canadian Corps after the Vimy battle, not to any other Allied force in the same passage.

Vimy Ridge sits inside a longer pattern of Canadian achievement Discover Canada describes for the First World War. "More than 600,000 Canadians served in the war, most of them volunteers, out of a total population of eight million." By 1918, under General Sir Arthur Currie, the Canadian Corps fought through the last hundred days. The Vimy Ridge nickname is the moment in Discover Canada where that reputation was first sealed.

The question is testing whether new citizens have noticed an unusual descriptive phrase that Discover Canada chose to keep verbatim — "shock troops of the British Empire." The guide is unambiguous: this is the reputation Canadian soldiers secured at Vimy in April 1917.

The wrong answer choices each invent labels not used by Discover Canada. The guide uses none of those names in connection with Vimy or any other battle. The only nickname the guide attaches after Vimy is "shock troops of the British Empire."
