The Battle of Vimy Ridge took place in April 1917.

Discover Canada records this in one direct sentence about Canadian wartime achievements. 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 status the test wants is therefore true — the Battle of Vimy Ridge took place in April 1917.

Three precise commitments. Discover Canada commits Vimy Ridge to THREE specific facts: (1) the named force was the Canadian Corps; (2) the named action was capturing Vimy Ridge; (3) the named time was April 1917. So the source pinpoints both the named achievement and the named date.

The exact date is named precisely. Discover Canada commits the exact date to one specific named day: "the Battle of Vimy Ridge on April 9, 1917, the first time the four divisions of the Canadian Corps fought together." So the named day is April 9, 1917 — and that day is now celebrated as Vimy Day. The Vimy Memorial in France honours those who served and died in the Battle of Vimy Ridge.

Vimy is named as the birth of the nation. Discover Canada commits Canadian witness testimony to a striking phrase: a Canadian officer said "It was Canada from the Atlantic to the Pacific on parade ... In those few minutes I witnessed the birth of a nation." So Vimy Ridge is celebrated in Discover Canada as a defining moment of Canadian national identity. The Canadian Corps suffered 10,000 killed or wounded in the named victory — securing what the source calls Canada's reputation as the "shock troops of the British Empire." The wider First World War context: by the end of the war, 60,000 Canadians had been killed and 170,000 wounded. In 1918, under General Sir Arthur Currie — Canada's greatest soldier — the Canadian Corps advanced alongside French and British Empire troops in the last hundred days. The named Vimy Day every April 9 commemorates this achievement. So when the test asks whether the Battle of Vimy Ridge took place in April 1917, the source-precise answer is true.

The question is testing whether new citizens know the date of the Battle of Vimy Ridge. Discover Canada commits to one named period: April 1917 — specifically April 9, 1917. The right test answer matches that — true.

The wrong answer ("False") reverses the source — the Battle of Vimy Ridge DID take place in April 1917. The named date is exact. Only the true answer matches the source.
