The South African War (1899-1902) in which over 7,000 Canadians volunteered is also known as:

Discover Canada records this in one direct sentence about Canadian military service. The guide writes: Most Canadians were proud to be part of the British Empire. Over 7,000 volunteered to fight in the South African War (1899–1902), popularly known as the Boer War, and over 260 died. The popular name the test wants is therefore the Boer War.

Five precise commitments. Discover Canada commits the South African War to FIVE specific facts: (1) most Canadians were proud to be part of the British Empire; (2) over 7,000 Canadians volunteered; (3) the war ran from 1899 to 1902; (4) the popular name was the Boer War; (5) over 260 Canadians died. So the source is unambiguous on the named popular title, the dates, the number of volunteers, and the casualty count.

Two named Canadian battles in 1900. Discover Canada commits Canada's Boer War service to two named battle achievements: "In 1900, Canadians took part in the battles of Paardeberg ('Horse Mountain') and Lillefontein, victories that strengthened national pride in Canada." So Canadian troops fought in two named battles in 1900 — Paardeberg (described in the source as "Horse Mountain") and Lillefontein. The source describes both as "victories" that "strengthened national pride in Canada."

The Boer War sits within Canada's wider service tradition. Discover Canada commits Canada's wartime service to a longer chain of named conflicts: the Crimean War (1854 — Lieutenant Alexander Roberts Dunn earned the first Canadian V.C.); the Indian Rebellion of 1857 (Able Seaman William Hall — first black V.C. recipient); the Boer War (1899–1902 — over 7,000 Canadian volunteers); the First World War (1914–1918 — more than 600,000 Canadians served); the Second World War (1939–1945 — Hong Kong, Dieppe, Italy, Juno Beach, Netherlands); the Korean War (1950–53 — 500 dead, 1,000 wounded). So the Boer War was an early step in a long named tradition of Canadians fighting alongside Britain and other allies in international conflicts. The wider context: "Like Australia, New Zealand and other countries, Canada developed its autonomy gradually with a capacity to make significant contributions internationally." So when the test asks the popular name of the South African War in which over 7,000 Canadians volunteered, the source-precise answer is the Boer War.

The question is testing whether new citizens know the popular name of the South African War. Discover Canada commits to one popular name: the Boer War. The right test answer matches that.

The wrong answer choices each substitute a different name. The first choice's name is not in the source. The third choice's name is also not in the source. The fourth choice's name is not in the source either. Only the Boer War — the source's exact named popular title — matches.
