Wayne Gretzky, known as 'The Great One,' played for the Edmonton Oilers from:

Discover Canada records this in one direct sentence. The guide writes: One of the greatest hockey players of all time, Wayne Gretzky, played for the Edmonton Oilers from 1979 to 1988. The years the test wants are therefore 1979 to 1988.

Three commitments in one sentence. Discover Canada commits Wayne Gretzky to THREE specific facts: (1) one of the greatest hockey players of all time; (2) played for the Edmonton Oilers; and (3) from 1979 to 1988. So the source identifies Gretzky's career, team, and tenure with precision.

The Edmonton Oilers years were Gretzky's prime. Discover Canada commits Gretzky to nine seasons with the Edmonton Oilers — counting 1979 through 1988 inclusive. So the period covers Gretzky's youth and prime years in the National Hockey League. During this Edmonton tenure, the Oilers won multiple Stanley Cup championships — making Gretzky's name synonymous with both the team and the era.

Gretzky fits the broader Canadian hockey story. Discover Canada writes: "Hockey is Canada's most popular spectator sport and is considered to be the national winter sport. Ice hockey was developed in Canada in the 1800s. The National Hockey League plays for the championship Stanley Cup, donated by Lord Stanley, the Governor General, in 1892." So Gretzky's nine-year Edmonton career (1979–1988) is part of the Canadian hockey tradition that runs from Lord Stanley's 1892 trophy donation through to the modern era. The guide also names Donovan Bailey (1996 Olympic gold-medal sprinter) and Chantal Petitclerc (Paralympic gold medalist wheelchair racer) as other named Canadian sporting figures. Among them, Wayne Gretzky stands as "one of the greatest hockey players of all time" — a Canadian sporting hero whose Edmonton Oilers years dominated 1980s NHL hockey. So when the test asks Gretzky's Edmonton Oilers tenure, the source-precise answer is 1979 to 1988.

The question is testing whether new citizens know Wayne Gretzky's Edmonton Oilers years. Discover Canada commits to one period: 1979 to 1988. The right test answer matches that.

The wrong answer choices each pick a different decade or span. "1972–1982" is too early — Gretzky started with Edmonton in 1979. "1985–1995" starts too late and ends too late. "1990–1999" is entirely after the Edmonton years. Only 1979–1988 — the source's exact named span — matches.
