Quebec experienced an era of rapid change in the 1960s known as:

Discover Canada records this in one direct sentence about Quebec's 1960s history. The guide writes: Quebec experienced an era of rapid change in the 1960s known as the Quiet Revolution. Many Quebecers sought to separate from Canada. The era the test wants is therefore the Quiet Revolution.

Two precise commitments. Discover Canada commits the Quiet Revolution to TWO specific facts: (1) it was an era of rapid change; (2) it took place in Quebec in the 1960s. So the source pinpoints both the place and the decade. The Quiet Revolution name reflects that the change was sweeping yet largely peaceful — transforming Quebec society without armed conflict.

The Quiet Revolution led to political changes nationally. Discover Canada commits the era's named outcome to a specific sequence: "In 1963 Parliament established the Royal Commission on Bilingualism and Biculturalism. This led to the Official Languages Act (1969), which guarantees French and English services in the federal government across" the country. So the Quiet Revolution helped trigger major federal-level recognition of French and English as Canada's two official languages — through the 1969 Official Languages Act.

The Quiet Revolution was followed by separatist activity. Discover Canada commits the post-Quiet-Revolution path to a series of named events: "Many Quebecers sought to separate from Canada... The movement for Quebec sovereignty gained strength but was defeated in a referendum in the province in 1980. After much negotiation, in 1982 the Constitution was amended without the agreement of Quebec. Though sovereignty was again defeated in a second referendum in 1995, the autonomy of Quebec within Canada remains a lively topic—part of the dynamic that continues to shape our country." So the Quiet Revolution led to a sustained nationalist movement that culminated in two failed sovereignty referendums (1980 and 1995). French-Canadian society and culture also flourished in the post-war years and into the Quiet Revolution: "French-Canadian society and culture flourished in the postwar years." The era reshaped Quebec's institutions, its educational system, and its public administration. So when the test asks the named era of rapid change in 1960s Quebec, the source-precise answer is the Quiet Revolution.

The question is testing whether new citizens know the era of rapid change in 1960s Quebec. Discover Canada commits to one named era: the Quiet Revolution. The right test answer matches that.

The wrong answer choices each substitute a different historical event. The first choice is the named 1755–63 deportation of more than two-thirds of the Acadians from their homeland — not the 1960s. The third choice is not named in Discover Canada. The fourth choice is also not named in the source. Only the Quiet Revolution — the source's exact named era — matches.
