The prosperity and diversity of Canada depend on:

Discover Canada records this in one direct sentence. The guide writes: The prosperity and diversity of our country depend on all Canadians working together to face challenges of the future. The condition the test wants is therefore all Canadians working together to face challenges of the future.

Two national strengths are paired. Discover Canada commits the country's continued success to TWO specific qualities: prosperity AND diversity. So the guide names both economic well-being AND the multicultural mix as the things that depend on collective Canadian effort. The two are not separate goals but linked outcomes — both rest on the same foundation of working together.

The phrasing names a future-facing duty. Discover Canada uses the phrase "face challenges of the future" — meaning the duty looks forward, not backward. So Canadians are not just keeping past achievements but actively meeting whatever comes next. The guide treats prosperity and diversity as living conditions that need ongoing collective work to sustain.

The statement is paired with a direct invitation to new citizens. Discover Canada continues: "In seeking to become a citizen, you are joining a country that, with your active participation, will continue to grow and thrive. How will you make your contribution to Canada?" So the prosperity-and-diversity statement is not an abstract observation — it is directly tied to the role of new citizens. The guide places active participation as the mechanism by which the country continues to grow and thrive. New citizens are addressed as part of the "all Canadians" who will keep the country prosperous and diverse. So when the test asks what the prosperity and diversity of Canada depend on, the source-precise answer is: all Canadians working together to face challenges of the future. The wording is direct, collective, and forward-looking — it places the duty on every Canadian, not on government alone, not on resources alone, and not on any one group.

The question is testing whether new citizens know what Canada's prosperity and diversity rest on. Discover Canada commits to one condition: all Canadians working together to face challenges of the future. The right test answer matches that.

The wrong answer choices each substitute a different agent. "The government alone making decisions" misframes the source — the named foundation is all Canadians, not government alone. "Natural resources only" reduces the country to its physical wealth and ignores the human-cooperation foundation the source names. "Immigration from specific countries" narrows the source to a single group, but the source names "all Canadians." Only the all-Canadians-working-together answer matches.
