Prince Edward Island is the smallest province, known for its beaches, red soil, and agriculture, especially:

Discover Canada records this in one direct sentence. The guide writes: Prince Edward Island (P.E.I.) is the smallest province, known for its beaches, red soil and agriculture, especially potatoes. The crop the test wants is therefore potatoes.

Four characteristics define PEI. Discover Canada commits Prince Edward Island to FOUR specific characteristics: (1) smallest province; (2) beaches; (3) red soil; and (4) agriculture, especially potatoes. So PEI's identity combines its tiny size with its distinctive soil colour, sandy beaches, and potato-focused agricultural economy.

The red soil and potatoes go together. Discover Canada pairs red soil and agriculture, especially potatoes as related features — meaning the iron-rich red soil of PEI is well-suited to potato cultivation. PEI is famous nationally and internationally as a potato-growing province, supplying potatoes to the rest of Canada and to export markets.

PEI has multiple distinguishing features. Discover Canada writes that PEI "is the birthplace of Confederation, connected to mainland Canada by one of the longest continuous multispan bridges in the world, the Confederation Bridge. Anne of Green Gables, set in P.E.I. by Lucy Maud Montgomery, is a much-loved story about the adventures of a little red-headed orphan girl." So PEI combines geographic distinctiveness (smallest province, red soil, beaches), agricultural identity (potatoes), historical significance (birthplace of Confederation), modern engineering (Confederation Bridge), and literary heritage (Anne of Green Gables). The capital is Charlottetown — the named site of the 1864 Confederation conferences. So when the test asks the named PEI agricultural specialty, the source-precise answer is potatoes — the iconic crop of the smallest province. The province is part of Atlantic Canada, where "coasts and natural resources, including fishing, farming, forestry and mining, have made these provinces an important part of Canada's history and development." So PEI's potato-growing fits within the Atlantic Canada agricultural identity.

The question is testing whether new citizens know PEI's named agricultural specialty. Discover Canada commits to one crop: potatoes. The right test answer matches that.

The wrong answer choices each substitute a different crop. "Wheat" is a Prairie-province crop — not associated with PEI. "Corn" is grown in many provinces but not the named PEI specialty. "Apples" are grown in various provinces (notably Ontario, BC, Nova Scotia) but not the named PEI crop. Only potatoes — the source's exact named agricultural specialty for PEI — match.
