What is inscribed on the Peace Arch at the Canada-U.S. border?

Discover Canada records this in one direct sentence. The guide writes: At Blaine in the State of Washington, the Peace Arch, inscribed with the words "children of a common mother" and "brethren dwelling together in unity," symbolizes our close ties and common interests. The two inscriptions the test wants are therefore "children of a common mother" and "brethren dwelling together in unity".

The two phrases frame Canada-U.S. relations as familial. The first — "children of a common mother" — points to the shared origin of both Canada and the United States in British colonial heritage. The second — "brethren dwelling together in unity" — frames the two countries as siblings sharing a continent. Together, the inscriptions cast Canada and the U.S. as one family living next door to each other.

The Peace Arch is on the Pacific coast border. Discover Canada places it specifically "at Blaine in the State of Washington" — the U.S. side of the border opposite British Columbia. So the Peace Arch is on the western Canada-U.S. boundary, not the central or eastern stretches.

The arch fits a broader Canada-U.S. relationship. Discover Canada writes that "Canada enjoys close relations with the United States and each is the other's largest trading partner." The two countries share "the world's longest undefended border," with millions of Canadians and Americans crossing each year. "Both Canada and the U.S.A. are committed to a safe, secure and efficient frontier," and the Peace Arch is the visible monument that captures that diplomatic and human relationship in a single physical landmark.

The question is testing whether new citizens have noticed the two phrases inscribed on the Peace Arch. Discover Canada commits to two: "children of a common mother" and "brethren dwelling together in unity." The right test answer matches both.

The wrong answer choices each substitute a different phrase. "Freedom and friendship" is not inscribed on the Peace Arch in Discover Canada. "Peace and unity" appears nowhere in connection with the arch in the guide. "United we stand" is an American patriotic motto, not a Peace Arch inscription. Only the two phrases naming a common mother and brethren in unity match the source.
