According to the passage, Vancouver's exploration of the northwest coast of America ---- .

George Vancouver was a British naval explorer
who served as a seaman on Captain Cook's
second voyage round the world (1772-75) and as
a midshipman on his third voyage (1776-80). He
then saw service in the West Indies. In 1791 he
was placed in charge of an expedition to the
northwest coast of North America to seek for a
passage to the interior of the continent which was
rumoured to exist in those parts. On the outward
voyage by the Cape of Good Hope, a portion of
the southwest coastline of Australia was
examined, and Tasmania, New Zealand and
Hawaii were visited. Vancouver spent three years
in carefully surveying portions of the west coast of
North America. He was the first to circumnavigate
Vancouver Island, to which his name was given
by the Spaniards to commemorate his
achievement. The standard of his survey was
exceptionally high and worthy of his old captain,
James Cook; and his voyage practically disproved
the existence of a water-passage to the interior
along these coasts.
