Final answer:
Martin Frobisher's expedition to northern Canada ended in failure to find a direct route to Asia as he did not discover the Northwest Passage, a feat that was impossible due to geographical barriers.
Step-by-step explanation:
The result of Martin Frobisher's expedition to northern Canada was not the discovery of the Northwest Passage, successful colonization, or the extraction of valuable minerals. His expeditions are more accurately described as a failure to find a direct route to Asia.
For centuries, various European explorers like Henry Hudson and John Cabot sought this mythical Northwest Passage, a route that would allow ships to sail through North America to the Pacific and then to Asia. However, despite their efforts, no such passage existed as it is not possible to navigate a waterway all the way through North America to the Pacific due to geographical constraints.
