The Arctic tern undertakes the longest migration of any known animal, flying roughly 44,000 miles each year between its breeding grounds in the Arctic and its winter range in Antarctic waters. Over a typical lifespan of 30 years, an individual tern may travel more than 1.5 million miles — a distance equivalent to three round trips to the Moon.
Based on the passage, which inference is most strongly supported?
- A
The Moon's distance from Earth is shorter than the tern's annual route
- B
Arctic terns spend most of their lives stationary at breeding grounds
- C
Arctic terns migrate only once during their lifetimes
- Dcheck_circle
Migration accounts for a substantial portion of an Arctic tern's lifetime activity
Explanation
Annual migration of 44,000 miles over 30 years yields enormous lifetime travel, supporting B. A contradicts annual migration; C contradicts "each year"; D contradicts the math given.
