While researching the migration of Arctic terns, a student took the following notes: - Arctic terns fly from their Arctic breeding grounds to the Antarctic and back each year. - The round-trip journey covers approximately 44,000 miles. - This is the longest known migration of any animal. - Recent tracking data shows some individuals travel up to 59,000 miles. - Scientists believe this incredible endurance is a result of evolutionary pressure to stay in 'eternal summer.' The student wants to emphasize the scale of the Arctic tern's migration. Which choice most effectively uses information from the given notes to accomplish this goal?

1. While many animals migrate, the Arctic tern is unique because it spends its entire life moving between the Earth's two poles.
2. Tracking data reveals that Arctic terns travel from the Arctic to the Antarctic to remain in summer-like conditions year-round.
3. Arctic terns complete an annual 44,000-mile round trip, the longest migration of any animal, with some traveling up to 59,000 miles.
4. The Arctic tern's endurance, which allows it to fly tens of thousands of miles, is believed to be the result of evolutionary pressure.
