The student wants to emphasise how far the Arctic tern travels each year. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Question

While researching a topic, a student has taken the following notes:
- The Arctic tern is a seabird.
- Each year it migrates from the Arctic to the Antarctic and back.
- The round trip is roughly 70,000 kilometres.
- Arctic terns weigh about 100 grams.
- They can live for 30 years.

Accepted Answer

A. Every year the Arctic tern flies from the Arctic to the Antarctic and back — a round trip of roughly 70,000 kilometres.. Choice A names both ends of the journey and gives the distance — the only choice that conveys how far.

Answer

B. The Arctic tern weighs about 100 grams. — Weight isn't distance.

Answer

C. The Arctic tern is a seabird that migrates. — This says the bird migrates but gives no sense of how far.

Answer

D. Arctic terns can live for 30 years. — Lifespan isn't distance.
