While researching a topic, a student has taken the following notes:
- Leigh Torres is a marine ecologist.
- She conducted a study of blue whales in New Zealand’s South Taranaki Bight region.
- She wanted to know how ocean temperature affects where the whales forage for krill in that region.
- She found that during a marine heat wave, the whales foraged farther offshore than they had during cooler periods.
- The offshore waters, which were colder than areas closer to shore, had a higher relative abundance of krill.
The student wants to emphasize the aim of the research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?
