The following notes are from a student's research on nursery-grown coral restoration: - Marine biologists raised young corals in an underwater nursery. - They attached some nursery-grown corals to sheltered reef sites. - They attached others to sites exposed to strong wave action. - After one year, survival was higher at sheltered sites than at wave-exposed sites. The student wants to finish the paragraph with a supported concluding statement about placement in coral restoration projects. Which choice most effectively uses relevant information from the notes to accomplish this goal?
