For a research summary about a restored prairie plot, a student has made these notes:
- Context: The site had been seeded with native grasses two years earlier.
- Aim: evaluate whether restoration increased native plant cover.
- Method: the ecology team compared drone photographs with ground quadrat surveys from seeded plots and unseeded control plots.
- Additional information: the ecology team asked visitors to identify flowers from photographs to learn which wildflowers visitors could name.
- Result: seeded plots showed greater native grass cover than control plots.
- Comparison detail: the project kept observation conditions consistent so that results could be compared across groups.
The student wants to explain the process used to evaluate whether restoration increased native plant cover. Which choice most effectively uses relevant information from the notes to accomplish this goal?
