Explanation:

To determine if the project improved biodiversity at the specific coral reef, we need data that directly compares the state before and after the project at that exact location. Data about all coral reefs (not specific to the one in question) and other projects (which don't directly relate to the impact of this particular project on biodiversity at the site) are not useful.

Answer:

• Useful Data: Animal diversity before the project at this coral reef, Animal diversity after the project at this coral reef
• Not Useful: Information about animal diversity in all coral reefs, Other projects at this coral reef during that time period
