A useful correction
Keep the feedback close to what you meant.
Practice starts from a clear prompt, shows the exact change, and gives you another attempt. It remains connected to language from your Story instead of drifting into an unrelated exercise.

- Read a brief reason for the change.
- Practise another natural way to express the idea.
