The three techniques a writer can use to engage readers at the beginning of a narrative are:
1. **Introducing a situation** - This helps to set the stage for the story and pulls readers into the immediate context.
2. **Setting out a problem** - Presenting a conflict or challenge early on can create curiosity and investment in how the problem will be resolved.
3. **Making an interesting observation** - Engaging readers with thought-provoking or compelling observations can pique their interest and encourage them to read further.
These techniques can effectively capture attention and draw readers into the narrative.
