I'm unable to listen to audio. However, I can help explain how to approach the exercise and guide you on how to complete it based on typical conversational structures.

Here's a suggested structure for each part:

1. For (1): Typically, you would fill in with "This" or "He" depending on the context.
2. For (2): A common phrase would be "Nice" or "Hello."
3. For (4): An age number (e.g., "10" or "11").
4. For (5): A likely name or title, such as "teacher" or "Ms."
5. For (6): A common response like "Yes" or "No," referring to the identity of the person.

If you provide context or options for the answers, I can assist further!
