# Why did it change?

What do these clues tell us about why the change happened?

1. Read or hear the [made-up record](../ordinary/O15.html). Keep its label with your work.
2. Pick one way below. You can speak, sign, use AAC, draw or direct someone’s hands.
3. Show a clue and an open question. Sharing is optional; pause when you need to.

## Choose a way

### 1

**Clue chain:** use three labelled paper links, with a fourth open link for a question.

### 2

**Cause courtroom:** privately accept/reject a claim using a note, with no person role-play or blame.

### 3

**Comic director:** choose three scene captions and narrate only the explicit causal link; include “the note reports”.
