Original fictional puppet mechanic notes. Job: a short cue before the toy garage opens. Trial1: helper gently taps an empty plastic box once; supplied report “short tap”. Trial2: same box, helper rubs one edge once; supplied report “longer scratchy sound”. Same helper and observer spot are stated. Force was not measured. Before trials the helper predicted the two actions would give different reports. No trial with a real garage audience is supplied.

Four exact questions

1. Name the two actions and one difference in the supplied reports.
2. Which supplied clue shows what happened rather than only what was predicted?
3. For the stated short-cue job, what might you choose and why? Say what remains untried.
4. With guidance, suggest one way to keep a new action comparison similar and ask a further question.
