Complete held source: Original fiction. The wanted paper game job is to rest wholly inside a broad drawn harbour. One helper uses the same broad paper boat picture, flat mat, start and harbour direction for four resets. Equal drawn spaces mark resting distance from the start. Two pushes labelled gentler rest one then two spaces away. Two pushes labelled firmer but still gentle rest two then three spaces away. Actual force, full path and a next attempt were not measured or supplied. The harbour boundary is not marked in these distance records.

Exact own prompt: Can these records prove every firmer push travels farther or tell which trial fits the harbour? Explain a limit.

Descriptive criterion: Rejects universal ranking with overlap/limited resets/unmeasured force and preserves absent harbour boundary; a genuine relevant limit suffices, no fabricated fit.

Worked possibility, after own evidence: Two-space rest occurs under both labels. Four resting records with unmeasured force do not settle every next result; without the boundary they cannot show wholly inside.

Full source: Original unrelated fiction. A same-start paper cue rests one then two equal spaces under gentler labels and two then three under firmer labels. Force is unmeasured. The wanted stop-place boundary is absent.

Own invitation: What cannot be settled from these records?

Teach: Read the four distances without drawing a goal boundary. Invite a useful unknown about fit or every next push. If the learner asks for the boundary, acknowledge that the source does not contain it rather than adding it.

Observe: Missing boundary and/or overlap/limited force labels prevents a fabricated fit or universal farther rule.

Record the first exact evidence before help. A later source requires an actually recorded separate teaching opportunity. Source reasoning does not award an unperformed procedure or observation. Declined/not offered/not elicited/selected relation not shown remain distinct. This is not an official band or an annual grade.
