C-later · The comparison that needs another field · educator account, criteria and next teachingYear 2 Science · T1 W7–8 · Staff · Staff / C later

Eligibility: After Days 36/39 with exposure checked. Complete source: Fictional guide has N1: named Moon marker 2 equal paper units above baseline B at model time K. N2: same named marker 4 equal paper units above B at later time L; paper unit size unchanged. N3:5 paper units from different origin C; relation of C/B and unit size unspecified. N4: at time M no result is supplied and whether action happened unknown. N5: at time N collection was planned but explicitly not yet attempted. These are schematic paper records, not actual sky distances.

Exact prompts and meaning

1. Which records support a comparable change? Tell the change in their units. Expected: N1/N2 same B/unit,2→4; can say 2 more equal units if useful, arithmetic precision supported rather than the main demand. Criterion: comparison justified by quantity/reference/unit/time. Next: two unrelated marked-ribbon lengths in a shared unit; include all fields before subtraction.
2. Can N3 simply be placed beside N1/N2 as the next comparable value? Expected: missing origin/unit relation, not established;5 is supplied but not comparable as-is. Criterion: keeps a known value while identifying unavailable comparison fields. Next: contrast a known number with an unknown unit in a pretend packing record.
3. Keep the difference between N4 and N5. Expected: N4 no result/unknown action; N5 explicitly planned/not attempted. Criterion: retains source-specific epistemic/action status. Next: a missing repair note versus a repair scheduled but unmade; don't replace either with 0.
4. Repair the guide's sentence “All five show the Moon moving farther away in the real sky.” Expected: only two comparable paper-baseline model values show their stated relation; others unmatched/unknown/unmade; no real celestial distance evidenced. Criterion: useful bounded communication plus explicit model limit. Next: highlight only the evidence-supported clauses in a new unrelated model caption and keep its real-world question open.

Capture and support

Keep the first response before help. Read neutrally or scribe exactly; note actual communication, operator, prompt and exposure. Source interpretation does not establish actual sky conduct. Record one descriptive state and reason: meaning evidenced here; meaning after named help; unclear here; unobserved on this route. No total or official grade conversion.
