# C-later · The comparison that needs another field · selected source

**Eligibility:** After Days 36/39 with exposure checked. 

## Complete original fictional account

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.

## Four questions

1. Which records support a comparable change? Tell the change in their units.

2. Can N3 simply be placed beside N1/N2 as the next comparable value?

3. Keep the difference between N4 and N5.

4. Repair the guide's sentence “All five show the Moon moving farther away in the real sky.”
