List frame purposes and references
Synthetic three-frame story uses F1 introduce O3, F2 explain O3 and F3 “See O4 dates”. Local storyboard brief is a complete O3 introduction ending at O3 dates. F3 artwork is legible, but its subject is wrong; the brief supplies no authorised O4 comparison.
| Frame | Purpose/offer | Decision |
|---|---|---|
| F1 | Introduce O3 | Keep |
| F2 | Explain O3 | Keep |
| F3 | Dates O4 | Revise to O3 |
Trace the subject through the sequence
- Read the O3 brief
- Follow each frame offer reference
- Change F3 action subject
- Recheck the whole story
Moving F3 earlier does not correct its wrong offer reference.

Show the worked answer
One, F3. Its revised action must refer to O3 dates; F1/F2 already belong to O3.
Fix the final-action mismatch
| Case | Decision or result | Reason |
|---|---|---|
| Review F3 legibility only | Incomplete check | Subject still O4 |
| Trace O3 across all frames | Find F3 mismatch | Final action breaks continuity |
