# B-later neutral own job

Fictional paper scene: Later stage-label scene. There are 5 columns A to E, left to right, and 4 rows 1 to 4, top to bottom. All cells have the same size. Up/down mean towards the top/bottom of this page; left/right across this page. One move reaches one neighbouring cell, never a diagonal. Start: A4. Target: D2. The name-card is at A1; the spare-card is at E4. Closed cells: B4. Do not enter or pass through them. Proposed instruction: 3 cells right, then 2 cells up. A supplied helper says: “The endpoint alone proves this proposed route avoids every closed cell.” This is a supplied scene. Read its whole legend before the questions; it is not a real place, a measured route or an observed journey.

Name or mark the supplied start and target positions.
