Seats across the aisle
Medium · ALDER SCREENING ROOM
An unsigned note describes a seat rather than naming its occupant. Four audience members volunteered their names. Also reconstruct the review register: it records who examined which source, independently of whether their later proposed answer is correct. Review slots describe order, not travel or clock times.
Read the case file below, or open the interactive desk to examine records, keep notes and submit your reasoning. These are the case materials, without the solution.
Your assignment
Who occupied the seat described by the note?
- The analytical records answer the analytical question; worksheet records establish the review reconstruction. Candidate proposals and supplementary recollections are claims to test.
- There are 2 ordered events. Use each listed person and item once in its column. “A immediately before B” means A is in the row directly above B, with no row between them.
- 4 verified records support the complete submission. Keep the separate context note out of the proof.
- No outside facts or unstated exceptions are required. The complete board and report are assessed together.

Case records
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
CONTEXT NOTE
Film programme
The screening began with a silent short film.
The programme does not identify a seat occupant.
PRIMARY RECORD
Front-row seating
Looking from the stage, the four occupied seats run left to right: Willa, Xeno, Yuna, Zed. Each person occupied exactly one seat.
This establishes the fixed left-to-right order.
LINKED RECORD
The unsigned note
The relevant person sat immediately to the right of Xeno, but was not at either end of the row. Use the stage view stated in the seating record.
This identifies the required relation and excludes end seats.
RECONSTRUCTION RECORD
Review register
This is the same investigation’s document review record. There are 2 ordered events, labelled Review 1, Review 2. Each listed person and item occurs exactly once. These slots describe record order, not times from the analytical problem.
- The event reviewed by Xeno Ford occupies slot 2 (Review 2).
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
RECONSTRUCTION RECORD
Review cross-check
The relationships below were verified independently. “A immediately before B” means A is in the row directly above B, with no row between them. Keep relationships from all worksheet sources together.
- The event involving “Front-row seating” occupies slot 1 (Review 1).
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.

Build your finding
Compare the records with each account. Work out what the evidence establishes, then separate that finding from anything it does not prove.
