## Boundary

The display does not reveal a manufacturer or demonstrate refining.

## Complete source

Fictional museum cards list bauxite ore, alumina, aluminium metal and rolled foil; order and process are supplied from F1. A fifth manufacturer-space is empty.

## Id

C03

## Invitation

Arrange the four cards and explain one name change to a visitor.

## Next try

Choose one question for the empty manufacturer-space without inventing a supplier.

## Ordinary possible response

The ore and foil have different names because the source describes processing and making stages.
