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.
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.
