Boundary
No battery disassembly, powder handling or pencil composition claim comes from this card.

A fictional electronics exhibition uses a source-labelled text card F5. The 2017 USGS publication describes graphite properties relevant to electronics and lubricants. No mine/rank or current-market data is adopted.
Id
C10
Invitation
Give one source-described use relationship for the exhibition reader.
Next try
Ask for a more specific safely readable product-source label instead of guessing every device contains natural graphite.
Ordinary possible response
F5 links graphite properties with industrial uses; the exhibit is a text explanation, not a working device.
Title
Graphite industrial clue
