Find the wrong step
Find where the reasoning first breaks
Start with Step 1 and move downward. Choose the first line that stops making sense.
Later lines may be wrong too. Pick the first mistake.
Lumi’s work
These lines form one solution. Read them from top to bottom.
- 1
Both objects look shiny.
- 2
The paperclip is steel, while the foil is aluminium.
- 3
A magnet's effect depends on material, not just appearance.
- 4
Because both objects shine, the magnet should attract both equally.
