Two little quiz questions

1. Can the same buttons be sorted by shape instead?

  • Yes, with a new clear rule
  • No
  • Only after throwing some away
Answer and explanation

Yes, with a new clear rule. A different rule can make different groups.

2. What should stay consistent during one sort?

  • The chosen rule
  • The size of the table
  • The weather
Answer and explanation

The chosen rule. Changing the rule midway can mix the groups.
