Go over there: let two readers expose the missing instruction
Show where a command lacks enough detail for consistent execution.
Ask two people to interpret the same vague command independently. Their different choices give the group evidence about missing destination or direction information, creating a reason to rewrite rather than simply declaring an answer wrong.
'Go over there' needs a defined destination.
Make the ambiguity visible
Ask two readers to interpret the same vague command independently. Their different actions reveal the missing information more clearly than an adult correction alone.
Read the command literally. Compare interpretations. Rewrite precisely.
The model's interpreter follows stated conventions. What information was missing?
Choose between clear alternatives.
