What must survive when a briefing becomes shorter?
Write your own six-line briefing. Preserve a condition under a word budget and test the resulting answer.
Keep complete lines from the beginning until the budget is exhausted. Report whether declared essential lines survived.
Cut these cards apart. Use the original example first, then let a partner supply a changed case. Keep sealed/final cards with the teacher until the learner commits a rule.
