There was exactly one substitution, made by one person. There was no second change that could allow different people to be responsible.
02The six statements
Each account contains two complete statements. Evaluate them separately, without hidden conditions or double meanings.
03The exercise’s distribution
Exactly one person told two truths, one told two lies, and one told one of each. The participants’ order does not matter.
04The culprit’s condition
The person who told two lies must be the one who changed the card. Telling one lie is not enough.
05The rule’s scope
Each name refers to the person bearing it. Every statement concerns the same change.
