How do I complete the Persuader challenge?
Go to the lift and talk to the woman standing in front of it.
--
The game goes as follows. She will give you a floor number, and you need to "persuade" the person in the lift to go to that floor, without actually telling them the number. You are given a set of phrases to choose from.
--
Each phrase has connotations pointing to a specific number. For example, "like peas in a pod" strongly associates with 2.
Keep doing it until the lady is satisfied.
