Pick the most common/useful choices. +- For free-form inputs (addresses, names, numbers), provide sensible defaults so the user can pick or type their own. +- **Custom answer confirmation:** When the user selects "Other", confirm what you understood with a yes/no `AskUserQuestion` before moving on.
