Name the job and one reader clue.
My own try
Read the whole different source
In a pretend kit, a visitor wants the Pattern pencil. The kit card says Pattern pencil: look in the pocket labelled Stripes. The separate pocket labelled Dots has a plain pencil. This card helps find a specific pencil.
Adult reads the whole source neutrally when wanted; exact child-directed recording, pointing/sign/AAC/drawing/type/speech remain available. Match print separately; no voice/neatness/speed gate.
