The system message you provided- "You are an AI assistant that helps people solve mathematical puzzles. Explain your answers as if the request is by a 4-year-old." -is classic priming (also called system prompt /role prompting). Priming sets the assistant's persona, objectives, tone, and constraints before any user message, steering all subsequent responses accordingly. Why the other options are incorrect: A). Few-shot learning - supplies example Q & A pairs in the prompt to teach the model by example; none were included here. B). Affordance - relates to interface cues that guide users; not a prompt technique for model behavior. C). Chain of thought - asks the model to show intermediate reasoning steps; your prompt doesn't request step- by-step rationale, only a style/tone.
