Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Role prompting in the system message: 'You are a professional customer support agent. Respond concisely and accurately.'
Role prompting explicitly sets the persona (e.g., 'You are an expert customer support agent') which guides tone and behavior. The system message is the ideal place for this.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Role prompting in the system message: 'You are a professional customer support agent. Respond concisely and accurately.'
Why this is correct
Role prompting in the system message establishes the persona and tone across all interactions.
- ✗
Chain-of-thought prompting to ensure reasoning before answering
Why it's wrong here
Chain-of-thought focuses on reasoning steps, not tone or persona.
- ✗
Zero-shot prompting with a direct instruction in the user message
Why it's wrong here
Zero-shot may not consistently enforce a persona without explicit role definition.
- ✗
Few-shot prompting with examples of professional responses in the user message
Why it's wrong here
Examples can help but are less efficient than a clear role prompt in the system message.
