Explanation

This represents Role or Persona-based Prompting because:

• The prompt explicitly assigns a specific role ("experienced legal advisor") to the AI model
• This technique guides the model to adopt a particular persona, tone, and perspective
• By framing the AI as a legal advisor, it encourages professional, authoritative responses appropriate for legal summaries

Comparison with other options:

• Chain-of-Thought Prompting: Involves breaking down complex problems into step-by-step reasoning
• Zero-shot Prompting: Asking the model to perform tasks without any examples or specific role assignment
• Negative Prompting: Telling the model what NOT to do, rather than assigning a positive role

Role-based prompting is particularly effective for ensuring consistent tone, domain-specific language, and appropriate response style for specialized applications like legal summaries.
